night Ducie's mind was too excited to allow of sleep. He was about to be shown the great Diamond; but would the mere fact of seeing it advance him one step towards obtaining possession of it? Would Platzoff, when showing him the stone, show him also the place where it was ordinarily kept? His confidence in Ducie would scarcely carry him as far as that. In any case, it would be something to have seen the Diamond, and for the rest, Ducie must trust to the chapter of accidents and his own wits. On one point he was fully determined—to make the Diamond his own at any cost, if the slightest possible chance of doing so were afforded him. He was dazzled by the magnitude of the temptation; so much so, indeed, that he never seemed to realise in his own mind the foulness of the deed by which alone it could become his property. Had any man hinted that he was a thief, either in act or intention, he would have repudiated the term with scorn—would have repudiated it even in his own mind, for he made a point of hoodwinking and cozening himself, as though he were some other person whose good opinion must on no account be forfeited.
Captain Ducie awaited with hidden impatience the hour when it should please M. Platzoff to fulfil his promise. He had not long to wait. Three evenings later, as they sat in the smoking-room, said Platzoff: "To-night you shall see the Great Hara Diamond. No eyes save my own have seen it for ten years. I must ask you to put yourself for an hour or two under my instructions. Are you minded so to do?"
"I shall be most happy to carry out your wishes in every way," answered Ducie. "Consider me as your slave for the time being."
"Attend, then, if you please. This evening you will retire to your own rooms at eleven o'clock. Precisely at one-thirty a.m., you will come back here. You will be good enough to come in your slippers, because it is not desirable that any of the household should be disturbed by our proceedings. I have no further orders at present."
"Your lordship's wishes are my commands," answered Ducie, with a mock salaam.
They sat talking and smoking till eleven; then Ducie left his host as if for the night. He lay down for a couple of hours on the sofa in his dressing-room. Precisely at one-thirty he was on his way back to the smoke-room, his feet encased in a pair of Indian mocassins. A minute later he was joined by Platzoff in dressing-gown and slippers.
"I need hardly tell you, my dear Ducie," began the latter, "that with a piece of property in my possession no larger than a pigeon's egg, and worth so many thousands of pounds, a secure place in which to deposit that property (since I choose to have it always near me) is an object of paramount importance. That secure place of deposit I have at Bon Repos. This you may accept as one reason for my having lived in such an out-of-the-world spot for so many years. It is a place known to myself alone. After my death it will become known to one person only—to the person into whose possession the Diamond will pass when I shall be no longer among the living. The secret will be told him that he may have the means of finding the Diamond, but not even to him will it become known till after my decease. Under these circumstances, my dear Ducie, you will, I am sure, excuse me for keeping the hiding-place of the Diamond a secret still—a secret even from you. Say—will you not?"
With a malediction at his heart, but with a smile on his lips, Captain Ducie made reply. "Pray offer no excuses, my dear Platzoff, where none are needed. What I want is to see the Diamond itself, not to know where it is kept. Such a piece of information would be of no earthly use to me, and it would involve a responsibility which, under any circumstances, I should hardly care to assume."
"It is well; you are an English gentleman," said the Russian, with a ceremonious inclination of the head, "and your words are based on wisdom and truth. It is necessary that I should blindfold you: oblige me with your handkerchief."
Ducie with a smile handed over his handkerchief, and Platzoff proceeded to blindfold him—an operation which was rapidly and effectually performed by the deft fingers of the Russian.
"Now, give me your hand and come with me, but do not speak till you are spoken to."
So Ducie laid a finger in the Russian's thin, cold palm, and the latter, taking a small bronze hand-lamp, conducted his bandaged companion from the room.
In two minutes after leaving the smoke-room Ducie's geographical ideas of the place were completely at fault. Platzoff led him through so many corridors and passages, turning now to the right hand, and now to the left—he guided him up and down so many flights of stairs, now of stone and now of wood, that he lost his reckoning entirely and felt as though he were being conducted through some place far more spacious than Bon Repos. He counted the number of stairs in each flight that he went up or down. In two or three cases the numbers tallied, which induced him to think that Platzoff was conducting him twice over the same ground, in order perhaps the more effectually to confuse his ideas as to the position of the place to which he was being led.
After several minutes spent thus in silent perambulation of the old house, they halted for a moment while Platzoff unlocked a door, after which they passed forward into a room, in the middle of which Ducie was left standing while Platzoff relocked the door, and then busied himself for a minute in trimming the lamp he had brought with him, which had been his only guide through the dark and silent house, for the servants had all gone to bed more than an hour ago.
Ducie, thus left to himself for a little while, had time for reflection. The floor on which he was standing was covered with a thick, soft carpet, consequently he was in one of the best rooms in the house. The atmosphere of this room was penetrated with a very faint aroma of pot-pourri, so faint that unless Captain Ducie's nose had been more than ordinarily keen he would never have perceived it. To the best of his knowledge there was only one room in Bon Repos that was permeated with the peculiar scent of pot-pourri. That room was M. Platzoff's private study, to which access was obtained through his bed-room. Ducie had been only twice into this room, but he remembered two facts in connection with it. First, the scent already spoken of; secondly, that besides the door which opened into it from the bed-room, there was another door which he had noticed as being shut and locked both times that he was there. If the room in which they now were was really M. Platzoff's study, they had probably obtained access to it through the second door.
While silently revolving these thoughts in his mind, Captain Ducie's fingers were busy with the formation of two tiny paper pellets, each no bigger than a pea. Unseen by Platzoff, he contrived to drop these pellets on the carpet.
"I must really apologise," said the Russian, next moment, "for keeping you waiting so long; but this lamp will not burn properly."
"Don't hurry yourself on my account," said Ducie. "I am quite jolly. My eyes are ready bandaged; I am only waiting for the axe and the block."
"We are not going to dispose of you in quite so summary a fashion," said the Russian. "One minute more and your eyesight shall be restored to you."
Ducie's quick ears caught a low click, as though someone had touched a spring. Then there was a faint rumbling, as though something were being rolled back on hidden wheels.
"Lend me your hand again, and bend that tall figure of yours. Step carefully. There is another staircase to descend—the last and the steepest of all."
Keeping fast hold of Platzoff's hand, Ducie followed slowly and cautiously, counting the steps as he went down. They were of stone, and were twenty-two in number. At the bottom of the staircase another door was unlocked. The two passed through, and the door was shut and relocked behind them.
"Be blind no longer!" said Platzoff, taking off the handkerchief and handing it to Ducie, with a smile. A few seconds elapsed before the latter could discern anything clearly. Then he saw that he was in a small vaulted chamber about seven feet in height, with a flagged floor, but without furniture of any kind save a small table of black oak on which Platzoff's lamp was now burning. The atmosphere of this dungeon had struck him with a sudden chill as he went in. At each end
