Chapter II: Part 2

The weather was fine and we made almost a record trip in point of time. There was nothing for Odell to regret in the briefness of the voyage, for Grace Callender remained in her cabin till he sent a message by her aunt, promising not to try for a word or a look if she came on deck. After that she appeared again, as if to show appreciation, and Odell didn't abuse her confidence. He kept himself to the other side of the deck; but there was no reason why I should give up my place near the two ladies. After the first night's dinner _en tete-a-tete_, Odell and I had no more meals together; consequently, the Misses Callender, aunt and niece, were unaware of our acquaintanceship. They had no reason to shun their lame neighbour, and my crutches gave me their sympathy, as they have given me various other blessings. Instead of my picking up a dropped book, as a man usually contrives to do if he yearns to know a girl on shipboard, Grace Callender retrieved one for me. After that, I was permitted, even encouraged, to draw my deck-chair closer to theirs and "tell them things about the war." I noticed that the girl caught eagerly, nervously, at any subject which could hold her attention for a moment, even that of my book and Carr Price's play. I, having the secret clue, guessed that she was for ever trying to escape from a thought too engrossing. Her aunt, Miss Marian Callender, had the clue also; and often I caught her long dark eyes--eyes like those of La Gioconda--fixed with almost painful intentness on Grace. "She knows that her niece is thinking about Odell," I told myself. Evidently she approved the girl's decision to put him out of her life. If she had been Odell's friend and sympathiser, a woman of her superior age and strong personal charm (for she had a sort of hypnotic charm, like a velvet-petalled flower with a penetrating perfume) could surely have influenced an impressionable girl, especially one so devoted to her as Grace Callender was.

It was nine o'clock on an April morning when we escaped from the custom-house men and spun away from the White Star docks in a glittering grey car. When I say "we," I refer to myself and the two Misses Callender. They had befriended me to the extent of recommending me to an hotel and offering to motor me to it; and I was malicious enough to hope that Odell might see me going off with them. There was little doubt in my mind that he did so, and none at all of what feelings must have been roused by the sight. These would have been still more poignant had he known that it was Grace who impulsively invited me, Marian who merely followed with a polite echo. They lived in a large old-fashioned house in Park Avenue, where the car dropped the ladies and by their order took me on to the Hotel Belmont. There Carr Price was waiting, for when--the day before our landing--the Callenders had mentioned the Belmont I marconied him to meet me at the hotel.

"Why did you wire 'Don't come to the dock?'" he asked almost resentfully.

"Because I thought it might annoy Roger Odell if I dangled you under his nose," I explained.

"Roger Odell's nose!" Price gasped. "Where--where----"

"Was it? On the _Monarchic_. And I didn't pull it; neither did he pull mine. I even have hopes that the two features may come to terms. To-morrow, at exactly this hour, you're due to know why. But meanwhile I want you to promise me patience, blind faith and--unquestioning help. There's no time to waste over it, so here goes! Who's the most influential man you know in New York?"

"George Gould," he said.

"Pooh! a mere millionaire. He's no use to me. Do you know anyone in the police force--high enough up to do you a favour?"

Price pondered for an instant. "I know Sam Yelverton. Is that name familiar to you?"

"It is. Think we'll find him in now if you take me to call?"

"If this is our lucky day we shall."

"Let's put it to the test. I've noticed that New York has taxis as well as London."

"And you'll notice the difference when you've paid for one. But this is on me."

The omen of luck was good, for we found our man at the police head-quarters, and, true to his promise, Carr Price sat as still and expressionless as an owl while I did the talking. I had been introduced to the great Sam Yelverton by my own request as the author of _The Key_, and it really was a stroke of luck that he had read and liked it. He looked interested when I said that I'd got an idea for my book from a _cause celebre_ in New York--"The Callender-Graham affair," I explained.

"Ah, the latchkeys in the dead men's pockets!" he caught me up.

"Exactly. Now it's a question of a play by Mr. Price, on the same lines as my book and with the same title, soon, _very_ soon, to be produced at the Felborn Theatre. It will be of the greatest assistance to him and to me in working out an important detail if I can have Ned Callender-Graham's latchkeys--anyhow, the smaller one--in my hands for a few hours to-day. Indeed, I'm afraid we can't get much 'forrarder' if you refuse."

(This was the literal truth, for, unless I could obtain the more important of those two keys and do with it what I hoped to do, I should be unable to "deliver the goods" to Roger Odell. I should stand with him where I had stood before the "hold up" interview, and the play would be pigeon-holed indefinitely. Price's eyes were starting from his head, but he kept his tongue between his teeth.)

Mr. Yelverton seemed amused. "I guess I may be able to manage that," he said, "if one or both of those keys are still in our hands, as I believe they are. If I do the trick for you I'll expect a box for the play on the first night, eh?"

"It's a bargain, isn't it, Carr?" said I.

The dazed Price assented.

"Oh, and by the way, Mr. Yelverton"--I arrested the famous man as he picked up the receiver of his desk telephone--"if the letters and the empty envelopes found on the bodies of the two brothers are still among your police archives, would it be possible for me to have a look at them?"

Yelverton--a big man with a red face and the keenest eyes I ever saw, deep set between cushiony lids--threw me a quick glance. "You do remember the details of that case pretty well, Lord John!" he said.

"I'm an amateur follower in your famous footsteps," I reminded him. He smiled, called up a number and began telephoning. I admired the clear way in which he put what he wanted--or what I wanted--without wasting a word. He asked not only for the keys, but for the whole dossier in the double case of the Callender-Graham brothers. Then came a moment of waiting in which my heart ticked like a clock; but I contrived to answer Mr. Yelverton's mild questions about our weather on shipboard. At last a sharp ring heralded an end of suspense.

"Sorry, Lord John," the big man began, taking the receiver from the generous shell of his ear. "They're sending round the dossier, but our chaps have got none of the Callender-Graham 'exhibits in their possession--haven't had for nearly a year. I feared it was likely to be so. You see, there was no proof that any crime had been committed on either of the two brothers; in fact, the theory was against it. When the police definitely dropped the case--or cases--the family was entitled to all personal property of the deceased. Everything found on the body of Ned Callender-Graham was handed over to the relatives by their request, as had been done a few weeks after the elder brother's death, even the letters and those empty envelopes you were intelligent enough to single out for observation. We had done the same, naturally, but, in every sense of the word"--he grinned--"there was nothing in 'em."

"The keys on Ned's body were handed over to the Misses Callender, then?" I inquired, stiffening the muscles of my face to mask my disappointment.

"Yes. Perhaps, as you remember so much, you recall the fact that the first two keys were given to the relatives. Miss Marian Callender and her niece believed that Ned had Perry's keys in his pocket, which would mean there were but the two. The Callender ladies are the sole surviving relatives, or, anyhow, the nearest ones. But I've saved my bit of good news from head-quarters till the last. They 'phoned that there are duplicate keys. I thought I recalled something of the sort. Not sure but I suggested making them myself. That pretty millionairess girl might get herself engaged a third time, and if there were any more dead men found with latchkeys in their pockets, sample specimens might be very handy for our fellows."

Sam Yelverton finished with a laugh; but I couldn't echo it. I thought of Odell, of Grace Callender's lovely face and her young, spoilt life. I remembered the cruel nicknames "Belladonna" and "Poison Flower." If even the police prepared for a third tragedy, in case she thought again of marriage, no wonder the poor girl refused the man she loved.

"Will duplicates do for you, or do I lose my stage-box?" the big man asked.

I said aloud that I thought duplicates would answer my purpose, and silently to myself I said that they must do so.

Ten minutes later a policeman of some rank (what rank I couldn't tell, he being my first American specimen) brought in a parcel of considerable size. It contained many affidavits concerning the Callender-Graham tragedy; and on the top of these documents was a small, neatly labelled packet containing two keys.

The larger was entirely commonplace; and even the smaller one was at first glance a rather ordinary latchkey, of the Yale order. To an experienced and observant eye, however, it was of curious workmanship.

"Not a Yale, you see," said Yelverton, taking a magnifying glass from a small drawer of his tidy desk and passing it on to me. "What do you make of the thing?"

"Foreign, isn't it?" I remarked carelessly.

"Yes, we thought so. German--or Italian. Both the brothers had travelled abroad. On a Yale you would read the words 'Yale paracentric,' and a number. There's neither name nor number on that." He flung a gesture toward the key in my hand.

"May I take it away and keep it till to-morrow morning, to work out my plot with?" I asked. "The big one I don't care about. I give you my word I'll send this back in twenty-four--no, let's say twenty-five hours. I have an engagement for the twenty-fourth hour."

"All right," replied Yelverton good-naturedly. "You might bring the box-ticket with you. Ha, ha!"

"I will," I laughed. "And as to the dossier, may I sit somewhere out of your way and glance through it in case there's anything we can work up to strengthen the realism of our scenario? Of course, we'll guarantee to use nothing that might recall the Callender-Graham case to the public or dramatic critics."

"You can sit in the outer office and browse over the bundle till lunch-time, if you like," said Yelverton. "There's a table there in a quiet corner. I shall be off on business before you finish, I expect. See you later--at the Felborn Theatre, your first night. Wish you luck."

I thanked him and got up. Carr Price followed suit.

"Weren't you a bit premature mentioning the Felborn?" he reproached me in the next room, beyond earshot of Mr. Yelverton's secretaries and stenographers.

"No," I reassured him. "To-morrow, at this time or a little later, you'll know why. Meanwhile, don't worry, but take my word--and a taxi to the theatre. Tell Felborn I'm on the spot, and there's a truce between Odell and me, an armistice of twenty-four"--I pulled out my watch--"no, twenty-two and a half hours. Ask him to lend me his private office to-morrow morning from nine till ten o'clock. After that time you and he had better hold yourselves ready to be called in to discuss dates."

"You're either the wonder child of the British Empire or its champion fool," remarked Price somewhat waspishly, as he prepared to leave me alone with the Callender-Graham dossier.

"You've got till to-morrow to make up your mind which," said I, sitting down to my meal of manuscripts in order not to waste a minute out of the twenty-two and a half hours which remained to me. It would not have been wise to add that I didn't know which myself.

Many of the papers I passed over rapidly. Others gave me information that I couldn't have got from Odell without a confession of ignorance, or from the Misses Callender without impertinence. Among the latter was one summarising much of the family history; and, profiting by some smart detective's researches, I learned a good deal about Miss Grace Callender and her almost equally interesting aunt.

Even before the girl reached the age of sixteen, it seemed, she had begun to have offers of marriage. After her parents' death, when she was not quite fifteen, she had lived for a while with Miss Marian Callender at the house in Park Avenue left to her by her father. She had been taught by French governesses, German governesses and English governesses, but all had failed to prevent a kind of persecution by young men fascinated with the child's beauty or her money. At last Miss Callender senior had sent her niece to a boarding-school in the country where the supervision was notoriously strict, and had herself gone to Italy, her mother's native land, for a few months' visit. Eight or nine years before this Marian Callender had fallen in love with an Italian tenor, singing with enormous success in New York. The lady's half-brother--Grace's father--had objected to the marriage, and for that reason or some other the two had parted. Gossips said that the singer, Paolo Tostini, had not cared enough for Marian Callender to take her without a _dot_; and all she had came from her millionaire half-brother. At Graham Callender's death Marian's friends were surprised that she was left a yearly allowance (though a magnificently generous one) only while she "continued unmarried and acted as Grace's guardian." In the event of Grace's marriage, the girl was free to continue half the same allowance to her aunt if she chose. This was generally considered unjust to Marian, and the only excuse for the arrangement seemed to be that Graham Callender feared Paolo Tostini might come forward again if the woman he had jilted were left with a fortune.

The police of New York had apparently thought it worth while to ferret out further facts in connection with the singer, who had not again returned to America. They learned that the once celebrated tenor had lost his voice and had spent his money in extravagance, as many artists do. He was living in comparative poverty with his father (a skilled mechanician and inventor of a successful time lock for safes) and his younger brother in Naples at the time of Miss Marian Callender's visit to Italy, and Grace's school life. Although these facts were inquired into only after some years had passed, and the two brothers Callender-Graham had died, Marian's movements must have been easily traced, for it was learned that she had openly visited the Tostinis at their small villa between Posilipo and Naples. The family had also called and dined at her hotel, where they were not unknown. After that their circumstances had apparently improved, and it appeared not improbable that Marian Callender had helped her late lover's people.

When she returned to New York it was to find that Grace was being bombarded with love letters at school, and that the hotel in the village near by had for its principal clients a crowd of young men whose whole business in life was lying in wait for the heiress. In consequence, Marian brought her niece back to the house in Park Avenue; and soon after, before the girl had been allowed to come out in society, Antonio, the younger brother of Paolo Tostini, arrived in New York. His business was that of an analytical chemist. He had first-rate recommendations, and was an extremely brilliant, as well as singularly good-looking young man, some (who remembered the tenor) thought even handsomer than Paolo. Antonio Tostini, thanks to his own ability and the introductions he had from Miss Callender and others, got on well both in business and society. No one was surprised, and no one blamed her, when Marian Callender threw the clever young Italian and Grace Callender together--except that the girl was young to make up her mind, and her dead father had favoured a match with one of the disinherited cousins.

From these rough notes, crudely classifying Antonio Tostini's courtship of Grace Callender, I gathered that the young Italian had fallen desperately in love with the girl. He had assured friends whom they had in common that even if, to marry him, she were obliged to give up her fortune, he would still think himself the happiest man on earth to win her. Grace's aunt, who had tried to keep the girl out of other men's way, evidently favoured her old love's brother. She chaperoned a yachting party, of which Grace and Antonio were the most important members, a party in which the Callender-Grahams were not included, though they wished for invitations. This match-making effort on Marion's part stifled all suspicion that she discouraged Grace from marrying in order to retain a charming home, a large, certain income, and all kinds of other luxuries for herself. She had taken Grace's refusal of Antonio Tostini almost as hard as he had taken it himself. She had even been ill for several weeks when for the third time Grace had sent him away, and he returned in despair to Italy. It was not long after this affair (the dossier informed me) that, in accordance with her father's desire, the girl engaged herself to Perry Callender-Graham, and Marian consented to the inevitable. Her affection and support during the tragic experiences that followed had given great comfort to Grace, and, so far as was known, Antonio Tostini had had the good taste never to appear on the scene again.

Here were many details which I had been anxious, but not decently able, to learn, as the Misses Callenders' shipboard friendship had confined itself to lending me books, telling me what to do in New York, inviting me to call, listening to talk about the war or the play, and allowing me to snapshot them on deck.

Having looked through the dossier, I took my departure with the key. It was only a duplicate, yet I couldn't rid myself of a queer, superstitious feeling for the thing, as if it were offered to me by the unseen hand of a dead man.

I taxied back to my hotel and mentioned to a clerk that I wanted to see houses and flats in the direction of Riverside Drive. Could he direct me to an agent who would have the letting of apartments in that neighbourhood? If my foreign way of expressing myself amused him, he hid his mirth and looked up in a big book the addresses of several agents.

I had not cared to be too specific in my questions, but I chose the address nearest the street I wanted, taxied there, found the agent, and inquired if there were anything to be let. It was the street in which Perry Callender-Graham and Ned, his brother, had met their death.

"I have been recommended to that particular street by an American friend in England," I said. "He has told me that it's very quiet. There are several apartment houses in it, are there not?

"Yes," replied a spruce young man who looked willing to let me half residential New York. "But it's a favourite street; I'm afraid there's nothing doing there now. As for houses, they're all owned, or have been rented for many years. A little farther north or south----"

"Hold on," I pulled him back. "Somebody might be induced to let. My friend was telling me about a charming flat--oh, apartment you call it?--in that street which a friend of _his_ took---let me see, it must have been three years ago or thereabouts. Anyhow, not later. He had reason to believe I might get that very flat. Stupid of me! I can't remember the number or name--whichever it was--of the house. I know the flat was a furnished one, however; and if your agency----"

"Oh, if the apartment was furnished, and changed hands three years ago, there's only one it _could_ be, if you're sure it's in that street?"

"I'm sure," I replied. I staked all on that sureness, though logically---- But I would not let my mind wander to any other deduction than the one to which, for better or worse, I pinned my faith.

"We had the letting of a furnished apartment in the Alhambra, as the house is named, put into our hands three years ago on the 30th of last month," said the youth, referring to a book. "To my certain knowledge no other furnished one was to be had in the street at that time, and there hasn't been since. Isn't likely to be either, so far as I can see. That was the grand chance. German-American lady and gentleman, Mr. and Mrs. Maurice Lowenstein, going unexpectedly to Europe, and glad to get rid of their apartment to a good tenant at a nominal price."

"You found the good tenant?" I asked.

"We did, sir--or the tenant found us. Wanted a furnished apartment, not too large or expensive, in a quiet street, quietness the great consideration. Above all, the proprietors mustn't want to use the place again for at least five years. That just fitted in, because our clients were anxious to let for seven years; the husband had a business opening in Hamburg. The new tenant took the place for that period; and as there's a long time to run yet, I shouldn't have thought there was much hope for you. However, your friend may have private information."

"Does the new tenant live there altogether?" I wanted to know.

"Only comes up from the country occasionally. Expensive fad, to rent a New York apartment that way. But what's money _for_? Some people have it to burn."

"Quite so," I admitted. "Have you ever met the tenant?"

"Only once--when the apartment was engaged; fixed up in one interview. The rent comes through the post."

"It must be the apartment my friend talked about!" I exclaimed.

"Can't be any other. Is the name of your friend's friend Paulling?"

"Why, yes, I have the impression of something like that. By the way, I might be able to find an old photograph, to make quite sure. Would you recognise it?"

"I might--and I mightn't. Three years is a long time."

"Well, I'll do my best through some acquaintances," I finished. "If we're speaking of the same person, you may be able to introduce me and save the delay of communicating with my friend in England."

Each was flattering himself on his discretion, the whole catechism having been gone through without the question on either side, "Is the person a man or a woman?" Eventually we parted with the understanding that I should return later if, after looking at the Alhambra from the outside, I fancied it as much as I expected to do. And then I was to bring the photograph with me.

So far so good. But the next steps were not so simple.

I stopped my taxi at the corner (not to advertise myself with unnecessary noise) and limped the short distance which Perry Callender-Graham and his brother Ned must have travelled on the secret errands that led them to their death. The Alhambra was neither as picturesque nor as imposing as its name suggested. It was just a substantial brick building, six or seven storeys in height, with facings of light-coloured stone, and large, cheerful windows. Luckily for my lame leg, the entrance was but a step above the street level. As I arrived the door was opened by a chocolate-brown negro in chocolate-brown livery. He helped a smart nurse to pass out with a baby in a white and gold chariot, and while he was thus engaged I hobbled into the hall. A hasty glance at a name board on the wall opposite gave me the list of occupants and the floor on which each tenant lived. Evidently there were two flats to each storey. T. Paulling had an apartment on the third, so also had G. Emmett. I had to risk something, and so when the brown hall-porter turned to me (which he did with embarrassing swiftness) I risked inquiring for Mr. Emmett. I believed, I added, that he was expecting me.

"That's all right, sir. He's in," was the welcome reply, with a compassionate grin at the crutches which guaranteed the harmlessness of an unknown visitor. "I'll take you in the elevator."

Up we shot to the third floor, where I feared that my conductor might insist on guiding me to the door of Mr. Emmett. Fortunately, however, someone rang for the lift and the porter shot down again, directing me to the right.

The instant he was out of sight I turned to the left, and, with the police key in my hand, I stood before the door of T. Paulling.

My blood leaped through my veins, and the hand that tried the key in the lock shook with the rush of it. I heard its pounding in my ears, and through the murmurous sound the question whispered, "What if the key won't fit? Down goes the whole theory. You'll have to confess yourself a fool to Roger Odell."

As I blundered at the lock in haste and fear that someone might pass, or that this might be one of T. Paulling's rare days at the flat, I was aghast at my late self-confidence. Face to face with the test, it seemed impossible that my-boast to Odell and Carr could succeed. I felt callow and stupid, altogether incompetent. The key seemed too large and the wrong shape, which meant that the mystery of the brothers' death was closed to me, like the door. A voice not far off made my nerves jump, and--the key slipped into the lock! From somewhere above or below came the sound of voices, but I could not be seen from the lift. Almost before I knew what I was doing or what had happened, I was on the other side of the door, in a dark and stuffy vestibule.

The sound of voices was suddenly stilled. It was as if with a single step I had won my way into another world. I drew a long breath of relief after the strain, for the silence and darkness said that the tenant was not at home, and I might hope to have the flat to myself.

I groped for an electric switch, touched it, and flooded the vestibule with light. It was small, with nothing to distinguish it from any other vestibule of any other well-furnished flat. Beyond led a narrow corridor which, when lit, showed me several doors. I opened the nearest, switched on another light, and found myself on the threshold of a moderate-sized sitting-room or study, with bookshelves ranged along one of the walls. The window was so heavily curtained that I had no fear of the sudden illumination being noticed from the street. The air was heavy and smelled of moth powder. The mahogany table in the centre of the room and the desk under the window were coated with thin films of dust, but everything was stiffly in order: no books lying about, no woman's work, no trace of cigarette ash, dropped glove, nor pile of newspapers with a tell-tale date.

I walked over to the desk and, pulling out the swivel chair, sat down. In the silver inkstand the ink had dried. In a pen-rack were two pens, one stub, the other an old-fashioned quill, both almost new, but faintly stained with ink. Neither, it struck me, could have been used more than once or twice. There were several small drawers; all were empty. No paper nor envelopes, no sealing-wax nor seal, not so much as an end of twine. But the blotting-pad--the only movable thing on the desk beside the inkstand and pen-rack--was more repaying. It also appeared to be nearly new. Just inside the soft green leather cover lay two sheets of plain, unmonogrammed grey-blue paper with two envelopes to match. I annexed one of the latter and made a mental note that, in the police dossier of the Callender-Graham case the empty envelope found in the pocket of the younger brother was said to be blue-grey in colour and of thick texture. No record had been kept concerning the colour of the envelope in Perry's pocket, as little importance had been attributed to it, until the coincidence of the second envelope was remarked later.

The blotting-pad was as new-looking as the pens. The two uppermost sheets were of unspotted white, but the middle pages had both been used, and traces were visible of two short notes having been pressed against the paper while the ink was still very wet. Apparently these documents had had neither heading nor signature, and consisted of a few lines only. On another page a longer letter began "Dearest," and had been signed with an initial. There was no mirror in the room in which to reverse these writings, and, carefully separating the used sheets from their unsoiled fellows, I folded and slipped them into an inner pocket. There was nothing else in the room which could help me, with the exception, perhaps, of the books; and most of these were in sets, bound in a uniform way. These had a book-plate and the monogram "M.L.," no doubt meaning Maurice Lowenstein. Of new novels or other publications there were none: an additional proof (if it had been needed after the clue of the dried ink and almost unused blotter) that the new tenants were seldom in the place.

Having deduced this fact, I then went through the remaining six rooms of the flat without any discoveries, and finally reached, in its due order, the problem I had left for the last. This was the examination of the lock which the dead brothers' latchkeys had fitted. The work had to be done with the door open, and therefore I waited until the hour when most people lunch. It would look like burglarious business, what I had to do, and it was important not to be interrupted or arrested.

The hands of my watch were at one o'clock as mine were on the latch which, if I were right, could with a single click solve the Callender-Graham mystery. If I were wrong, not only were four out of my twenty-four hours wasted, but my theory fell to the ground and broke into pieces past mending.

I opened the door of the flat and made sure that, for the moment, no one was in the hall. Then, bending down with my back to possible passers-by, I whipped out a magnifying glass and pocket electric torch which I had bought on my way to the agent's.

During the next five minutes I had good cause to thank Heaven for the mechanical bent that had turned my mind to motors and aeroplanes.

The same evening, at a little after six, a "commuter's" train landed me at the station of a small Long Island town almost too far away from New York to be labelled suburban. Big automobiles and small runabouts were there to meet the tired business men who travelled many miles for the sake of salt breezes and the latest thing in Elizabethan houses. I was more tired than any business man; also, I had encountered as many setbacks as successes, but nobody and nothing came to welcome me. I was able, however, to get a place in an old-fashioned horse-drawn vehicle whose mission was to pick up chance arrivals. There were several of us, and as my rate of locomotion was slow, by the time I had hobbled off the platform the one seat left was beside the driver. I was not sorry, as the other men appeared to be strangers in Sandy Plain, and having said I would go to the hotel (for the sake of saying something), I asked my companion if he knew anybody named Paulling.

"There's two families of that name hereabouts," he replied.

"My Paullings," I hazarded, "are retiring people, don't make friends, and are away a good deal."

"Ah, they'd be the Paullings of Bayview Farm!" returned the driver. "There's no others answer that description around here that I ever heard of, and I've lived at Sandy Plain since before the commuters discovered it."

"Yes, I mean the Paullings of Bayview Farm," I caught him up.

"The farm's about a mile and a half past Roselawn Hotel," my seat mate went on. "I can take you there after I drop the other folks."

I thanked him and said he might come back for me if he cared to after I had dined, and inquired casually if the Paullings were staying at their farm just then.

The driver shook his head. He didn't know. Few persons did know much about the Paullings, who weren't old residents, but had rented Bayview Farm two or three years ago. Maybe the hotel folks might be able to tell me whether I was likely to find them.

They could not do so, I soon learned. Mr. Paulling was said to be an invalid, though he never called in the local doctor. He was often at home alone for weeks together, except for a man-servant, a foreigner as reserved as himself, whom he had brought with him to Sandy Plain. There was another servant sometimes--a woman--also a foreigner; but when the Paullings were both away a Mrs. Vandeermans, a country dressmaker who lived in a cottage near by, looked after the house, going in occasionally to see that all was well.

I asked as many questions as I dared, but learned little; and as soon as dusk had begun to fall I started off in the nondescript vehicle which had returned for me. The driver spent most of the twenty minutes it took him to reach the farm in explaining that it wasn't really a farm except in name. Nothing was left of it but the house and two or three acres of orchard; all the rest had been sold off in lots by the owner before he let it to the Paullings. What "city folks" admired in it was beyond the knowledge of my companion, but when we arrived at the gate and saw the far-off house gleaming white behind a thick screen of ancient apple trees, I realised the attractions of the place, especially for such tenants as I believed the Paullings to be. The farm-house, with its wide clapboarding, its neat green shutters, and its almost classic "colonial" porch hung with roses, had the air of being on terms of long familiar friendship with the old-fashioned garden and the great trees which almost hid it from its neighbours and the road. Its front windows, closed and shuttered now, would look out when open over sloping lawns and flowerbeds to distant blue glints of the sea; and altogether Bayview Farm seemed an ideal retreat for persons who could be sufficient to themselves and each other.

Those shuttered windows, however, hinted at disappointment for me. Not a light showed, behind one of them, and when I had rung the bell of the front door, and pounded vainly at the back, I had to make up my mind that the Paullings were either away or determined to be thought so. "Mrs. Vandeermans 'll know all about 'em," my conductor comforted me. "She lives next door, a quarter of a mile farther on."

We drove the quarter mile, only to be struck by another blow. The one person at home in Mrs. Vandeermans' cottage was that widowed woman's mother, very old, very deaf, half blind, knowing little about anything, and nothing at all about the tenants of Bayview Farm.

"My darter's gone to my son's in Buffalo," she quavered when I had screamed at her. "He's sick, but she'll be back to-morrow to look after me. She knows them Paullings. You come again to-morrow afternoon if you want to talk to her."

"You seem sure disappointed," remarked my companion, as he drove me and my crutches back to Roselawn Hotel.

"I am," I admitted; but the words were as inadequate as most words are. I was bowled over, knocked out, or so I told myself in my first depression. Nothing was of any use to me after to-morrow morning at nine o'clock.

On my way back to New York in a slow train I gloomily thought over the situation. Certain startling yet not unexpected discoveries made early in the day had elated me too soon. I had collected evidence, but only circumstantial evidence. I had no absolute proof to give Roger Odell, and nothing less would suffice. I had counted on getting hold of proof at Sandy Plain, from which place on Long Island (I had learned from the agent) cheques came regularly each quarter to pay the rent of the flat in the Alhambra--cheques sometimes signed T. Paulling, sometimes M. Paulling. One had arrived only a few days before with the former signature, so I had reason to hope that T. Paulling might be unearthed at Sandy Plain.

I could, I told myself, write to Roger Odell and ask for a delay, but that would kill such feeble faith in me as I had forcibly implanted in him. He would think me a fraud, and believe that I had been trying to gain time in order to spring some trick upon him. Besides, the Paullings might come to New York, if they were not already there, and discover that some person unknown was on their track and had been tearing sheets out of their blotting-book. No, I must keep my appointment with Roger Odell or face the prospect of complete failure. But how to convince him of what I was myself convinced, with the disjointed bits of evidence in my possession? Just as my train came to a stop with a slight jolt in the Pennsylvania station, I saw as in an electric flash a way of doing it. Perhaps it was the jolt that gave the flash.

I could not wait to get back to my hotel. I inquired of a porter where I could get a messenger boy. He showed me. I begged two sheets of paper and two envelopes. They were pushed under my hand. I scratched off six lines to Roger Odell: "Don't think when you get this I'm going to ask you to put off our interview. On the contrary, I ask you to advance it. Please be in Julius Felborn's private office at a quarter to nine instead of nine. This is vitally important. If he has a large safe in his office, get the key or combination so that you can open it. Small safe no use.--Yours hopefully, J.H."

I finished this scrawl and sent it away by messenger to the club where Odell had said I might 'phone, if necessary, up to one o'clock that night. It was only just eleven.

The second letter was longer and more troublesome to compose. It was to Grace Callender, and I trusted for its effect to the kindness she professed for me. Her aunt also had been friendly and had shown interest in the prospects of Carr Price's play. Neither, however, dreamed that success depended in any way upon Roger Odell.

"DEAR MISS GRACE," I wrote,--"You will think the request I'm going to make of you and Miss Callender a very strange one, but you promised that if you could help me you would do so. Well, extraordinary as it may seem, _you can make my fortune if you_ will both come to the Felborn Theatre at the unearthly hour of nine to-morrow morning, and ask to be shown into Mr. Felborn's private office. I shall be there, waiting and hoping to see you two ladies arrive promptly, as more than I can tell depends upon that. You happened to mention in my presence something about dining out to-night and returning rather late, so I feel there is a chance of your getting this and sending me a line by the messenger to the Belmont. He will wait for you, and I will wait for him.--Yours sincerely, JOHN HASLE."

An hour later the answer came to my hotel. "Of course we'll both be there on the stroke of nine. Depend upon us," Grace Callender replied.

"Thank Heaven!" I mumbled. Yet I was heavy with a sense of guilt. If it had been only for punishment, or only for my own advancement, I could not have done what I planned to do. No man could. But Grace Callender's happiness was at stake.

Roger Odell was five minutes before his time in Felborn's office next day, yet he found me on the spot. I saw by his face that his well-seasoned nerves were keyed not far from breaking-point. But he kept his role of the superior, indifferent man of the world. He hoped I didn't see the strain he was under, and I hoped that I hid my feelings from him. Each probably succeeded as well as the other.

"Well, what have you got to tell me?" he asked, when we were alone together in Julius Felborn's decorative private office.

"I've nothing to tell you," I said. "Nevertheless, I believe you will hear something if you've done as I suggested. Have you got the key or the combination of that big safe in the wall behind the desk?"

"I have the combination for to-day. Felborn was at the club last night when your letter came, and I asked him for it. There aren't many favours he wouldn't grant me. But what has Julius Felborn's safe to do with the case?"

"Please open it. We haven't much time to spare." I looked at my watch. In a quarter of an hour the Misses Callender ought to be announced. If they failed me after all--but I would not think of that "if."

Odell manipulated the combination, and the door of the safe swung open. I saw that there was room for a man inside, and explained to Odell that he must be the man. "It's absolutely necessary for you to hear for yourself," I insisted, "all that's said in this room during the next half-hour. If you didn't hear with your own ears, you'd never believe, and nothing would be said if you were known to be listening."

"You want me to eavesdrop!" he exclaimed, ready to be scornful.

"Yes," I admitted. "If you can call it eavesdropping to learn how and by whom Perry and Ned Callender Graham were done to death."

Without another word Odell stepped into the safe.

"With the door ajar you can hear every word spoken in this room," I said. "In a few minutes you'll recognise two voices--those of Miss Grace and Miss Marian Callender. I tell you this that you mayn't be surprised into making an indiscreet appearance. Remember your future's at stake and that of the girl you love. All you have to do is to keep still until the moment when the mystery is cleared up."

"How can it be cleared up by either of those two?" Odell challenged me, anger smouldering in his eyes.

"It will be cleared up while they are in the room," I amended. "Further than that I can't satisfy you now. By Jove! there goes the 'phone! I expect it's to say they're here, though it's five minutes before the time."

My guess was correct, and my answer through the telephone, "Let them come up at once," passed on the news to the man behind the door of the safe. I went out to the head of the stairs to meet my visitors, and led them into Felborn's office. The two were charmingly though very simply dressed, far more _les grandes dames_ in appearance than they had been on shipboard, and their first words were of amused admiration for the Oriental richness of Julius Felborn's office. It was evident that, whatever their secret preoccupations were, both wished to seem interested in their bizarre surroundings and in my success which they had come to promote. I made them sit down in the two most luxurious chairs the room possessed. Thus seated, their backs were toward the safe, and the light filtered becomingly through thin gold silk curtains on to their faces. I placed myself opposite, on an oak bench under the window. If the door of the safe moved, I could see it over the fashionable small hats of the ladies with their haloes of delicate, spiky plumes.

When I got past generalities I blurted out, "I've a confession to make. I won't excuse myself or explain, because when I've finished--though not _till_ then--you'll understand. On shipboard I talked of my book, and told you it was called _The Key_, but I didn't tell you that the title and one incident in the story were suggested--forgive my startling you--by the murder of Perry and Ned Callender-Graham."

"Oh!" exclaimed Grace, half rising, "you asked us here to tell us _that_? It doesn't seem _like_ you, Lord John."

"Give me the benefit of the doubt and hear me to the end," I pleaded, grieved by her stricken pallor and look of reproach as she sank into the chair again. Marian was pale also, even paler than usual, but her look was of anger, therefore easier to meet.

"You must not use the word 'murder,'" she commented, a quiver in her voice. "Your doing so shows that you've very little knowledge of the case."

"I beg your pardon," I said. "On the contrary, it precisely shows that I have knowledge of it. The brothers were murdered by the same hand, in the same way, and for the same motive."

Marian rose up, very straight and tall. "It would be more suitable to give your theories to the police than to us. I cannot stay and let my niece stay to listen to them."

"I shall have to give not my theories, but my knowledge, my proof, to the police," I warned her; "only it's better for everyone concerned for you to hear me first."

"You've brought us to this place under false pretences!" Marian cried, throwing her arm around the girl's waist. "It's not the act of a gentleman. Come, Grace, we'll go at once."

"For your own sakes you must not go," I insisted. "If you stay and hear me through some way may be found to save the family name from public dishonour."

"Dearest, we _must_ stay," Grace said steadily, when the older woman urged her toward the door.

Marian looked at her niece with the compelling look of a Fate, but the girl stood firm. Gently she freed herself from the clinging arm and sat, or rather fell, into the big cushioned chair once more. Her aunt hesitated for a moment, I could see, whether or not to use force, but decided against the attempt. With a level gaze of scorn for me, she took her stand beside Grace's chair, her hand clenched on the carving of its high back. I realised the tension of her grip, because her grey suede glove split open across a curious ring she always wore on the third finger of her left hand, showing its great cabochon emerald. I had often noticed this stone, and thought it like the eye of a snake.

"Say what you wish to say quickly, then, and get it over," she sharply ordered.

"The double murder was suggested and carried out by a man, but he had accomplices, and his principal accomplice was a woman." (Miss Callender's command excused my brusqueness.) "They had the same interest to serve; purely a financial interest. It was vital to both that Miss Grace Callender shouldn't marry--unless she married a person under their influence who would share with them. They preferred some such scheme, but it fell through. That drove them to extremes. Now I'll tell you something about this couple--this congenial husband and wife. Afterwards I'll give you details of their plot. They were married secretly years ago, and lived together when they could, abroad and on this side. The man was rich once, but lost his money--and the capacity to make it--by losing his health. Life wasn't worth living to either unless they could have the luxury they'd been used to. They took an old house on Long Island--Bay View Farm, near Sandy Plain. The man lived there for several months each year under the name of Paulling. His wife paid him flying visits. She provided the money, and had a banking account in the town. At Bay View Farm, when Miss Grace first engaged herself to her cousin, the two thought out their plot to suppress Perry. It took them some time to elaborate it, but a week before the wedding they were ready. The woman, still under the name of Paulling, engaged a furnished flat in New York, near Riverside Drive. She took this flat for a term of years, realising it might be needed more than once as time went on. In this apartment, in a house called the Alhambra, she sat down one day at her desk and wrote an anonymous letter to Perry Callender-Graham. She asked him to call at that address at midnight the next night and learn a secret concerning his cousin Grace's birth, which would change everything for them both if it came out. Her handwriting was disguised by the use of a quill pen, which used so much ink that most of the words left traces on the blotter. The envelope and paper were blue-grey, and thick. Inside was enclosed a small latchkey and a key to the front door of the house, for the hall-porter would be in bed by the time she named. Perry Callender-Graham could not resist the temptation to keep the appointment. He went to the Alhambra, let himself in, was seen by nobody, walked up to the third floor, and fitted the latchkey into the door on the right side of the hall. As he tried to turn the key something sharp as a needle pricked his forefinger. He was startled, yet he went on trying to unlock the door. The key turned all the way round, but the door stuck. It seemed to be bolted on the inside. He began to feel slightly faint, but he was so angry at being cheated that he pushed the electric bell, determined to get in at any cost. No answer came, however, and at last he gave up in despair. Some vague idea of warning the police and of going to see a doctor came to his mind, but he was already a dying man. Before he got as far as the street corner he fell dead. Exactly the same thing happened in the case of Ned, when every effort to frighten him into breaking his engagement had failed, when his love for his brother, his sensitive conscience and his superstitious fear had all been played upon in vain. Even the same formula was used for the anonymous letter, with a slightly different wording. That was safe enough, for if Perry had mentioned the first letter to Ned he would have told the police at the time of Perry's death; it would have been a valuable clue. It wasn't necessary to make new keys, for the two originals had been returned--'to the family.' They were sent anonymously to Ned as they'd been sent to Perry, and he also yielded to curiosity.
