feel tempted to reply. Why should a servant deliver a warning against his own master? If you will be patient with me you will soon see; but first I wish to make it clear that Mrs. Fairbrother, having received this warning just before Mr. Durand appeared in the alcove,—reckless, scheming woman that she was!—sought to rid herself of the object against which it was directed in the way we have temporarily accepted as true. Relying on her arts, and possibly misconceiving the nature of Mr. Durand’s interest in her, she hands over the diamond hidden in her rolled-up gloves, which he, without suspicion, carries away with him, thus linking himself indissolubly to a great crime of which another was the perpetrator. That other, or so I believe from my very heart of hearts, was the man I saw leaning against the wall at the foot of the alcove a few minutes before I passed into the supper-room.” I stopped with a gasp, hardly able to meet the stern and forbidding look with which the inspector sought to restrain what he evidently considered the senseless ravings of a child. But I had come there to speak, and I hastily proceeded before the rebuke thus expressed could formulate itself into words. “I have some excuse for a declaration so monstrous. Perhaps I am the only person who can satisfy you in regard to a certain fact about which you have expressed some curiosity. Inspector, have you ever solved the mystery of the two broken coffee-cups found amongst the debris at Mrs. Fairbrother’s feet? It did not come out in the inquest, I noticed.” “Not yet,” he cried, “but—you can not tell me anything about them!” “Possibly not. But I can tell you this: When I reached the supper-room door that evening I looked back and, providentially or otherwise—only the future can determine that—detected Mr. Grey in the act of lifting two cups from a tray left by some waiter on a table standing just outside the reception-room door. I did not see where he carried them; I only saw his face turned toward the alcove; and as there was no other lady there, or anywhere near there, I have dared to think—” Here the inspector found speech. “You saw Mr. Grey lift two cups and turn toward the alcove at a moment we all know to have been critical? You should have told me this before. He may be a possible witness.” I scarcely listened. I was too full of my own argument.
