"It must and shall be mine!"

So spoke Captain Ducie on the spur of the moment as he wrote the last word of his translation of M. Platzoff's MS. And yet there was a keen sense of disappointment working within him. His blood had been at fever heat during the latter part of his task. Each fresh sentence of the cryptogram as he began to decipher it would, he hoped, before he reached the end of it, reveal to him the hiding-place of the great Diamond. Up to the very last sentence he had thus fondly deluded himself, only to find that the abrupt ending of the MS. left him still on the brink of the secret, and left him there without any clue by which he could advance a single step beyond that point. He was terribly disappointed, and the longer he brooded over the case the more entirely hopeless was the aspect it put on.

But there was an elasticity of mind about Captain Ducie that would not allow him to despair utterly for any length of time. In the course of a few days, as he began to recover from his first chagrin, he at the same time began to turn the affair of the Diamond over and over in his mind, now in one way, now in another, looking at it in this light and in that; trying to find the first faint indications of a clue which, judiciously followed up, might conduct him step by step to the heart of the mystery. Two questions naturally offered themselves for solution. First: Did Platzoff habitually carry the Diamond about his person? Second: Was it kept in some skilfully-devised hiding-place about the house? These were questions that could be answered only by time and observation.

So Captain Ducie went about Bon Repos like a man with half-a-dozen pairs of eyes, seeing, and not only seeing but noting, a hundred little things such as would never have been observed by him under ordinary circumstances. But when, at the end of a week, he came to sum up and classify his observations, and to consider what bearing they had upon the great mystery of the hiding-place of the Diamond, he found that they had no bearing upon it whatever; that for anything seen or heard by him the world might hold no such precious gem, and the Russian's letter to Signor Lampini might be nothing more than an elaborate hoax.

When the access of chagrin caused by the recognition of this fact had in some degree subsided, Ducie was ready enough to ridicule his own foolish expectations. "Platzoff has had the Diamond in his possession for years. For him there is nothing of novelty in such a fact. Yet here have I been foolish enough to expect that in the course of one short week I should discover by some sign or token the spot where it is hidden, and that too after I knew from his own confession that the secret was one which he guarded most jealously. I might be here for five years and be not one whit wiser at the end of that time as regards the hiding-place of the Diamond than I am now. From this day I give up the affair as a bad job."

Nevertheless, he did not quite do that. He kept up his habit of seeing and noting little things, but without any definite views as to any ulterior benefit that might accrue to him therefrom. Perhaps there was some vague idea floating in his mind that Fortune, who had served him so many kind turns in years gone by, might befriend him once again in this matter—might point out to him the wished-for clue, and indicate by what means he could secure the Diamond for his own.

The magnitude of the temptation dazzled him. Captain Ducie would not have picked your pocket, or have stolen your watch, or your horse, or the title-deeds of your property. He had never put another man's name to a bill instead of his own. You might have made him trustee for your widow or children, and have felt sure that their interests would have been scrupulously respected at his hands. Yet with all this—strange contradiction as it may seem—if he could have laid surreptitious fingers on M. Platzoff's Diamond, that gentleman would certainly never have seen his cherished gem again. But had Platzoff placed it in his hands and said, "Take this to London for me and deposit it at my bankers'," the commission would have been faithfully fulfilled. It seemed as if the element of mystery, of deliberate concealment, made all the difference in Captain Ducie's unspoken estimate of the case. Besides, would there not be something princely in such a theft? You cannot put a man who steals a diamond worth a hundred and fifty thousand pounds in the category of common thieves. Such an act verges on the sublime.

One of the things seen and noticed by Captain Ducie was the absence, through illness, of the mulatto, Cleon, from his duties, and the substitution in his place of a man whom Ducie had never seen before. This stranger was both clever and obliging, and Platzoff himself confessed that the fellow made such a good substitute that he missed Cleon less than he at first feared he should have done. He was indeed very assiduous, and found time to do many odd jobs for Captain Ducie, who contracted quite a liking for him.

Between Ducie and Cleon there existed one of those blind unreasoning hatreds which spring up full-armed and murderous at first sight. Such enmities are not the less deadly because they sometimes find no relief in words. Cleon treated Ducie with as much outward respect and courtesy as he did any other of his master's guests; no private communication ever passed between the two, and yet each understood the other's feelings towards him, and both of them were wise enough to keep as far apart as possible. Neither of them dreamed at that time of the strange fruit which their mutual enmity was to bear in time to come. Meanwhile, Cleon lay sick in his own room, and Captain Ducie was rather gladdened thereby.

M. Platzoff rarely touched cigar or pipe till after dinner; but, whatever company he might have, when that meal was over, it was his invariable custom to retire for an hour or two to the room consecrated to the uses of the Great Herb, and his guests seldom or never declined to accompany him. To Captain Ducie, as an inveterate smoker, these sÉances were very pleasant.

On the very first evening of the Captain's arrival at Bon Repos, M. Platzoff had intimated that he was an opium smoker, and that at no very distant date he would enlighten Ducie as to the practice in question. About a week later, as they sat down to their pipes and coffee, said Platzoff, "This is one of my big smoke-nights. To-night I go on a journey of discovery into Dreamland—a country that no explorations can exhaust, where beggars are the equals of kings, and where the Fates that control our actions are touched with a fine eccentricity that in a more commonplace world would be termed madness. But there nothing is commonplace."

"You are going to smoke opium?" said Ducie, interrogatively.

"I am going to smoke drashkil. Let me, for this once, persuade you to follow my example."

"For this once I would rather be excused," said Ducie, laughingly.

Platzoff shrugged his shoulders. "I offer to open for you the golden gates of a land full of more strange and wondrous things than were ever dreamed of by any early voyager as being in that new world on whose discovery he was bent; I offer to open up for you a set of experiences so utterly fresh and startling that your matter-of-fact English intellect cannot even conceive of such things. I offer you all this, and you laugh me down with an air of superiority, as though I were about to present you with something which, however precious it might be in my eyes, in yours was utterly without value."

"If I sin at all," said Ducie, "it is through ignorance. The subject is one respecting which I know next to nothing. But I must confess that about experiences such as you speak of there is an intangibility—a want of substance—that to me would make them seem singularly valueless."

"And is not the thing we call life one tissue of intangibilities?" asked the Russian. "You can touch neither the beginning nor the end of it. Do not its most cherished pleasures fly you even as you are in the very act of trying to grasp them? Do you know for certain that you—you yourself—are really here?—that you do not merely dream that you are here? What do you know?"

"Your theories are too far-fetched for me," said Ducie. "A dream can be nothing more than itself—nothing can give it backbone or substance. To me such things are of no more value than the shadow I cast behind me when I walk in the sun."

"And yet without substance there could be no shadow," snarled the Russian.

"Do your experiences in any way resemble those recorded by De Quincey?"

"They do and do not," answered Platzoff. "I can often trace, or fancy that I can, a slight connecting likeness, arising probably from the fact that in the case of both of us a similar, or nearly similar, agent was employed for a similar purpose. But, as a rule, the intellectual difference between any two men is sufficient to render their experiences in this respect utterly dissimilar."

"It does not follow, I presume, that all the visions induced by the imbibing of opium, or what you term drashkil, are pleasant ones?"

"By no means. You cannot have forgotten what De Quincey has to say on that score. But whether they are pleasant or the contrary, I accept them as so much experience, and in so far I am satisfied. You look incredulous, but I tell you, sir, that what I see, and what I undergo—subjectively—while under the influence of drashkil make up for me an experience as real, that dwells as vividly in my memory and that can be brought to mind like any other set of recollections, as if it were built up brick by brick, fact by fact, out of the incidents of everyday life. And all such experiences are valuable in this wise: that whatever I see while under the influence of drashkil I see, as it were, with the eyes of genius. I breathe a keener atmosphere; I have finer intuitions; the brain is no longer clogged with that part of me which is mortal; in whatever imaginary scenes I assist, whether actor or spectator, matters not; I seem to discern the underlying meaning of things—I hear the low faint beating of the hidden pulses of the world. To come back from this enchanted realm to the dull realities of everyday life is like depriving some hero of fairyland of his magic gifts and reducing him to the level of common humanity."

"At which pleasant level I pray ever to be kept," said Ducie; "I have no desire to soar into those regions of romance where you seem so thoroughly at home."

"So be it," said Platzoff drily. "The intellects of you English have been nourished on beef and beer for so many generations that there is no such thing as spiritual insight left among you. We must not expect too much." This was said not ill-naturedly, but in that quiet jeering tone which was almost habitual with Platzoff.

Ducie maintained a judicious silence and went on puffing gravely at his meerschaum. Platzoff touched the gong and Cleon entered, for this conversation took place before the illness of the latter. The Russian held up two fingers, and Cleon bowed. Then Cleon opened a mahogany box in one corner of the room, and took out of it a pipe-bowl of red clay, into which he fitted a flexible tube five or six yards in length and tipped with amber. The bowl was then fixed into a stand of black oak about a foot high and there held securely, and the mouthpiece handed to Platzoff. Cleon next opened an inlaid box, and by means of a tiny silver spatula he cut out a small block of some black, greasy-looking mixture, which he proceeded to fit into the bowl of the pipe. On the top of this he sprinkled a little aromatic Turkish tobacco, and then applied an allumette. When he saw that the pipe was fairly alight, he bowed and withdrew.

While these preparations were going on Platzoff had not been silent. "I have spoken to you of what I am about to smoke, both as opium and drashkil," he said. "It is not by any means pure opium. With that great drug are mixed two or three others that modify and influence the chief ingredient materially. I had the secret of the preparation from a Hindoo gentleman while I was in India. It was imparted to me as an immense favour, it being a secret even there. The enthusiastic terms in which he spoke of it have been fully justified by the result, as you would discover for yourself if you could only be persuaded to try it. You shake your head. Eh bien! mon ami; the loss is yours, not mine."

"Some of what you have termed your 'experiences' are no doubt very singular ones?" said Ducie, interrogatively.

"They are—very singular," answered Platzoff. "In my last drashkil-dream, for instance, I believed myself to be an Indian fakir, and I seemed to realise to the full the strange life of one of those strange beings. I was stationed in the shade of a large tree just without the gate of some great city where all who came and went could see me. On the ground, a little way in front of me, was a wooden bowl for the reception of the offerings of the charitable. I had kept both my hands close shut for so many years that the nails had grown into the flesh, and the muscles had hardened so that I could no longer open them; and I was looked upon as a very holy man. The words of the passers-by were sweet in my ears, but I never spoke to them in return. Silent and immovable, I stood there through the livelong day—and in my vision it was always day. I had the power of looking back, and I knew that, in the first instance, I had been led by religious enthusiasm to adopt that mode of life. I should be in the world but not of it; I should have more time for that introspective contemplation the aim and end of which is mental absorption in the divine Brahma; besides which, people would praise me, and all the world would know that I was a holy man. But the strangest part of the affair remains to be told. In the eyes of the people I had grown in sanctity from year to year; but in my own heart I knew that instead of approaching nearer to Brahma, I was becoming more depraved, more wicked, with a great inward wickedness, as time went on. I struggled desperately against the slough of sin that was slowly creeping over me, but in vain. It seemed to me as if the choice were given me either to renounce my life of outward-seeming sanctity, and becoming as other men were, to feel again that inward peace which had been mine long years before; or else, while remaining holy in the eyes of the multitude, to feel myself sinking into a bottomless pit of wickedness from which I could never more hope to emerge. My mental tortures while this struggle was going on I can never forget: they are as much a real experience to me as if they had made up a part of my genuine waking life. And still I stood with closed hands in the shade of the tree; and the people cried out that I was holy, and placed their offerings in my bowl; and I could not make up my mind to abnegate the title they gave me and become as they were. And still I grew in inward wickedness, till I loathed myself as if I were some vile reptile; and so the struggle went on, and was still going on when I opened my eyes and found myself again at Bon Repos."

As Platzoff ceased speaking, Cleon applied the light, and Ducie in his eagerness drew a little nearer. Platzoff was dressed À la Turk, and sat with cross legs on the low divan that ran round the room. Slowly and deliberately he inhaled the smoke from his pipe, expelling it a moment later, in part through his nostrils and in part through his lips. The layer of tobacco at the top of the bowl was quickly burnt to ashes. By this time the drug below was fairly alight, and before long a thick white sickly smoke began to ascend in rings and graceful spires towards the roof of the room. Cleon was gone, and a solemn silence was maintained by both the men. Platzoff's eyes, black and piercing, were fixed on vacancy; they seemed to be gazing on some picture visible to himself alone. Ducie was careful not to disturb him. His inhalations were slow, gentle and regular. After a time, a thin film or glaze began to gather over his wide-open eyes, dimming their brightness, and making them seem like the eyes of someone dead. His complexion became livid, his face more cadaverous than it naturally was. Then his eyes closed slowly and gently, like those of an infant dropping to sleep. For a little time longer he kept on inhaling the smoke, but every minute the inhalations became fainter and fewer in number. At length the hand that held the pipe dropped nervelessly by his side, the amber mouthpiece slipped from between his lips, his jaw dropped, and, with an almost imperceptible sigh, his head sank softly back on to the cushions behind, and M. Paul Platzoff was in the opium-eater's paradise.

Ducie, who had never seen anyone similarly affected, was frightened by his host's death-like appearance. He was doubtful whether Platzoff had not been seized with a fit. In order to satisfy himself he touched the gong and summoned Cleon. That incomparable domestic glided in, noiseless as a shadow.

"Does your master always look as he does now after he has been smoking opium?" asked the Captain.

"Always, sir."

"And how long does it take him to come round?"

"That depends, sir, on the strength of the dose he has been smoking. The preparation is made of different strengths to suit him at different times; but always when he has been smoking drashkil I leave him undisturbed till midnight. If by that time he has not come round naturally and of his own accord, I carry him to bed and then administer to him a certain draught, which has the effect of sending him into a natural and healthy sleep, from which he awakes next morning thoroughly refreshed."

"Then you will come to-night at twelve, and see how your master is by that time?" said Ducie.

"It is part of my duty to do so," answered Cleon.

"Then I will wait here till that time," said the Captain. Cleon bowed and disappeared.

So Ducie kept watch and ward for four hours, during the whole of which time Platzoff lay, except for his breathing, like one dead. As the last stroke of midnight struck Cleon reappeared. His master showed not the slightest symptom of returning consciousness. Having examined him narrowly for a moment or two, he turned to Ducie.

"You must pardon me, sir, for leaving you alone," he said, "but I must now take my master off to bed. He will scarcely wake up for conversation to-night."

"Proceed as though I were not here," said Ducie. "I will just finish this weed, and then I too will turn in."

Platzoff's private rooms, forming a suite four in number, were on the ground floor of Bon Repos. From the main corridor the first that you entered was the smoking-room already described. Next to that was the dressing-room, from which you passed into the bed-room. The last of the four was a small square room, fitted up with book-shelves, and used as a private library and study.

Cleon, who was a strong, muscular fellow, lifted Platzoff's shrivelled body as easily as he might have done that of a child, and so carried him out of the room.

Ducie met his host at the breakfast-table next morning. The latter seemed as well as usual, and was much amused when Ducie told him of his alarm, and how he had summoned Cleon under the impression that Platzoff had been taken dangerously ill.

Platzoff rarely indulged in the luxury of drashkil-smoking oftener than once a week. His constitution was delicate, and a too frequent use of so dangerous a drug would have tended to shatter still further his already enfeebled health. Besides, as he said, he wished to keep it as a luxury, and not, by a too frequent indulgence in it, to take off the fine edge of enjoyment and render it commonplace. Ducie had several subsequent opportunities of witnessing the process of drashkil-smoking and its effects, but one description will serve for all. On every occasion the same formula was gone through, precisely as first seen by Ducie. The pipe was charged and lighted by Cleon (after he became ill, by the new servant Jasmin). Precisely at midnight Cleon returned, and either conducted or carried his master to bed, as the necessities of the case might require. It was his knowledge of the latter fact that stood Ducie in such good stead later on, when he came to elaborate the details of his scheme for stealing the Great Hara Diamond.

But as yet his scheme was in embryo. His visit was drawing to a close, and he was still without the slightest clue to the hiding-place of the Diamond.
