Chapter IX: Part 9

"Action for damages and that kind of thing, I suppose," Tanza chuckled. "Forcible abduction of an honest British citizen. Heavy damages, presumably. Oh, I have no doubt we shall have trouble of that kind, but if you leave Bark to me I think I can find a way to reduce him to reason. Give me a few hints when we get back, for when I talk to Bark I wish to let him know that I am well posted in what has taken place. Practically, I could write a history of the whole transaction, though I am in the dark as to the way in which this business has been engineered."

"Electrically engineered, I suppose?" Grey asked.

"That's it," Tanza said eagerly. "That is the point on which I am somewhat dubious. If you enlighten me I can tackle Bark efficiently. It had best come through me."

"It shall," Grey said curtly. "Here is the boat and we have Swift to deal with."

In the inner office Swift was still walking round the charred remains of the fire, muttering to himself and quite oblivious that he was no longer alone. He stared vacantly at his companions. It seemed impossible to beat anything like sense into his head. He was palpably on the verge of a breakdown. What he needed was a powerful drug and sleep, which, evidently, he had been without for some time. Tanza shook his head gravely as he watched the unhappy man.

"A bad case," he muttered. "Look at the pupils of his eyes. If that man doesn't sleep before long he will be a raving maniac. But it is not too late to save him if he is properly looked after. I don't envy his feelings when he comes to himself. What a pity it was you didn't warn me about this, so that I could have brought my drugs with me."

"I am sorry," Grey murmured. "But what are we going to do? There is little to be gained by hanging about like this."

There was nothing for it but strong measures. And, despite his struggles and protestations, Swift was carried to the boat, shouting and singing as he went. Fortunately, it was a quiet spot, and there was not much chance of attracting the attention of the passers-by. But Grey drew a deep breath of relief when the boat touched the yacht side and Swift was hauled unceremoniously aboard. A few minutes later Tanza got to work with his drugs and hypodermic syringe, and gradually Swift's cries and protestations died away. The dilation of his pupils narrowed and lessened. The wild look on his face gave place to a more placid expression, then by degrees his breathing grew more regular, his head fell forward on his breast, and he slept. Tanza watched him with satisfaction.

"That's all right," he said. "Now let us get the poor fellow to bed. He is not likely to wake for eight or ten hours, and when he does so I don't envy his feelings. I daresay I can keep him in hand with a judicious application of drugs. But the pity of it, my dear fellow, the pity of it! Fancy talent like that being frittered away in this foolish fashion. Upon my word, I had a great mind to devote the best part of six months to Swift's mental regeneration. I think it would be worth the trouble, and he could repay me by initiating me into those scientific mysteries so essential to the pursuit of my hobby."

"I wish you would," Grey murmured. "I am sure that Swift would do you credit. It isn't as if the poor chap had a natural weakness for drink; but he has no friends and he has drifted into this terrible habit. It is a good thing you have a crew you can rely upon. Otherwise we should have been hard put to it to carry this daring scheme into execution. Now let us get this fellow to bed and send for Bark."

Swift was put to bed at once and Bark fetched. A grinning sailor came up in response to Tanza's summons with the information that Bark was in a state of furious indignation and demanded to be released without delay.

"He seems to be annoyed, then?" Tanza asked pleasantly.

"Carrying on something awful, sir," the grinning sailor responded. "But, seeing as the orders were yours, we just let him talk and took no notice. Do you want him here, sir? Certainly, sir."

The sailor vanished, and a moment later a pair of unseen hands pushed Bark violently into the cabin. He came in staggering and rolling, making, however, some attempt at dignity, which was lost upon his captors. Tanza closed the door and turned the key in the lock. Then he wheeled round and faced the infuriated Bark, who stammered and stuttered with rage.

"What is the meaning of this?" he demanded. "Why this outrage? Why couldn't you have sent for me as a gentleman would have done? Am I a free British subject, or am I not?"

Tanza smiled.

"I will answer your questions one at a time," he said coolly. "You ask me why this outrage. Now, I put it to you as a far-seeing man with more than the ordinary share of brains--would you have preferred us to bring you on board the yacht, or would you rather have had the thing done through the medium of a policeman?"

"You are talking rubbish," Bark blustered.

"My good Bark, I am not in the habit of talking rubbish, as you very well know. It suits Mr. Grey and myself to work this matter out in our own way, without fuss or bother. Besides, we wanted to remove you beyond reach of temptation. So long as you were free to go your own way there was always the danger of Mrs. Charlock's jewels falling into your hands. And we objected to that. You will stay here just as long as we like, and, if I am anything of a prophet, you will be thanking us before long for the interest we have taken in your welfare."

"I am a free British subject," Bark cried.

"No, I beg your pardon, you are nothing of the sort. You are a prisoner on board this yacht, and here you are likely to remain for the present. Besides, how long would you be free if you once got ashore? I have only to mention one or two matters which we know of to the police and your boasted freedom would come to a speedy end. You may as well take it quietly. You will gain nothing by bluster, and you can't frighten my crew. If I were to put you in irons and take you a voyage round the world, not one of my men would interfere. But you need not be alarmed. I have not the least desire for your company on a voyage of circumnavigation, and that, singularly enough, is why you are here to-night. I know the remark sounds illogical, but you will see how sensible it is before long."

"Go on," Bark said theatrically. "Keep it up. I see that you are enjoying yourself."

"I am," Tanza said crisply. "Nothing gives me such pleasure as the elucidation of a crime. It is a positive joy to me to bring a scoundrel to book. And yet I am really the best friend you have, because I am saving you later from being charged with the murder of Mrs. John Charlock!"

*CHAPTER XLIV*

*BROUGHT TO BOOK*

Bark quailed visibly before the eyes of his companion. He ceased to stand upright. His back was bowed and bent, his head was buried in his shoulders. His jaunty air vanished. The cynical smile faded from his lips. The pallor of his face and a shadow of fear in his eyes told their story.

"I swear I don't know what you mean," he said hoarsely. "For God's sake, don't talk like that, doctor. Oh, I am a bad lot, and I own it. Call me a scamp if you like, and I'll not deny it. You know all about me, doctor. But I am not as bad as all that. It had never occurred to me--no, not for all the money in the world--to do violence to a fellow-creature. I am innocent of bloodshed, if this is the last word that I am ever allowed to speak."

"Ah, now you are coming to your senses," Tanza said. "It is one thing to feel sure of a man's innocence, but it is another thing to prove it. Now, let us regard this matter from the point of view of the Crown Prosecutor who is opening the case against you. You have a sister who was Mrs. John Charlock's maid. This sister was carrying on an intrigue with a celebrated chemist whom we will call--but why make a parable of it? Let us call him by his proper name of Arnold Rent. This Rent was simply making a tool of your sister, because he wished to get her mistress's jewels. He is a far-seeing young man and, to use a common expression, has a pretty good notion of his own interest. Like many a clever young man before him, he has gone a bit too far. He is up to his eyes in debt and difficulty and dare not tell his mother, who is a bit of a fanatic in her way and quite capable of leaving her money elsewhere if she thinks her son is likely to make a bad use of it. Therefore he conceives the idea of getting hold of Mrs. Charlock's jewels. We won't go into the love affair, because that does not concern either of us, though it has a bearing on the story. Your sister Hortense acts as this man's tool and robs her mistress of her diamonds. For the present the stones are hidden in a secure place, which is known only to the thief and to Arnold Rent. It is just at this time that the thief discovers that she is merely a pawn in the game; it is her mistress who is the object of Rent's affections. The girl is beside herself with jealousy, though Rent manages to soothe her to a certain extent. For her own protection, however, she writes a letter to her brother, telling him how he can find the jewels in case anything happens to her. She is not too explicit as to the hiding-place, and this brother has to exercise his ingenuity as to the way in which the stones may be brought to light. At this point a tragedy occurs, and the girl is found dead in the fountain by the sundial in her employer's garden. Appearances point to suicide or accident. Nobody guesses that the poor woman is the victim of foul play, and I don't suppose they ever would if, perchance, I had not come here in my yacht for a little change and the thing happened to come to my ears. Rightly or wrongly, I concluded there was something wrong and sent for my friend Mr. Grey. To make a long story short, we discovered that I was absolutely right, and in a few hours we shall be able to prove that your sister was deliberately murdered. Whether Mrs. Charlock met with the same fate or not, we are not able at present to say. And now, Bark, are you going to deny your conviction, or stick to the fable that your sister's death was an accident? Didn't you come here with the intention of seeking out the hiding-place of those jewels? Take time to reply. You will gain nothing by lying. We happen to know where the jewels are, and we can put our hands upon them at any moment. We are not in the least afraid of being anticipated by you, because, even if we gave you a plan of the hiding-place, you couldn't touch them. If you attempted to do so, a third victim would be added to those who have already lost their lives in connexion with those ill-fated gems. You can please yourself whether you speak or not; if you like, I will unlock the door and send you ashore at once."

But Bark did not appear anxious to accept this offer. He sat writhing uneasily in his chair, his face turned eagerly to Tanza, as if waiting for the latter to continue. But the Italian said no more. He had given Bark his lesson and waited patiently for its effect.

"You are too many for me," Bark said presently. "You know too much. I might just as well tell the truth. My sister did write to me and tell me all about Arnold Rent, and I came here hot-foot to help her in the matter of those jewels. It was a shock to me to hear of her death, but I didn't suspect anything at the time. She was always a hot-headed, impulsive girl, and I naturally thought she had committed suicide. But when I came to inquire into the matter I formed another conclusion altogether. I asked myself a question or two, but I couldn't answer them. It occurred to me that perhaps Arnold Rent could. I had known him for some years. He is all right as men go, but put him in a tight place and he would stick at nothing. I thought the matter out, and at last I began to see my way. Hortense had been murdered. There was no doubt about that. But how had it been done? There were no marks of violence. There was nothing to show that she had met with a violent end, except that she was lying in the fountain. I couldn't get rid of the notion that Rent was in some way connected with this business, and I was confirmed in my opinion by his keeping out of my way. It is a pity he isn't able to tell us the truth. He knows all about it."

"You should have thought about that before you assaulted him," Grey put in quietly. "Don't forget that you are responsible for Rent's present mental condition."

A queer sort of laugh broke from Bark's lips.

"Oh, so you know about that, too?" he exclaimed. "It does not appear to be much good trying to keep anything from you gentlemen. Mind you, I didn't mean to do him any harm, but he refused to pay me money he owed me, and I lost my temper. If I had waited a bit longer I could have told him a thing or two which would have compelled him to listen to me. I could have forced him to give me all the money I needed. But there it is, and the thing can't be helped. And I don't think I could tell you any more if you kept me talking till daybreak. I'll help you all I can. I'll do anything you want me to do. I think I have sense enough to know when I am in a tight corner."

Tanza rose and unlocked the door.

"That is all at present. I should like to see the letter your sister wrote you--I mean the letter about the hidden jewels, which gave you the clue to the hiding-place. We can put you up for the night on the yacht, if you like; indeed, you will be well advised to stay here. I don't think, after what has happened, you are likely to play us false. You have had too severe a lesson."

Bark asserted, with many oaths, that he had no intention of doing anything of the kind. He evinced a not unnatural anxiety to be alone. He was thoroughly cowed and as wax in the hands of his captors. Grey gave a sigh of relief as Bark vanished from the cabin.

"His room is preferable to his company," he said. "What a pestiferous little rascal it is! I don't think he is likely to give us any trouble in the future. And how well you handled him. Your cross-examination was masterly."

Tanza shrugged his shoulders modestly.

"Could I have failed," he asked, "with all the cards in my hand? Why, the fellow hadn't the ghost of a chance. But he has been useful to us, and the only thing that remains to be done is to get this matter over as soon as possible. I am correct in assuming, I suppose, that Mrs. Charlock met the same fate as her maid?"

"You mean that she was murdered?" Grey asked.

"Well, I didn't want to put it so brutally."

"I think you are wrong," Grey went on. "Mind, I am only theorising. I believe that Hortense was murdered in cold blood. But as regards Mrs. Charlock, I treat that more or less as an accident. The man who laid the trap forgot to take the bait out of it, and thus unwittingly brought about the second catastrophe. But that we shall be able to clear up later. It is a ghastly business altogether, and, for my part, I am sorry I was ever brought into it. Not that I have the least sympathy with the guilty parties. But I am grieved for the innocent people who are bound to suffer. It will be hard upon Mrs. Rent."

Tanza nodded gravely. He was about to reply, when he was interrupted by the sound of footsteps on deck overhead and the entrance of a sailor with the information that Mr. John Charlock had just come on board and desired to see Mr. Grey on important business. At the same moment Charlock thrust a haggard face into the cabin and the seaman vanished.

"What is it?" Tanza demanded.

"A terrible thing has happened," Charlock said hoarsely. "Arnold Rent has thrown himself out of his bedroom window. He is not dead, but I am told he cannot last many hours. And, strange to say, he has been asking for you, Mr. Grey."

*CHAPTER XLV*

*THE HIDING-PLACE*

"How did you come to know?" Grey demanded.

"Miss Hargrave told me. I suppose she couldn't think of anybody else, and she could not bear to break the news herself to Mrs. Rent. It was just before daylight."

"Daylight!" Tanza echoed. "Daylight, when?"

"Why, this morning," Charlock went on. "Don't you know that it is morning? I suppose you have been sitting here with the blinds drawn over the portholes, oblivious of the flight of time. At any rate, it is nearly five o'clock. But please allow me to go on with my story. As far as I could gather from Miss Hargrave, she went into Rent's room yesterday afternoon and found him fast asleep. He had apparently been reading a bundle of letters, for they had fallen from his knee and lay in a mass on the carpet. Quite mechanically the poor girl picked the letters up, and a word in one of them caught her eye and she began to read. She was so shocked and upset by what she saw that she came to me at once and told me about it. But you shall read for yourself, for the letters are in my possession."

"I don't think you need worry about that," Grey said. "Unless I am greatly mistaken, I know pretty well what those letters contain. They had been written by Rent to the French maid, Hortense; in fact, they are the very letters which Rent obtained from your house on the night that Miss Hargrave came inquiring for Rent. But, of course, I have forgotten that you know nothing about that, because you left me to see Miss Hargrave home. But don't let me interrupt you. I only want you to know that we are not quite so ignorant as you think us. I suppose I am right as to the gist of those letters?"

"Absolutely," Charlock went on. "You can imagine Miss Hargrave's state of mind. I was touched to see how she confided in me and promised to do all I could to help her. There were passages in those letters which throw a lurid light upon many things that have happened lately, and that was why I implored Miss Hargrave to do nothing rash. You see, I wanted to save Mrs. Rent and herself from as much trouble and scandal as possible. I implored the girl to go back home and say nothing whatever about her discovery. She promised that she would do so, and when she had regained control of herself I allowed her to go. But I might have known that one so ingenuous and innocent would find it impossible to carry about so dreadful a secret. For some time she managed to master herself, but an hour or so ago Rent had a lucid interval and guessed something was wrong. Perhaps his seared conscience pricked him. Perhaps he surmised that the trouble had something to do with himself, for he insisted upon the girl telling him everything. She did so, with the result that you already know. So far as I could gather, when Miss Hargrave came to me just now in a state of mind bordering on distraction, Rent affected to take the matter quite calmly. He rose from his seat and talked on indifferent topics for several minutes. Then he lighted a cigarette and stood by the open window of his bedroom admiring the beauty of the morning. A minute or two later he flung himself over the balcony on to the stones below, and was picked up by a labourer in a dying condition. They carried him into his room and sent for the doctor. I am told the poor fellow suffers only occasionally, but they say that he cannot recover from the shock and that death is not far off. He has fits of insensibility, followed by periods of lucidity, during which time his mind is clear. Strange to say, the blank in his memory has been filled up, and, from what he told Miss Hargrave, he knows everything that has taken place during the past fortnight. As yet, his mother has not been told; indeed, she was asleep when I came from the house."

There was a long pause when Charlock had finished. Tanza and Grey regarded one another significantly.

"It is a shocking thing," the latter said presently. "But it has all happened for the best. Of course, I will see Rent if he wants me. I shall be here all day and you have only to send a messenger over."

"That is very good of you," Charlock murmured. "If you don't mind, I will go back at once. There are many ways in which I can be useful. Directly Rent gains consciousness again I will not fail to send."

Charlock went on his way back to the darkened household. It was not too late to snatch an hour or two in bed, and, despite the startling events of the evening before, Grey slept soundly directly he reached his cabin. When he woke the sun was shining brightly and Tanza was standing by his side. Grey sat up in bed and rubbed his eyes.

"Anything fresh?" he asked. "I suppose you have had no messages yet from Charlock?"

"Not a word," Tanza said. "I have allowed Bark to go away under a promise that he will remain at hand and come here whenever he is wanted. I have not the least fear that he will play us false after what has happened. Meanwhile, for the last hour or so I have been bestowing my attention upon Swift."

"I hope he is better," Grey murmured.

"Well, he is clear and sensible, if that is what you mean. He is in a terribly shaken state and hasn't the smallest idea what took place last night. I have been reminding him about one or two things and you will find him ready to answer questions. I have given him a soothing draught, and I don't think he is likely to trouble us for some time, at any rate. After breakfast you can interview him."

Grey found Swift a white and pitiable object, propped up by pillows, doing his best to coax down a little food. There was a half-pleading, half-defiant look in his eyes as Grey seated himself on the bed.

"You needn't be afraid of me," Grey said. "I only want you to give me a little information. My dear fellow, if you only knew it, Tanza and myself are the best friends you have. Tanza has announced his intention of devoting himself to your case, and if you only play the man, he will set you on your feet again. I cannot understand how one of your ability should sink so low. Surely, if we hold out a helping hand----"

"That is all I want," Swift interposed eagerly. "I am a double-dyed fool, Grey, and no one knows it better than myself. When I started to go down hill my friends began to turn their backs upon me, and I went on drinking out of sheer bravado. For the last two years I have been alone in the world; but, low as I have fallen, I would make a big effort to pull myself together if I could find a congenial friend. If Tanza would take me in his employ it would be a godsend to me. I could make a struggle under a man like that. But, there, you did not come here to talk about myself. What have you discovered? And what can I do for you?"

"Practically, we have discovered everything," Grey said gravely. "We have made certain of what we have hitherto regarded only as suspicion. You are weak and ill, and I don't want to bother you unnecessarily. Tell me in a word, has Arnold Rent discovered intermittent electricity or not?"

Swift nodded his head vigorously.

"That will do," Grey went on. "You need not say any more. There will be plenty of time to go in for explanations when you are well enough. All I want to know now is the exact position of the underground dynamo which was established some time ago within a few hundred yards of Rent's offices. I don't suppose he told you about it, but I am sure you know where the thing is to be found."

By way of reply, Swift reached for his coat, which was lying across the back of his bunk, and took from the breast-pocket a sheet of tracing-paper, which he handed over to Grey. The latter glanced at it and smiled. When he turned to Swift again the patient was lying with closed eyes as if on the verge of sleep. Grey stole from the cabin to the deck where Tanza was seated.

"Come along," he said. "I have it at my fingers' ends. I'll just get a pair of india-rubber gloves and shoes and a mat and we can set out at once."

They came at length to a spot some little way from the workshop, where Grey proceeded to make a close examination of the turf. He lifted a sheet of sod presently and disclosed a small grating underneath. Kneeling on the india-rubber mat and carefully shielding his hands with gloves of the same material, he proceeded to pull out a switch or two and cut through a cable which led into the tiny manhole. Then, without a further word to Tanza, he strode right on until he came to the lawn of Charlock's house, pausing at length in front of the fountain which surrounded the sundial. With the gloves still upon his hands, and the long rubber boots upon his feet, he waded through the water until he stood by the side of the sundial. He raised the cap and threw it aside. Then from the cavity below he produced a small box.

"There!" he said, with an air of subdued triumph. "Will you please examine the contents? I will forfeit my reputation if Mrs. Charlock's jewels are not inside."

*CHAPTER XLVI*

*THE PRICE OF A CRIME*

Tanza unfastened the box and removed a sheet of cotton wool which lay on the top. The sun gleamed on a heap of stones of various sizes, diamonds for the most part, which streamed and twinkled as if they had been running water. Then he laid out the rings and necklaces and the various odds and ends, which went to make up a collection of stones worth a considerable amount. The Italian knew something about jewels, and in his estimation at least ten thousand pounds' worth of jewels lay on their bed of cotton wool.

"Mrs. Charlock appeared to have a pretty taste in this respect," Tanza remarked. "These things might have belonged to the wife of a millionaire. So this is the end of our search. Well, those stones have done mischief, goodness knows. I suppose you can tell me how they managed to get there?"

"All in good time," Grey replied. "We had better return to the yacht and talk the matter over. Besides, Rent may send for me at any moment, and I should not like to be out of the way when his message comes. It has been an exciting venture on the whole, and, to a certain extent, I have enjoyed it. But I would give half of what I possess not to have to face Mrs. Rent, as I shall be compelled to do presently."

Tanza nodded sympathetically. He understood what Grey was alluding to. The latter replaced the capstone on the sundial and proceeded to strip off his rubber boots and gloves. Tanza touched these articles lightly with his finger-tips.

"Did you really need these?" he asked. "Was there actual danger? I saw you were taking no risks."

"It was a necessary precaution," Grey explained. "Of course, you know that in handling high-volted coils and cables there is always danger. Anything beyond five hundred volts needs great caution. You are well aware, also, that a voltage which is almost harmless when one is dry or standing on dry ground becomes dangerous in the presence of moisture. The perfect safeguard is in using india-rubber gloves and boots. With these one can handle cables carrying practically any power."

Tanza nodded his approval.

"I know all that," he said. "But what first put the idea of electricity into your head? As you know, from the very first I suspected foul play. I felt certain the Frenchwoman met her death by some new and ingenious method of manslaughter. In thinking the matter over, electricity suggested itself to my mind, but I could not for the life of me see how it was worked. That is why I called you in. You seem to have known from the start what to do and what to look for. Isn't that a fact?"

"Well, I had luck on my side," Grey admitted. "You remember bringing me to have a look round the place and giving me a minute account of the way in which Hortense met her death. You will recollect telling me that her dress was more or less singed, which seemed remarkable, seeing that she had apparently met her death by water. There were no marks of violence on the body, either, which was another thing that aroused one's suspicions. I was still asking myself a few questions in this direction when I had the good luck to pick up a thumb torn from an india-rubber glove. Now, you know india-rubber gloves are worn almost entirely by electrical engineers; indeed, I know no other use for them. I am aware that burglars have adopted the same precaution to prevent any identification of finger-marks. But, then, your average burglar does not give as much as two guineas a pair for india-rubber gloves, which is somewhere about the price of those from which the thumb was torn. As soon as that evidence came into my hands I knew that somebody connected with electricity had been near the sundial. But the mere presence of a fountain disposed of the suggestion that anything like the usual electrical business had been contemplated by the owner of the property. I dropped a hint to Charlock, and he knew nothing about it. Now, why had this mysterious individual been here? And what was he doing in the neighbourhood of the fountain? A little farther up the lawn I discovered a small piece of cable properly insulated, and then I became more or less certain of my facts. Somebody had laid a wire from the sundial to a power station in the neighbourhood. It puzzled me why this had been done till I began to put things together, and I suddenly recollected what you told me about Hortense's clothing being scorched. It seemed fair to assume that the sundial and the fountain were charged for some reason with a dangerous load of electricity, and that directly the woman came into contact with the water she was killed instantly. Doubtless she fell forward into the fountain, which would account for the scar upon her forehead. You see, the current might have been powerful enough to cause instant death without unduly injuring the body. Before I left these premises that day I knew beyond the shadow of a doubt how the French maid had met her death. You follow me?"

"Absolutely," Tanza said. "It is quite logical."

"Of course it is," Grey went on. "There is no other way of accounting for it. Then I began to ask myself what the woman was doing near the fountain. Until I could get to the bottom of that I was more or less groping in the dark. But, then, as you know now, I had an opportunity of examining Hortense's bedroom, where, in the fireplace, I found a torn photograph of two men, one of whom was Rent. Who the other man is probably we shall never know, and, in any case, it doesn't matter. At any rate, we have the fact that Hortense was in the possession of Rent's photograph, which she had torn across the middle, no doubt in a moment of petulance and passion. I may be wrong, but that is the interpretation I put upon it. It was more or less natural to conclude that tender passages had passed between Hortense and himself. I could not guess why for the moment, but it became clear later. But this is not all the evidence I discovered. In the grate were fragments of a letter which pointed to the fact that some secret was on foot connected with the sundial. It was not till after I heard that Mrs. Charlock had lost her jewels that I began to wonder if the gems had been hidden in the sundial. I had to speculate upon this for a day or two, until I caught Bark loafing about the lawn, and then I felt sure my supposition was correct. When I saw that Bark had severely burnt his fingers in the waters of the fountain I became certain of my ground. It was lucky for him that the night was fine and the grass dry, or he would have shared the fate of his sister. By this time my suspicions were growing pretty strong. I could not come to any other conclusion but that Rent was at the bottom of the whole business. Where else could the power station which supplied the electricity be except in Rent's own workshop? And who besides himself was interested in getting Hortense out of the way? Beyond a doubt she had found out how she had been fooled and had threatened revenge. Therefore he determined to get rid of her by this diabolically ingenious means, which it would be impossible to trace. He had only to let the girl know where the jewels were hidden, and she was certain to try to steal them. To a man who has discovered the secret of intermittent electricity the thing was easy. You know in how small a compass an electrical plant goes and how easy it is to manipulate. Suppose a hole is cut in the ground by the fountain and a wire inserted into the water. Then, a quarter of a mile away, another apparatus is hidden underground, the current turned on from the works, and without intermediate wires a contact is made between one pole and another. Of course, I know it sounds very extraordinary, but if you can telegraph and telephone without wires, why shouldn't you transmit an ordinary electrical current? At any rate, Rent succeeded in doing so, as Swift more or less intimated to me; in fact, he found out what was going on and gave me a plan of the direction in which the apparatus ran. I shouldn't be surprised if Swift knows as much as we do, and no doubt his guilty knowledge has driven him to drink. I have proved how this thing was done and how the French girl was sent to her death."

"You think she was murdered?" Tanza asked.

"Most emphatically I do. Otherwise, why should Rent go to the trouble of all these elaborate preparations? He was afraid that Hortense would betray him to her mistress. He was so infatuated with Mrs. Charlock that he was prepared to run any risk to retain her good opinion. I feel convinced that Hortense was sent deliberately to her death, and if you and I had not happened to be in the neighbourhood the thing would have been forgotten and nobody been any the wiser. Why, apart from such proofs as I have given you just now, there are other people who could support my assertions. Don't you suppose that that blackguard Bark knows all about it? And he was prepared to keep his mouth shut and leave his sister's death unpunished if only he could get possession of the jewels. It is a ghastly business altogether. And now you understand why I am not anxious to face Mrs. Rent. And you will see that the matter cannot be allowed to rest here. What a sensation there will be when it all comes out!"

*CHAPTER XLVII*

*ABSOLUTION*

Tanza shook his head slowly and sorrowfully. "Terrible!" he murmured. "I wish we could find some way of keeping Mrs. Rent and Miss Hargrave out of this matter. But after what has taken place the thing is impossible. Mrs. Rent will have to give evidence, and so will Miss Hargrave. One is naturally loth to interfere with the course of justice. But if ever there was a case where a policy of silence would be pardonable, this assuredly is that case. Only in one contingency the world need know nothing of this miserable affair."

"And what may that be?" Grey asked.

"Why, the death of Arnold Rent, of course. If he would considerately die, we should be perfectly justified in keeping our own counsel. Why should the thing be dragged to light? Why should the whole painful story be made public when the culprit is beyond the reach of the law? I think you will agree with me."

"Oh, I do," Grey confessed. "But please don't imagine that Arnold is worse than he appears to be. You don't suppose that he is responsible for the death of Mrs. Charlock as well? That would be too dreadful."

"Is there any other conclusion?" Tanza asked.

"Well, yes, in common justice to Rent, there is. I believe that Mrs. Charlock's death was a sheer accident. Let me retrace the ground, and I will show you what I mean. We will admit, if you like, that Rent is a man without heart and without principle. We will make one exception, and that was his pure and disinterested affection for Mrs. Charlock. He was prepared to sacrifice his future for her sake. Oh, yes, I know that he stole her diamonds. But no doubt that was in the early stage of his infatuation. Afterwards he must be credited with good intentions. You see, he had removed the French maid, and the ground appeared to be clear. So deeply in love is he that he takes Mrs. Charlock to stay with his mother. Mind you, in taking that step he knew what he was risking. He knew how strict and rigid his mother was, and how little versed she was in the ways of the world. These upright and honourable people are apt to be narrow-minded. And religion and charity are not always the same thing. I say that when Rent took Mrs. Charlock into Devonshire he was running the risk of losing every penny of his expectations. Of course, there was the hope of conciliating his mother, but that was what one might call a sporting chance. As you know, the scheme was a failure, and Mrs. Charlock went away, posing as a martyr, prepared to accept any sacrifice rather than injure the prospects of the man who had befriended her. Anyway, there was an end of her so far as the home in Devonshire was concerned. Now, if my theory is correct, there was a subsequent interview between Mrs. Charlock and Rent, in which the situation was reviewed from a worldly point of view. You see, they were bound to face the situation sooner or later; in sporting parlance, the thing wasn't good enough for Mrs. Charlock, and she probably let Rent know it in her sweet, unsophisticated way. No doubt he had time to think the matter over and began to grasp what he was sacrificing. Whether they parted in friendly fashion or not doesn't matter. They _did_ part, and Mrs. Charlock came back to her husband. Before she started, Rent doubtless did the fair thing and told her where her jewels were hidden. But there was one thing he forgot--he neglected to turn off those switches, and left the fountain in the same dangerous condition as when Hortense met with her dreadful death. Either that or Swift had been experimenting with the apparatus. But the fact remains that the charge had not been drawn from the mine, and when Mrs. Charlock went to regain possession of her jewels she went to certain death. That is my rendering of the matter, though I may be wrong."

"I should think it exceedingly probable you are right," Tanza said. "You have given me a sensible and logical account of what has happened, and I fail to see any flaw in your argument. We had better return to the yacht now, and later I will hand these stones to Charlock. There ought to be enough here to free him from all his difficulties and enable him to come back to his own house. Unless I am mistaken, he will be glad to resume possession once more."

"Why should he be?" Grey asked.

"Because he is in love with Ethel Hargrave," Tanza said. "One can see that with half an eye. And what is more, the girl is in love with him. But these things are in the air at present. So far as I am concerned, I should be disposed to keep our discovery a profound secret. That rascal Bark will not dare to say anything, and I flatter myself I can find a way to keep Swift's mouth closed. Unfortunately, Miss Hargrave has made some discoveries, but we may be able to convince her that she has made a mistake. If Arnold Rent dies, which seems more than probable, we may save the scandal altogether. Charlock we can trust."

They were back at the yacht again presently, still discussing the tragedy in which they were both profoundly interested. There was no sign of Bark, and Swift seemed to be decidedly better. After luncheon Tanza had a long talk with him, and left him in appreciably higher spirits. Just as the Italian arrived on deck again an urgent message came for Grey, saying that Mr. Rent desired to see him immediately.

Grey found Rent sitting in bed, propped up with pillows. It needed no practised eye to see that the end was near. Mrs. Rent and Ethel were with the sufferer, and at a sign from him they left him and Grey together. Rent was very weak and low, yet there was a resolute look in his eyes, and he lost no time in coming directly to the point.

"You know why I sent for you?" he demanded.

"I can give a fair guess," Grey murmured.

"Ah, I am glad of that, because it will save me a deal of talking, and time is precious. Tell me in a few words what you have discovered. It would be a kindness to speak frankly and openly to me."

"Perhaps it would," Grey said. "Then I may say I have discovered everything. Nothing is hidden from me."

"This is what I expected," the dying man murmured. "I have felt that ever since you have been in the neighbourhood. Oh, I know what Tanza was after. I have not been altogether blind. But I swear to you that so far as Mrs. Charlock was concerned I am absolutely and entirely innocent. It was a cruel misfortune--but go on, please. Let me hear your story first."

"There is not much to tell," Grey said, picking up the thread. "To begin with, I know all about your entanglement with the French maid. An accident put me on the track, but it is a waste of time to go into that. I know what happened between your workshop and the fountain. I know how you laid the trap which led Hortense to her death. But perhaps I had better tell it to you just as I told it to Tanza a little while ago."

Grey proceeded over the familiar ground, the dying man following with rapt attention. At the end of the recital he nodded more or less approvingly.

"So far," he said, "you have not made a mistake. You have the thing as clear and plain as if you had been in my place. But you are wrong as far as Mrs. Charlock was concerned. I had disconnected the electrical apparatus which communicated with the fountain; indeed, I was going to destroy everything but for an accident which prevented me. I call it an accident for want of a better term. But now I see the hand of Fate in it. I was playing with the apparatus one night when Hortense's brother, Bark, came into my office. He asked me for money, which I was not able to give him, and one word leading to another, the whole thing culminated in a serious quarrel. I was knocked down and sustained an injury to my head which, as you know, affected my brain. In most ways I was sane enough, but memory of the events of the past few days had been wholly blotted out. I was haunted by the feeling that I had left something undone, but I could not for the life of me recall what it was. You can imagine a murderer who has gone off and left a clue behind. That was the sensation that maddened me and spoilt all my rest till Ethel Hargrave found me poring over certain letters. It was only when she began to speak that remembrance came back to me swiftly and unexpectedly. Ethel knew too much. I knew that I could not hope to silence her tongue. Besides, she had already confessed all she had discovered to John Charlock. Then it was that a feeling of abject despair came over me, and in the madness of the moment I threw myself out of the window. When sense and reason returned once more everything was wonderfully clear again. I recalled the whole train of circumstances. And the more I pondered it the more hopeless my position seemed. I tell you, I was glad to know that I must die, that I was going to leave all this shame and misery behind me. And it is simply because I am dying that I sent for you to-day. I want you, if you can, to prevent a scandal. I want these dreadful things kept from my mother."

*CHAPTER XLVIII*

*SEALED IN THE GRAVE*

"It can be done," Grey murmured.

The pupils of Rent's eyes dilated strangely.

"Man, it must be concealed," he said hoarsely. "Try to conceive the cruelty of making all these matters public when the one human being who ought to suffer is beyond the reach of justice! What you know and what Tanza knows I can regard as safe. I could die comfortably in the knowledge that you would never speak, and I am certain that John Charlock would remain silent for the sake of my mother and that innocent girl who has come to think so ill of me. Surely you need not undeceive her! Surely you can think of some plausible fiction! If ever there was a case where a lie is justified, this is the occasion. Now promise."

"I will do all I can," Grey said freely and heartily. "And I know that I can speak for Tanza, too; indeed, I may go further and say that he advocated the very course you are suggesting. He assumed that if the worst happened--I beg your pardon, I should not have put it as bluntly as that."

"But that is just the way I want you to put it," Rent insisted. "You don't know what a load you have taken off my mind. And now I will ask you to leave me. I should like to have my mother with me for the little time that remains----"

The speaker broke off suddenly. Something seemed to choke his utterance. He dropped back on his pillow, breathing faintly. His eyes closed. Very gently Grey crept from the room downstairs to where the others were waiting. The expression of his face was quite enough for Mrs. Rent, who hurried away, followed by Ethel. A little while later the girl came downstairs, her manner soft and subdued. Grey raised his eyebrows interrogatively.

"Yes," Ethel whispered. "He went off peacefully. The nurse and doctor were in the room at the time. I don't know whether you will mind my bringing up the subject just now, but Mr. Charlock has mentioned the matter to you. There were certain letters which my relative had in his possession----"

"I hope they are destroyed," Grey said. "I know what you are alluding to. But it would be as well if those letters were burnt, because it is probable they may lead you to a wrong conclusion. I know you have had a rough time lately, but that mustn't make you suspect crime. I think Mr. Charlock is of the same opinion as myself and deprecates your arriving at a hasty inference. Try to recollect that, however black a case may look against a person, the whole complexion of the thing may lie changed when his defence is disclosed."

A look of relief crossed the girl's face.

"I suppose that is so," she suggested timidly.

"Indeed it is," Grey said emphatically. "But, whatever you do, don't allude to anything in Mrs. Rent's presence. She has enough sorrow and misery to contend with as it is. Now, if you will excuse me, I had better go. This is no place for a stranger."

Grey was glad to find himself outside the house, glad to know that his unpleasant errand had ended without more disastrous consequences. He went at once in search of John Charlock, whom he found disconsolately wandering about his garden. He looked somewhat guilty as Grey came up.

"I don't know what you must think of me," he said, "but I find it difficult to tear myself away from this place. You see, all my hopes and ambitions were centered here. It was here that I looked forward to a happy life. I have just begun to see the fruition of my ambitions, to see my reputation established. I am a free man now and the grave contains my one mistake. I don't say that I feel any regret at what has taken place, beyond the horror that such tragedies bring. But I don't want to talk about myself. What can I do for you?"

"You can come aboard the yacht and talk matters over with Tanza," Grey suggested. "We have several things to discuss with you and one or two confessions to make. I may be a false prophet, but I am sure that the best part of your life's happiness is still to come. But let us eschew platitudes. Come with me and let us have the matter out."

Charlock expressed himself willing, and a little later the two men were on their way to the yacht. For the best part of an hour or more Charlock listened to all that Tanza and his companion had to say. Finally he took the case of jewels which the Italian handed to him and slipped it in his pocket.

"I am infinitely obliged to you gentlemen," he said. "As to these jewels, they rightly belong to me. They have been paid for, too, and their sale will enable me to take possession of my old house again. I daresay I shall be reasonably happy. No doubt I can find some worthy woman who will act as housekeeper and look after my servants. But I am afraid that my dream of a perfect home must remain a dream, for it is never likely to be realised. I am forced to the conclusion that I am not the sort of man to make a woman----"
