"Well, yes, I was," I admitted.

He looked at me curiously for a moment.

"I see you don't know me very well, even yet, Lester," he said, at last. "I'm sorry you didn't let me see it. It would have saved me a wild-goose chase. But then," he added, with a grim little laugh, "I might not have stumbled upon this second tragedy. So perhaps it was as well, after all. I forgive you."

"You think the photograph would have made the mystery clearer?" I asked.

"Clearer?" he echoed. "My dear Lester, it makes it more unexplainable than ever. It converts it from a vulgar intrigue into the most puzzling problem I ever had to deal with!"

I was staring at him in astonishment.

"I don't see how it can do that!" I protested.

"Don't you? Well, I'll tell you. I've already pointed out to you that, so far as I could see, my theory was the only conceivable one which would explain Marcia Lawrence's flight. I look at that photograph and see at once that I must throw that theory aside. What have I left? Nothing! That photograph shows me a pure, cultured, innocent woman; I know that she loved devotedly the man she was to marry. Yet she deliberately deserts him. I should say it was incredible, if I didn't know it was true!"

"Then," I said, "while we've solved one mystery, the other is as deep as ever."

"Deeper!" he corrected. "Miles deeper. In fact, it hasn't any bottom at all, that I can see," and he sank back into his seat again, a deep line between his eyebrows.
