you would do all that. Later, as the sedative action began to gain on the stimulant action, you would slowly become inert and stupefied. Later still you would fall into a deep sleep. When the morning came, and the effect of the opium had been all slept off, you would wake as absolutely ignorant of what you had done in the night as if you had been living at the Antipodes.—Have I made it tolerably clear to you so far?"
"You have made it so clear," I said, "that I want you to go farther. You have shown me how I entered the room, and how I came to take the Diamond. But Miss Verinder saw me leave the room again, with the jewel in my hand. Can you trace my proceedings from that moment? Can you guess what I did next?"
"That is the very point I was coming to," he rejoined. "It is a question with me whether the experiment which I propose as a means of vindicating your innocence, may not also be made a means of recovering the lost Diamond as well. When you left Miss Verinder's sitting-room, with the jewel in your hand, you went back in all probability to your own room—"
"Yes? and what then?"
"It is possible, Mr. Blake—I dare not say more—that your idea of preserving the Diamond led, by a natural sequence, to the idea of hiding the Diamond, and that the place in which you hid it was somewhere in your bedroom. In that event, the case of the Irish porter may be your case. You may remember, under the influence of the second dose of opium, the place in which you hid the Diamond under the influence of the first."
It was my turn, now, to enlighten Ezra Jennings. I stopped him, before he could say any more.
"You are speculating," I said, "on a result which cannot possibly take place. The Diamond is, at this moment, in London."
He started, and looked at me in great surprise.
"In London?" he repeated. "How did it get to London from Lady Verinder's house?"
"Nobody knows."
"You removed it with your own hand from Miss Verinder's room. How was it taken out of your keeping?"
"I have no idea how it was taken out of my keeping."
"Did you see it, when you woke in the morning?"
"No."
"Has Miss Verinder recovered possession of it?"
"No."
