He walked back a few steps towards the middle of the room, and stood still again.
Thus far, he had exactly repeated what he had done on the birthday night. Would his next proceeding be the same as the proceeding of last year? Would he leave the room? Would he go back now, as I believed he had gone back then, to his bed-chamber? Would he show us what he had done with the Diamond, when he had returned to his own room?
His first action, when he moved once more, proved to be an action which he had not performed, when he was under the influence of the opium for the first time. He put the candle down on a table, and wandered on a little towards the farther end of the room. There was a sofa there. He leaned heavily on the back of it, with his left hand—then roused himself, and returned to the middle of the room. I could now see his eyes. They were getting dull and heavy; the glitter in them was fast dying out.
The suspense of the moment proved too much for Miss Verinder's self-control. She advanced a few steps—then stopped again. Mr. Bruff and Betteredge looked across the open doorway at me for the first time. The prevision of a coming disappointment was impressing itself on their minds as well as on mine.
Still, so long as he stood where he was, there was hope. We waited, in unutterable expectation, to see what would happen next.
The next event was decisive. He let the mock Diamond drop out of his hand.
It fell on the floor, before the doorway—plainly visible to him, and to everyone. He made no effort to pick it up: he looked down at it vacantly, and, as he looked, his head sank on his breast. He staggered—roused himself for an instant—walked back unsteadily to the sofa—and sat down on it. He made a last effort; he tried to rise, and sank back. His head fell on the sofa cushions. It was then twenty-five minutes past one o'clock. Before I had put my watch back in my pocket, he was asleep.
It was all over now. The sedative influence had got him; the experiment was at an end.
I entered the room, telling Mr. Bruff and Betteredge that they might follow me. There was no fear of disturbing him. We were free to move and speak.
'The first thing to settle,' I said, 'is the question of what we are to do with him. He will probably sleep for the next six or seven hours, at least. It is some distance to carry him back to his own room. When I was younger, I could have done it alone. But my health and strength are not what they were—I am afraid I must ask you to help me.'
Before they could answer, Miss Verinder called to me softly. She met me at the door of her room, with a light shawl, and with the counterpane from her own bed.
'Do you mean to watch him while he sleeps?' she asked.
'Yes, I am not sure enough of the action of the opium in his case to be willing to leave him alone.'
She handed me the shawl and the counterpane.
'Why should you disturb him?' she whispered. 'Make his bed on the sofa. I can shut my door, and keep in my room.'
It was infinitely the simplest and the safest way of disposing of him for the night. I mentioned the suggestion to Mr. Bruff and Betteredge—who both approved of my adopting it. In five minutes I had laid him comfortably on the sofa, and had covered him lightly with the counterpane and the shawl. Miss Verinder wished us good night, and closed the door. At my request, we three then drew round the table in the middle of the room, on which the candle was still burning, and on which writing materials were placed.
'Before we separate,' I began, 'I have a word to say about the experiment which has been tried to-night. Two distinct objects were to be gained by it. The first of these objects was to prove, that Mr. Blake entered this room, and took the Diamond, last year, acting unconsciously and irresponsibly, under the influence of opium. After what you have both seen, are you both satisfied, so far?'
They answered me in the affirmative, without a moment's hesitation.
'The second object,' I went on, 'was to discover what he did with the Diamond, after he was seen by Miss Verinder to leave her sitting-room with the jewel in his hand, on the birthday night. The gaining of this object depended, of course, on his still continuing exactly to repeat his proceedings of last year. He has failed to do that; and the purpose of the experiment is defeated accordingly. I can't assert that I am not disappointed at the result—but I can honestly say that I am not surprised by it. I told Mr. Blake from the first, that our complete success in this matter depended on our
