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 completely reproducing in him the physical and moral conditions of last year--and I warned him that this was the next thing to a downright impossibility. We have only partially reproduced the conditions, and the experiment has been only partially successful in consequence. It is also possible that I may have administered too large a dose of laudanum. But I myself look upon the first reason that I have given, as the true reason why we have to lament a failure, as well as to rejoice over a success."
After saying those words, I put the writing materials before Mr. Bruff, and asked him if he had any objection—before we separated for the night—to draw out, and sign, a plain statement of what he had seen. He at once took the pen, and produced the statement with the fluent readiness of a practiced hand.
"I owe you this," he said, signing the paper, "as some atonement for what passed between us earlier in the evening. I beg your pardon, Mr. Jennings, for having doubted you. You have done Franklin Blake an inestimable service. In our legal phrase, you have proved your case."
Betteredge's apology was characteristic of the man.
"Mr. Jennings," he said, "when you read Robinson Crusoe again (which I strongly recommend you to do), you will find that he never scruples to acknowledge it, when he turns out to have been in the wrong. Please to consider me, sir, as doing what Robinson Crusoe did, on the present occasion." With those words he signed the paper in his turn.
Mr. Bruff took me aside, as we rose from the table.
"One word about the Diamond," he said. "Your theory is that Franklin Blake hid the Moonstone in his room. My theory is, that the Moonstone is in the possession of Mr.
