Platzoff passed quickly from stage to stage of the process, till, in no long time, complete coma supervened, and he lived no longer save in the opium-smoker's fantastic world. The light in his pipe died out, the amber mouthpiece slipped from between his lips, his fingers relaxed their hold on the stem, his head drooped, his jaw fell slightly, a thin dark line marked the space between his imperfectly closed eyelids. He sighed gently twice, and was gone.
To all these signs Captain Ducie was now well accustomed, and he regarded them entirely as a matter of course. He refilled his pipe, and lay back, with his hands clasped under his head, gazing up at the gaudy ceiling, and building pleasant castles in the air. As the clock struck twelve, Cleon or Jasmin would enter, and he himself would go to roost for a couple of hours. Then would come the time for his great enterprise.
He had been thus quietly engaged with his second pipe, for a space of five or six minutes, when, finding that it did not draw to his mind, he sat up with the view of ascertaining what was the matter with it. In the act of opening his knife, he turned his eyes unthinkingly on M. Platzoff. In the face of the silent man sitting opposite to him there was something that caused his own face to blanch in a moment, as though he had seen some unmentionable horror. He rose to his feet as though moved by some invisible agency. Great beads of sweat burst out on his brow; his lips turned blue; in his eyes was a terror unspeakable. He staggered forward with a groan, and lifted the cold hand that would never grasp his again.
"My God! I have killed him!"
He sank on his knees, and buried his face in his hands. He knew as well as if twenty doctors had told him so, that M. Paul Platzoff, of Bon Repos, was dead. On his forehead was stamped the Great Angel's ineffaceable seal. Death had whispered in his ears, and he was deaf for ever.
That one minute which Ducie spent on his knees was, perhaps, the bitterest of his life. What his feelings were he himself could not have told. "As heaven is my witness, I did not intend to do this thing!" he exclaimed aloud, as he rose to his feet.
Then, in spite of the certainty which possessed him that Platzoff was beyond all earthly aid, he bared one of the Russian's arms, and pricked a vein with his penknife. But no blood followed, and with another groan Ducie let go the fingers that were already growing cold and stiff.
His next impulse was to ring for assistance. But in the very act of pulling the bell-rope he paused. For a minute or two the very existence of such a bauble as the Great Mogul Diamond had passed entirely out of his thoughts. But as his fingers touched the rope, there came a whisper in his ear, "Now or never the Diamond must become yours!" He paused, and sat down for a moment to think.
Platzoff was gone past recovery. Of all men living he, Ducie, was probably the only one to whom the existence of the Diamond was known; or, at least, the place where it was hidden. Dead men tell no tales. If he were to make the Diamond his,--and had he not a right to do so, having paid such a tremendous price for it--who in all the wide world would be one bit the wiser? If, on the contrary, he were to leave it untouched, it might remain undiscovered in its dark home for centuries, perhaps even till the end of time. Or if Platzoff's friend, Signor Lampini, were sufficiently instructed where to find it, of what use would it be to him except as a means for the propagation of red-hot revolutionary ideas, among which, for aught he knew to the contrary, assassination might be looked upon as a cardinal virtue? He would be worse than a fool not to seize the last chance that would ever be offered him of making the precious gem his own for ever.
Once more he looked at his watch. It wanted exactly a quarter to twelve. He had fifteen clear minutes that he could call his own, and not one minute more. No suspicion would attach to him with regard to the death of Platzoff; he felt no uneasiness on that score. But after that event should be discovered, the pass-key would be claimed by Cleon, and all access to the rooms denied him. Now or never was his time.
