It was plain that his conduct was looked upon as strange, and I felt some anxiety lest it should appear more so before the evening was over. I found him at last in his room, sitting with his head buried in his arms. He started up as I entered.
"Well?" he asked sharply.
"I have learned nothing decisive."
"Nor I."
"I exchanged some words with both ladies and I tackled Beaton; but the matter remains just about where it was. It may have been Dorothy who took the box and it may have been Gilbertine. But there seems to be greater reason for suspecting Dorothy. She lives a terrible life with that aunt."
"And Gilbertine is on the point of escaping that bondage. I know; I have thought of that. Walter, you are a generous fellow;" and for a moment Sinclair looked relieved. Before I could speak, however, he was sunk again in his old despondency. "But the doubt," he cried—"the doubt! How can I go through this rehearsal with such a doubt in my mind? I cannot and will not. Go, tell them I am ill, and cannot come down again to-night. God knows you will tell no untruth."
I saw that he was quite beside himself, but ventured upon one remonstrance.
"It will be unwise to rouse comment," I said. "If that box was taken for the death it holds, the one restraint most likely to act upon the young girl who retains it will be the conventionalities of her position and the requirements of the hour. Any break in the settled order of things—anything which would give her a moment by herself—might precipitate the dreadful event we fear. Remember, one turn of the hand, and all is lost. A drop is quickly swallowed."
"Frightful!" he murmured, the perspiration oozing from his forehead. "What a wedding-eve! And they are laughing down there. Listen to them. I even imagine I hear Gilbertine's voice. Is there unconsciousness in it, or just the hilarity of a distracted mind bent on self-destruction? I cannot tell; the sound conveys no meaning to me."
"She has a sweet, true face," I said, "and she wears a very beautiful smile to-night."
