Chapter II: Part 2

"I don't know," she answered frankly. "But don't you think that it is strange--an ancestor of mine murdered and now, hundreds of years afterward, my father, the last of his line in direct descent, murdered in the same way, by an Inca dagger that has disappeared?"

"Then you were listening while I was talking to Professor Norton?" shot out Kennedy, not unkindly, but rather as a surprise test to see what she would say.

"You cannot blame me for that," she returned simply.

"Hardly," smiled Kennedy. "And I appreciate your reticence--as well as your coming here finally to tell me. Indeed, it is strange. Surely you must have some other suspicions," he persisted, "something that you feel, even though you do not know?"

Kennedy was leaning forward, looking deeply into her eyes, as if he would read what was passing in her mind. She met his gaze for a moment, then looked away.

"You heard Mr. Lockwood say that he had become associated with a Mr. Whitney, Mr. Stuart Whitney, down in Wall Street?" she ventured.

Kennedy did not take his eyes from her face as he sought to extract the reluctant words from her.

"Mr. Whitney has been largely interested in Peru, in business and in mining," she went on slowly. "He has given large sums to scholars down there, to Professor Norton's expeditions from New York. I--I'm afraid of that Mr. Whitney!"

Her quiet tone had risen to a pitch of tremulous excitement. Her face, which had been pale from the strain of the tragedy, was now full of colour, and her breast rose and fell with suppressed emotion.

"Afraid of him--why?" asked Kennedy.

There was no more reticence. Once having said so much, she seemed to feel that she must go on and tell her fears.

"Because," she went on, "he--he knows a woman--whom my father knew." A sudden flash of fire seemed to light up her dark eyes. "A woman of Truxillo," she continued, "Senora de Moche."

"De Moche," repeated Kennedy, recalling the name and a still unexplained incident of our first interview. "Who is this Senora de Moche?" he asked, studying her as if she had been under a lens.

"A Peruvian of an old Indian family," she replied, in a low tone, as if the words were forced from her. "She has come to New York with her son, Alfonso. You remember--you met him. He is studying here at the University."

Again I noted the different manner in which she spoke the two names of mother and son. Evidently there was some feud, some barrier between her and the elder woman, which did not extend to Alfonso.

Kennedy reached for the University catalogue and found the name, "Alfonso de Moche." He was, as he had told us, a post-graduate student in the engineering school and, therefore, not in any of Kennedy's own classes.

"You say your father knew the Senora?" asked Kennedy.

"Yes," she replied, in a low voice, "he had had some dealings with her. I cannot say just what they were; I do not know. Socially, of course, it was different. They did not belong to the same circle as ours in Lima."

From her tone I gathered that there existed a race prejudice between those of old Spanish descent and the descendants of the Indians. That, however, could not account for her attitude. At least with her the prejudice did not extend to Alfonso.

"Senora de Moche is a friend of Mr. Whitney?" queried Kennedy.

"Yes, I believe she has placed some of her affairs in his hands. The de Moches live at the Prince Edward Albert Hotel, and Mr. Whitney lives there, too. I suppose they see more or less of each other."

"H-m," mused Kennedy. "You know Mr. Whitney, I suppose?"

"Not very well," she answered. "Of course, I have met him. He has been to visit my father, and my father has been down at his office, with Mr. Lockwood. But I do not know much about him, except that he is what you Americans call a promoter."

Apparently, Inez was endeavouring to be frank in telling her suspicions, much more so even than Norton had been. But I could not help feeling that she was trying to shield some one, though not to the extent of consciously putting us on a wrong scent.

"I shall try to see Mr. Whitney as soon as possible," said Kennedy, as she rose to go. "And Senora de Moche, too."

I fancied that Senorita Inez, although she had not told us much, felt relieved.

Again she murmured her thanks as she left and again Kennedy repeated his injunction to tell everything that happened that could possibly have any bearing on the case.

"That's a rather peculiar phase," he considered, when we were alone, "this de Moche affair."

"Yes," I agreed. "Do you suppose that woman could be using Whitney for some purpose?"

"Or Whitney using her," suggested Kennedy. "There's so much to be done at once that I hardly know where to begin. We must see both of them as soon as possible. Meanwhile, that message from Dr. Leslie about the poison interests me. I must at least start my tests of the blood samples that I extracted. Walter, may I ask you to leave me here in the laboratory undisturbed?"

I had some writing on my news story to do, and went into the room next to the laboratory, where I was soon busily engaged tapping my typewriter. Suddenly I became conscious of that feeling, which Kennedy had hinted at, of being watched. Perhaps I had heard a footstep outside and was not consciously aware of it. But, at any rate, I had the feeling.

I stopped tapping the keys and wheeled unexpectedly about in my chair. I am sure that I caught just a fleeting glimpse of a face dodging back from the window, which was on the first floor.

Whose face it was I am not prepared to assert exactly. But there was a face, and the fleeting glimpse of the eyes and forehead was just enough to give me the impression that they were familiar, without enabling me to identify them. At any rate, the occurrence made me feel decidedly uncomfortable, especially after the warning letters that we had all received.

I sprang to my feet and ran to the door. But it was too late. The intruder had disappeared. Still, the more I thought about it, the more determined I was to try to verify an indistinct suspicion, if possible. I put on my hat and walked hurriedly over to the office of the registrar.

Sure enough, I found that Alfonso de Moche had been at the University that day, must have attended a lecture an hour or so before. Having nothing else to do, I hunted up some of his professors and tried to quiz them about him.

As I had expected, they told me that he was an excellent student, though very quiet and reserved. His mind seemed to run along the line of engineering, and particularly mining. I could not help coming to the conclusion that undoubtedly he, too, was infected by the furore for treasure hunting, in spite of his Indian ancestry.

Yet there seemed to be surprisingly little known about him outside of the lecture room and laboratory. The professors knew that he lived with his mother at a hotel downtown. He seemed to have little or nothing to do with the other students outside of class work. Altogether he was an enigma, as far as the social life of the University went. It looked very much as though he had come to New York quietly to prepare himself for the search for the buried treasure. Had the Gold of the Gods lured him into its net, too?

Reflecting on the tangle of events, the strange actions of Lockwood and the ambitions of Whitney, I retraced my steps in the direction of the laboratory, convinced that de Moche had employed at least a part of his time lately in spying on us. Perhaps he had seen Inez going in and out. Suddenly it flashed over me that the interchange of glances between de Moche and Lockwood indicated that she was more to him than a mere acquaintance. Perhaps it had been jealousy as well as treasure hunting that had prompted his eavesdropping.

Still reflecting, I decided to turn in at the Museum and have a chat with Norton. I found him nervously pacing up and down the little office that had been accorded him in his section of the building.

"I can't rid my mind of that warning," he remarked anxiously, pausing in his measured tread. "It seems inconceivable to me that any one would take the trouble to send four such warnings unless he meant it."

"Quite so," I agreed, relating to him what had just happened.

"I thought of something like that," he acquiesced, "and I have already taken some precautions."

Norton waved his hand at the windows, which I had not noticed before. Though they were some distance above the ground, I saw now that he had closed and barred them at the expense of ventilation. The warnings seemed to have made more of an impression on him than on any of the rest of us.

"One never can tell where or when a blow will fall with these people," he explained. "You see, I've lived among them. They are a hot-blooded race. Besides, as you perhaps have read, they have some queer poisons down in South America. I mean to run no unnecessary chances."

"I suppose you suspected all along that the dagger had something to do with the Gold of the Gods, did you not?" I hinted.

Norton paused before answering, as though to weigh his words. "Suspected--yes," he replied. "But, as I told you, I have had no chance to read the inscription on it. I can't say that I took it very seriously--until now."

"It's not possible that Stuart Whitney, who, I understand, is deeply interested in South America, may have had some inkling of the value of the dagger, is it?" I asked thoughtfully.

For a full minute Norton gazed at me. "I hadn't thought of that," he admitted at length. "That's a new idea to me."

Yet somehow I knew that Norton had thought of it, though he had not yet spoken about it. Was it through loyalty to the man who had contributed to financing his expeditions to South America?

"Do you know Senora de Moche well?" I ventured, a moment later.

"Fairly well," he replied. "Why?"

"What do you think of her?"

"Rather a clever woman," he replied noncommittally.

"I suppose all the people in New York who were interested in Peru knew her," I pursued, adding, "Mr. Whitney, Mendoza, Lockwood."

Norton hesitated, as though he was afraid of saying too much. While I could not help admiring his caution, I found that it was most exasperating. Still, I was determined to get at his point of view, if possible.

"Alfonso seems to be a worthy son, then," I remarked. "I can't quite make out, though, why the Senorita should have such an obvious prejudice against her. It doesn't seem to extend to him."

"I believe," replied Norton reluctantly, "that Mendoza had been on rather intimate terms with her. At least, I think you'll find the woman very ambitious for her son. I don't think she would have stopped at much to advance his interests. You must have noticed how much Alfonso thinks of the Senorita. But I don't think there was anything that could have overcome the old Castilian's prejudice. You know they pride themselves on never intermarrying. With Lockwood it would have been different."

I thought I began to get some glimmering of how things were.

"Whitney knows her pretty well now, doesn't he?" I shot out.

Norton shrugged his shoulders. But he could not have acquiesced better than by his very manner.

"Mr. Lockwood and Mr. Whitney know best what they are doing," he remarked, at length. "Why don't you and Kennedy try to see Senora de Moche? I'm a scientist, you know. I dislike talking about speculations. I'd prefer only to express opinions about things that are certainties."

Perhaps Norton wished to convey the impression that the subjects I had broached were worth looking into. At least it was the impression I derived.

"Still," he continued slowly, "I think I am justified in saying this much: I myself have been interested in watching both Alfonso de Moche and Lockwood when it comes to the case of the Senorita. All's fair, they say, in love and war. If I am any judge, there are both in this case, somewhere. I think you had better see the Senora and judge for yourself. She's a clever woman, I know. But I'm sure that Kennedy could make her out, even if the rest of us can't."

I thanked Norton for the hint that he had given, and after chatting a few moments more left him alone in his office.

In my room again, I went back to finish my writing. Nothing further occurred, however, to excite my suspicions, and at last I managed to finish it.

I was correcting what I had written when the door opened from the laboratory and Craig entered. He had thrown off his old, acid-stained laboratory smock and was now dressed to venture forth.

"Have you found out anything about the poison?" I asked.

"Nothing definite yet," he replied. "That will take some time now. It's a strange poison--an alkaloid, I'm sure, but not one that one ordinarily encounters. Still, I've made a good beginning. It won't take long to determine it now."

Craig listened with deep interest, though without comment, when I related what had happened, both Norton's conversation and about the strange visitor whom we had had peering into our windows.

"Some one seems to be very much interested in what we are doing, Walter," he concluded simply. "I think we'd better do a little more outside work now, while we have a chance. If you are ready, so am I. I want to see what sort of treasure hunter this Stuart Whitney is. I'd like to know whether he is in on this secret of the Gold of the Gods, too."

V

THE WALL STREET PROMOTER

Lockwood, as we now knew, had become allied in some way with a group of Wall Street capitalists, headed by Stuart Whitney.

Already I had heard something of Whitney. In the Street he was well known as an intensely practical man, though far above the average exploiter both in cleverness and education.

As a matter of fact, Whitney had been far-sighted enough to see that scholarship could be capitalized, not only as an advertisement, but in more direct manners. Just at present one of his pet schemes was promoting trade through the canal between the east coast of North America and the west coast of South America. He had spent a good deal of money promoting friendship between men of affairs and wealth in both New York and Lima. It was a good chance, he figured, for his investments down in Peru were large, and anything that popularized the country in New York could not but make them more valuable.

"Norton seemed rather averse to talking about Whitney," I ventured to Craig, as we rode downtown.

"That may be part of Whitney's cleverness," he returned thoughtfully. "As a patron of art and letters, you know, a man can carry through a good many things that otherwise would be more critically examined."

Kennedy did not say it in a way that implied that he knew anything very bad about Whitney. Still, I reflected, it was astute in the man to insure the cooperation of such people as Norton. A few thousand dollars judiciously spent on archaeology might cover up a multitude of sins of high finance.

Nothing more was said by either of us, and at last we reached the financial district. We entered a tall skyscraper on Wall Street just around the corner from Broadway and shot up in the elevator to the floor where Whitney and his associates had a really palatial suite of offices.

As we opened the door we saw that Lockwood was still there. He greeted us with a rather stiff bow.

"Professor Kennedy and Mr. Jameson," he said simply, introducing us to Whitney, "friends of Professor Norton, I believe. I met them to-day up at Mendoza's."

"That is a most incomprehensible affair," returned Whitney, shaking hands with us. "What do you make out of it?"

Kennedy shrugged his shoulders and turned the remark aside without committing himself.

Stuart Whitney was a typical promoter, a large, full-blooded man, with a face red and inclined to be puffy from the congested veins. His voice alone commanded respect, whether he said anything worth while or not. In fact, he had but to say that it was a warm day and you felt that he had scored a telling point in the conversation.

"Professor Norton has asked me to look into the loss of an old Peruvian dagger which he brought back from his last expedition," explained Kennedy, endeavouring to lead the conversation in channels which might arrive somewhere.

"Yes, yes," remarked Whitney, with a nod of interest. "He has told me of it. Very strange, very strange. When he came back he told me that he had it, along with a lot of other important finds. But I had no idea he set such a value on it--or, rather, that any one else might do so. It would have been easy to have safeguarded it here, if we had known," he added, with a wave of his hand in the direction of a huge chrome steel safe of latest design in the outer office.

Lockwood, I noted, was listening intently, quite in contrast with his former cavalier manner of dismissing all consideration of ancient Inca lore as academic or unpractical. Did he know something of the dagger?

"I'm very much interested in old Peruvian antiquities myself," remarked Kennedy, a few minutes later, "though not, of course, a scholar like our friend Norton."

"Indeed?" returned Whitney; and I noticed for the first time that his eyes seemed fairly to glitter with excitement.

They were prominent eyes, a trifle staring, and I could not help studying them.

"Then," he exclaimed, rising, "you must know of the ruins of Chan-Chan, of Chima--those wonderful places?"

Kennedy nodded. "And of Truxillo and the legend of the great fish and the little fish," he put in.

Whitney seemed extraordinarily pleased that any one should be willing to discuss his hobby with him. His eyes by this time were apparently starting from their sockets, and I noticed that the pupils were dilated almost to the size of the iris.

"We must sit down and talk about Peru," he continued, reaching for a large box of cigarettes in the top drawer of his big desk.

Lockwood seemed to sense a long discussion of archaeology. He rose and mumbled an excuse about having something to do in the outer office.

"Oh, it is a wonderful country, Professor Kennedy," went on Whitney, throwing himself back in his chair. "I am deeply interested in it--its mines, its railroads, as well as its history. Let me show you a map of our interests down there."

He rose and passed into the next room to get the map. The moment his back was turned, Kennedy reached over to a typewriter desk that stood in a corner of the office, left open by the stenographer, who had gone. He took two thin second sheets of paper and a new carbon sheet. A hasty dab or two of the library paste completed his work.

Carefully Craig laid the prepared paper on the floor just a few inches from the door into the outer office and scattered a few other sheets about, as though the wind had blown them off the desk.

As Whitney returned, a big map unrolled in his hands, I saw his foot fall on the double sheet that Craig had laid by the door.

Kennedy bent down and began picking up the papers.

"Oh, that's all right," remarked Whitney brusquely. "Never mind that. Here's where some of our interests lie, in the north."

I don't think I paid much more attention to the map than did Kennedy as we three bent over it. His real attention was on the paper which he had placed on the floor, as though fixing in his mind the exact spot on which Whitney had stepped.

As Whitney talked rapidly about the country, we lighted the cigarettes. They seemed to be of a special brand. I puffed mine for a moment. There was a peculiar taste about it, however, which I did not exactly like. In fact, I think that the Latin-American cigarettes do not seem to appeal to most Americans very much, anyhow.

While we talked, I noticed that Kennedy evidently shared my own tastes, for he allowed his cigarette to go out, and, after a puff or two, I did the same. For the sake of my own comfort, I drew one of my own from my case as soon as I could do so politely, and laid the stub of the other in an ash-tray on Whitney's desk.

"Mr. Lockwood and Senor Mendoza had some joint interests in the country, too, didn't they?" queried Kennedy, his eye still on the pieces of paper near the door.

"Yes," returned Whitney. "Lockwood!"

"What is it?" came Lockwood's voice from outside.

"Show Professor Kennedy where you and Mendoza have those concessions."

The young engineer strode into the room, and I saw a smile of gratification cross Kennedy's face as his foot, also, fell on the paper by the door.

Unlike Whitney, however, Lockwood bent over to gather up the sheets. But before he could actually do so Kennedy reached down and swept them just out of his reach.

"Quite breezy," Kennedy covered up his action, turning to restore the paper to the desk.

Craig had his back to them, but not to me, and I saw him fumble for an instant with the papers. Quickly he pressed his thumb-nail on one side, as though making a rough "W," while on the other side he made what might be an "L." Then he shoved the two sheets and the carbon into his pocket.

I glanced up hastily. Fortunately, neither Whitney nor Lockwood had noted his action.

For the first time, now, I noticed as I watched him that Lockwood's eyes, too, were a trifle stary, though not so noticeable as Whitney's.

"Let me see," continued Whitney, "your concessions are all about here, in the north, aren't they?"

Lockwood drew a pencil from his pocket and made several cross-marks over the names of some towns on the large map.

"Those are the points that we had proposed to work," he said simply, "before this terrible tragedy to Mendoza."

"Mining, you understand," explained Whitney. Then, after a pause, he resumed quickly. "Of course, you know that much has been said about the chances for mining investments and about the opportunities for fortunes for persons in South America. Peru has been the Mecca for fortune hunters since the days of Pizarro. But where one person has been successful thousands have failed because they don't know the game. Why, I know of one investment of hundreds of thousands that hasn't yielded a cent of profit just because of that."

Lockwood said nothing, evidently not caring to waste time or breath on any one who was not a possible investor. But Whitney had the true promoter's instinct of booming his scheme on the chance that the interest inspired might be carried to some third party.

"American financiers, it is true," he went on excitedly, taking out a beautifully chased gold cigarette case, "have lost millions in mining in Peru. But that is not the scheme that our group, including Mr. Lockwood now, has. We are going to make more millions than they ever dreamed of--because we are simply going to mine for the products of centuries of labour already done--for the great treasure of Truxillo."

One could not help becoming infected by Whitney's enthusiasm.

Kennedy was following him closely, while a frown of disapproval spread over Lockwood's face.

"Then you know the secret of the hiding-place of the treasure?" queried Kennedy abruptly.

Whitney shook his head in the negative. "It is my idea that we don't have to know it," he answered. "With the hints that we have collected from the natives, I think we can locate it with the expenditure of comparatively little time and money. Senor Mendoza has obtained the concession from the government to hunt for it on a large scale in the big mounds about Truxillo. We know it is there. Is not that enough?"

If it had been any one less than Whitney, we should probably have said it was not. But it took more than that to deny anything he asserted. Lockwood's face was a study. I cannot say that it betrayed anything except disapproval of the mere discussion of the subject. In fact, it left me in doubt as to whether Whitney himself might not have been bluffing, in the certainty of finding the treasure--perhaps had already the secret he denied having and was preparing to cover it up by stumbling on it, apparently, in some other way. I recognized in Stuart Whitney as smooth an individual as ever we had encountered. His was all the sincerity of a crook. Yet he contrived to leave the whole matter in doubt. Perhaps in this case he actually knew what he was talking about.

The telephone rang and Lockwood answered it. Though he did not mention her name, I knew from his very tone and manner that it was Senorita de Mendoza who was calling up. Evidently his continued absence had worried her.

"There's absolutely nothing to worry about," we heard him say. "Nothing has changed. I shall be up to see you as soon as I can get away from the office."

There was an air of restraint about Lockwood's remarks, not as though he were keeping anything from the Senorita, but as though he were reluctant for us to overhear anything about his affairs.

Lockwood had been smoking, too, and he added the stubs of his cigarettes to the pile in the ash-tray on Whitney's desk. Once I saw Craig cast a quick glance at the tray, and I understood that in some way he was anxious to have a chance to investigate those cigarettes.

"You saw the dagger which Norton brought back, did you not?" asked Kennedy of Whitney.

"Only as I saw the rest of the stuff after it was unpacked," he replied easily. "He brought back a great many interesting objects on this last trip."

It was apparent that whether he actually knew anything about the secret of the Inca dagger or not, Whitney was not to be trapped into betraying it. I had an idea that Lockwood was interested in knowing that fact, too. At any rate, one could not be sure whether these two were perfectly frank with each other, or were playing a game for high stakes between themselves.

Lockwood seemed eager to get away and, with a hasty glance at his watch, rose.

"If you wish to find me, I shall be with Senorita de Mendoza," he said, taking his hat and stick, and bowing to us.

Whitney rose and accompanied him to the door in the outer office, his arm on his shoulder, conversing in a low tone that was inaudible to us.

No sooner, however, had the two passed through the door, with their backs toward us, than Kennedy reached over quickly and swept the contents of the ash-tray, cigarette stubs, ashes, and all, into an empty envelope which was lying with some papers. Then he sealed it and shoved it into his pocket, with a sidelong glance of satisfaction at me.

"Evidently Mr. Lockwood and the Senorita are on intimate terms," hazarded Kennedy, as Whitney rejoined us.

"Poor little girl," soliloquized the promoter. "Yes, indeed. And Lockwood is a lucky dog, too. Such eyes, such a figure--did you ever see a more beautiful woman?"

One could not help recognizing that whatever else Whitney might have said that did not ring true his admiration for the unfortunate girl was genuine. That was not so remarkable, however. It could hardly have been otherwise.

"You are acquainted, I suppose, with a Senora de Moche?" ventured Kennedy again, taking a chance shot.

Whitney looked at him keenly. "Yes," he agreed, "I have had some dealings with her. She was an acquaintance of old Mendoza's--a woman of the world, clever, shrewd. I think she has but one ambition--her son. You have met her?"

"Not the Senora," admitted Craig, "but her son is a student at the University."

"Oh, yes, to be sure," said Whitney. "A fine fellow--but not of the type of Lockwood."

Why he should have coupled the names was not clear for the moment. But he had risen, and was moving deliberately up and down the office, his thumbs in his waistcoat pockets, as though he were thinking of something very perplexing.

"If I were younger," he remarked finally, of a sudden, "I would give both of them a race for that girl. She is the greatest treasure that has ever come out of the country. Ah, well--as it is, I would not place my money on young de Moche!"

Kennedy had risen to go.

"I trust you will be able to unearth some clue regarding that dagger," said Whitney, as we moved toward the door. "It seems to have worried Norton considerably, especially since you told him that Mendoza was undoubtedly murdered with it."

Evidently Norton kept in close touch with his patron, but Kennedy did not appear to be surprised at it.

"I am doing my best," he returned. "I suppose I may count on your help as the case develops?"

"Absolutely," replied Whitney, accompanying us out into the hall to the elevator. "I shall back Norton in anything he wants to keep the Peruvian collection intact and protected."

Our questions were as yet unanswered. Not only had we no inkling as to the whereabouts of the dagger, but the source of the four warnings that had been sent us was still as much shrouded in mystery.

Kennedy beckoned to a passing taxicab.

"The Prince Edward Albert," he directed briefly.

VI

THE CURSE OF MANSICHE

We entered the Prince Edward Albert a few minutes later, one of the new and beautiful family hotels uptown.

Before making any inquiries, Craig gave a hasty look about the lobby. Suddenly I felt him take my arm and draw me over to a little alcove on one side. I followed the direction of his eyes. There I could see young Alfonso de Moche talking to a woman much older than himself.

"That must be his mother," whispered Craig. "You can see the resemblance. Let's sit here awhile behind these palms and watch."

They seemed to be engaged in an earnest conversation about something. Even as they talked, though we could not guess what it was about, it was evident that Alfonso was dearer than life to the woman and that the young man was a model son. Though I felt that I must admire them each for it, still, I reflected, that was no reason why we should not suspect them--perhaps rather a reason for suspecting.

Senora de Moche was a woman of well-preserved middle age, a large woman, with dark hair and contrasting full, red lips. Her face, in marked contradiction to her Parisian costume and refined manners, had a slight copper swarthiness about it which spoke eloquently of her ancestry.

But it was her eyes that arrested and held one's attention most. Whether it was in the eyes themselves or in the way that she used them, there could be no mistake about the almost hypnotic power that their owner possessed. I could not help wondering whether she might not have exercised it on Don Luis, perhaps was using it in some way to influence Whitney. Was that the reason why the Senorita so evidently feared her?

Fortunately, from our vantage point, we could see without being in any danger of being seen.

"There's Whitney," I heard Craig mutter under his breath.

I looked up and saw the promoter enter from his car. At almost the same instant the roving eyes of the Senora seemed to catch sight of him. He came over and spoke to the de Moches, standing with them several minutes. I fancied that not for an instant did she allow the gaze of any one else to distract her in the projection of whatever weird ocular power nature had endowed her with. If it were a battle of eyes, I recollected the strange look that I had noted about those of both Whitney and Lockwood. That, however, was different from the impression one got of the Senora's. I felt that she would have to be pretty clever to match the subtlety of Whitney.

Whatever it was they were talking about, one could see that Whitney and Senora de Moche were on very familiar terms. At the same time, young de Moche appeared to be ill at ease. Perhaps he did not approve of the intimacy with Whitney. At any rate, he seemed visibly relieved when the promoter excused himself and walked over to the desk to get his mail and then out into the cafe.

"I'd like to get a better view of her," remarked Kennedy, rising. "Let us take a turn or two along the corridor and pass them."

We sauntered forth from our alcove and strolled down among the various knots of people chatting and laughing. As we passed the woman and her son, I was conscious again of that strange feeling, which psychologists tell us, however, has no real foundation, of being stared at from behind.

At the lower end of the lobby Kennedy turned suddenly and we started to retrace our steps. Alfonso's back was toward us now. Again we passed them, just in time to catch the words, in a low tone, from the young man, "Yes, I have seen him at the University. Every one there knows that he is--"

The rest of the sentence was lost. But it was not difficult to reconstruct. It referred undoubtedly to the activities of Kennedy in unravelling mysteries.

"It's quite evident," I suggested, "that they know that we are interested in them now."

"Yes," he agreed. "There wasn't any use of watching them further from under cover. I wanted them to see me, just to find out what they would do."

Kennedy was right. Indeed, even before we turned again, we found that the Senora and Alfonso had risen and were making their way slowly to the elevators, still talking earnestly. The lifts were around an angle, and before we could place ourselves so that we could observe them again they were gone.

"I wish there was some way of adding Alfonso's shoe-prints to my collection," observed Craig. "The marks that I found in the dust of the sarcophagus in the Museum were those of a man's shoes. However, I suppose I must wait to get them."

He walked over to the desk and made inquiries about the de Moches and Whitney. Each had a suite on the eighth floor, though on opposite sides and at opposite ends of the hall.

"There's no use wasting time trying to conceal our identity now," remarked Kennedy finally, drawing a card from his case. "Besides, we came here to see them, anyhow." He handed the card to the clerk. "Senora de Moche, please," he said.

The clerk took the card and telephoned up to the de Moche suite. I must say that it was somewhat to my surprise that the Senora telephoned down to say that she would receive us in her own sitting room.

"That's very kind," commented Craig, as I followed him into the elevator. "It saves planning some roundabout way of meeting her and comes directly to the point."

The elevator whisked us up directly to the eighth floor and we stepped out into the heavily carpeted hallway, passing down to Room 810, which was the number of her suite. Further on, in 825, was Whitney's.

Alfonso was not there. Evidently he had not ridden up with his mother, after all, but had gone out through another entrance on the ground floor. The Senora was alone.

"I hope that you will pardon me for intruding," began Craig, with as plausible an explanation as he could muster, "but I have become interested in an opportunity to invest in a Peruvian venture, and I have heard that you are a Peruvian. Your son, Alfonso, I have already met, once. I thought that perhaps you might be able to give me some advice." She looked at us keenly, but said nothing. I fancied that she detected the subterfuge. Yet she had not tried, and did not try now to avoid us. Either she had no connection with the case we were investigating or she was an adept actress.

On closer view, her eyes were really even more remarkable than I had imagined at a distance. They were those of a woman endowed with an abundance of health and energy, eyes that were full of what the old character readers used to call "amativeness," denoting a nature capable of intense passion, whether of love or hate. Yet I confess that I could not find anything especially abnormal about them, as I had about the eyes of Lockwood and Whitney.

It was some time before she replied, and I gave a hasty glance about the apartment. Of course, it had been rented furnished, but she had rearranged it, adding some touches of her own which gave it quite a Peruvian appearance, due perhaps more to the pictures and the ornaments which she had introduced rather than anything else.

"I suppose," she replied, at length, slowly, and looking at us as if she would bore right through into our minds, "I suppose you mean the schemes of Mr. Lockwood--and Mr. Whitney."

Kennedy was not to be taken by surprise. "I have heard of their schemes, too," he replied noncommittally. "Peru seems to be a veritable storehouse of tales of buried treasure."

"Let me tell you about it," she hastened, nodding at the very words "buried treasure." "I suppose you know that the old Chimu tribes in the north were the wealthiest at the time of the coming of the Spaniards?"

Craig nodded, and a moment later she resumed, as if trying to marshal her thoughts in a logical order. "They had a custom then of burying with their dead all their movable property. Graves were not dug separately. Therefore, you see, sometimes a common grave, or huaca, as it is called, would be given to many. That huaca would become a cache of treasure in time. It was sacred to the dead, and hence it was wicked to touch it."

The Senora's face betrayed the fact that, whatever modern civilization had done for her, it had not yet quite succeeded in eliminating the old ideas.

"Back in the early part of the seventeenth century," she continued, leaning forward in her chair eagerly as she talked, "a Spaniard opened a Chimu huaca and found gold that is said to have been worth more than a million dollars. An Indian told him about it. Who the Indian was does not matter. But the Spaniard was an ancestor of Don Luis de Mendoza, who was found murdered to-day."

She stopped short, seeming to enjoy the surprised look on our faces at finding that she was willing to discuss the matter so intimately.

"After the Indian had shown the Spaniard the treasure in the mound," she pursued, "the Indian told the Spaniard that he had given him only the little fish, the peje chica, but that some day he would give him the big fish, the peje grande. I see that you already know at least a part of the story, anyhow."

"Yes," admitted Kennedy, "I do know something of it. But I should rather get it more accurately from your lips than from the hearsay of any one else."

She smiled quietly to herself. "I don't believe," she added, "that you know that the _peje grande_ was not ordinary treasure. It was the temple gold. Why, some of the temples were literally plated over heavily with pure gold. That gold, as well as what had been buried in the huacas, was sacred. Mansiche, the supreme ruler, laid a curse on it, on any Indian who would tell of it, on any Spaniard who might learn of it. A curse lies on the finding--yes, even on the searching for the sacred Gold of the Gods. It is one of the most awful curses that have ever been uttered, that curse of Mansiche."

Even as she spoke of it she lowered her voice. I felt that no matter how much education she had, there lurked back in her brain some of the primitive impulses, as well as beliefs. Either the curse of Mansiche on the treasure was as real to her as if its mere touch were poisonous, or else she was going out of her way to create that impression with us.

"Somehow," she continued, in a low tone, "that Spaniard, the ancestor of Don Luis Mendoza, obtained some idea of the secret. He died," she said solemnly, flashing a glance at Craig from her wonderful eyes to stamp the idea indelibly. "He was stabbed by one of the members of the tribe. On the dagger, so I have heard, was marked the secret of the treasure."

I felt that in a bygone age she might have made a great priestess of the heathen gods. Now, was she more than a clever actress?

She paused, then added, "That is my tribe--my family."

Again she paused. "For centuries the big fish was a secret, is still a secret--or, at least, was until some one got it from my brother down in Peru. The tradition and the dagger had been intrusted to him. I don't know how it happened. Somehow he seemed to grow crazy--until he talked. The dagger was stolen from him. How it happened, how it came into Professor Norton's hands, I do not know.

"But, at any rate," she continued, in the same solemn tone, "the curse has followed it. After my brother had told the secret of the dagger and lost it, his mind left him. He threw himself one day into Lake Titicaca."

Her voice broke dramatically in her passionate outpouring of the tragedies that had followed the hidden treasure and the Inca dagger.

"Now, here in New York, comes this awful death of Senor Mendoza," she cried. "I don't know, no one knows, whether he had obtained the secret of the gold or not. At any rate, he must have thought he had it. He has been killed suddenly, in his own home. That is my answer to your inquiry about the treasure-hunting company you mentioned, whatever it may be. I need say no more of the curse of Mansiche. Is the Gold of the Gods worth it?"

There could be no denying that it was real to her, whatever we might think of the story. I recollected the roughly printed warnings that had been sent to Norton, Leslie, Kennedy, and myself. Had they, then, some significance? I had not been able to convince myself that they were the work of a crank, alone. There must be some one to whom the execution of vengeance of the gods was an imperative duty. Unsuperstitious as I was, I saw here a real danger. If some one, either to preserve the secret for himself or else called by divine mandate to revenge, should take a notion to carry out the threats in the four notes, what might not happen?

"I cannot tell you much more of fact than you probably already know," she remarked, watching our faces intently and noting the effect of every word. "You know, I suppose, that the treasure has always been believed to be in a large mound, a tumulus I think you call it, visible from our town of Truxillo. Many people have tried to open it, but the mass of sand pours down on them and they have been discouraged."

"No one has ever stumbled on the secret?" queried Kennedy.

She shook her head. "There have been those who have sought, there are even those who are seeking, the point just where to bore into the mounds. If they could find it, they plan to construct a well-timbered tunnel to keep back the sand and to drive it at the right point to obtain this fabulous wealth."

She vouchsafed the last information with a sort of quiet assurance that conveyed the idea, without her saying it directly, that any such venture was somehow doomed to failure, that desecrators were merely toying with fate.

All through her story one could see that she felt deeply the downfall and betrayal of her brother, followed by the tragedy to him after the age-old secret had slipped from his grasp. Was there still to be vengeance for his downfall? Surely, I thought to myself, Don Luis de Mendoza could not have been in possession of the secret, unless he had arrived at it, with Lockwood, in some other way than by deciphering the almost illegible marks of the dagger. I thought of Whitney. Had he perhaps had something to do with the nasty business?

I happened to glance at a huge pile of works on mining engineering on the table, the property of Alfonso. She saw me looking at them, and her eyes assumed a far-away, dreamy impression as she murmured something.

"You must know that we real Peruvians have been so educated that we never explore ruins for hidden treasure, not even if we have the knowledge of engineering to do so. It is a sort of sacrilege to us to do that. The gold was not our gold, you see. Some of it belongs to the spirits of the departed. But the big treasure belonged to the gods themselves. It was the gold which lay in sheets over the temple walls, sacred. No, we would not touch it."

I wondered cynically what would happen if some one at that moment had appeared with the authenticated secret. She continued to gaze at the books. "There are plenty of rare chances for a young mining engineer in Peru without that."

Apparently she was thinking of her son and his studies at the University as they affected his future career.

One could follow her thoughts, even, as they flitted from the treasure, to the books, to her son, and, finally, to the pretty girl for whom both he and Lockwood were struggling.

"We are a peculiar race," she ruminated. "We seldom intermarry with other races. We are as proud as Senor Mendoza was of his Castilian descent, as proud of our unmixed lineage as any descendant of a 'belted earl.'"

Senora de Moche made the remarks with a quiet dignity which left no doubt in my mind that the race feeling cut deeply.

She had risen now, and in place of the awesome fear of the curse and tragedy of the treasure her face was burning and her eyes flashed.

"Old Don Luis thought I was good enough to amuse his idle hours," she cried. "But when he saw that Alfonso was in love with his daughter, that she might return that love, then I found out bitterly that he placed us in another class, another caste."

Kennedy had been following her closely, and I could see now that the cross-currents of superstition, avarice, and race hatred in the case presented a tangle that challenged him.

There was nothing more that we could extract from her just then. She had remained standing, as a gentle reminder that the interview had already been long.

Kennedy took the hint. "I wish to thank you for the trouble you have gone to," he bowed, after we, too, had risen. "You have told me quite enough to make me think seriously before I join in any such undertaking."

She smiled enigmatically. Whether it was that she had enjoyed penetrating our rather clumsy excuse for seeing her, or that she felt that the horror of the curse had impressed us, she seemed well content.

We bowed ourselves out, and, after waiting a few moments about the hotel without seeing Whitney anywhere, Craig called a car.

"They were right," was his only comment. "A most baffling woman, indeed."

VII

THE ARROW POISON

Back again in the laboratory, Kennedy threw off his coat and plunged again into his investigation of the blood sample he had taken from the wound in Mendoza's body.

We had scarcely been back half an hour before the door opened and Dr. Leslie's perplexed face looked in on us. He was carrying a large jar, in which he had taken away the materials which he wished to examine.

"Well," asked Kennedy, pausing with a test-tube poised over a Bunsen burner, "have you found anything yet? I haven't had time to get very far with my own tests yet."

"Not a blessed thing," returned the coroner. "I'm desperate. One of the chemists suggested cyanide, another carbon monoxide. But there is no trace of either. Then he suggested nux vomica. It wasn't nux vomica; but my tests show that it must have been something very much like it. I've looked for all the ordinary known poisons and some of the little-known alkaloids, but, Kennedy, I always get back to the same point. There must have been a poison there. He did not die primarily of the wound. It was asphyxia due to a poison that really killed him, though the wound might have done so, but not quite so quickly."

I could tell by the look that crossed Kennedy's face that at last a ray of light had pierced the darkness. He reached for a bottle on the shelf labelled spirits of turpentine.

Then he poured a little of the blood sample from the jar which the coroner had brought into a clean tube and added a few drops of the spirits of turpentine. A cloudy, dark precipitate formed. He smiled quietly, and said, half to himself, "I thought so."

"What is it?" asked the coroner eagerly, "nux vomica?"

Craig shook his head as he stared at the black precipitate. "You were perfectly right about the asphyxiation, Doctor," he remarked slowly, "but wrong as to the cause. It was a poison--one you would never dream of."

"What is it?" Leslie and I asked simultaneously.

"Let me take all these samples and make some further tests," he said. "I am quite sure of it, but it is new to me. By the way, may I trouble you and Leslie to go over to the Museum of Natural History with a letter?"

It was evident that he wanted to work uninterrupted, and we agreed readily, especially because by going we might also be of some use in solving the mystery of the poison.

He sat down and wrote a hasty note to the director of the Museum, and a few moments later we were speeding over in Leslie's car.

At the big building we had no trouble in finding the director and presenting the note. He was a close friend of Kennedy's and more than willing to aid him in any way.

"You will excuse me a moment?" he apologized. "I will get from the South American exhibit just what he wants."

We waited several minutes in the office until finally he returned carrying a gourd, incrusted on its hollow inside surface with a kind of blackish substance.

"That is what he wants, I think," the director remarked, wrapping it up carefully in a box. "I don't need to ask you to tell Professor Kennedy to watch out how he handles the thing. He understands all about it."

We thanked the director and hurried out into the car again, carrying the package, after his warning, as though it were so much dynamite.

Altogether, I don't suppose that we could have been gone more than an hour.

We burst into the laboratory, but, to my surprise, I did not see Kennedy at his table. I stopped short and looked around.

There he was over in the corner, sprawled out in a chair, a tank of oxygen beside him, from which he was inhaling laboriously copious draughts. He rose as he saw us and walked unsteadily toward the table.

"Why--what's the matter?" I cried, certain that m our absence an attempt had been made on his life, perhaps to carry out the threat of the curse.

"N-nothing," he gasped, with an attempt at a smile. "Only I--think I was right--about the poison."

I did not like the way he looked. His hand was unsteady and his eyes looked badly. But he seemed quite put out when I suggested that he was working too hard over the case and had better take a turn outdoors with us and have a bite to eat.

"You--you got it?" he asked, seizing the package that contained the gourd and unwrapping it nervously.
