"Ah," she murmured reflectively, "he was the most fine stern man ... and he gave me hundred-franc notes."

Then she was gone. We never saw nor heard of Yvette again.

Out of curiosity, I turned to look at the picture which must have caught her eye. It was a little photograph, framed in black, and hung by itself on the wall; in the ordinary way one would scarcely have noticed it. I went close up to it. My heart gave a jump, and I seemed to perspire. The photograph was a portrait of the man who, since my acquaintance with Rosa, had haunted my footsteps—the mysterious and implacable person whom I had seen first opposite the Devonshire Mansion, then in the cathedral at Bruges during my vigil by the corpse of Alresca, then in the train which was wrecked, and finally in the Channel steamer which came near to sinking. Across the lower part of it ran the signature, in large, stiff characters, "Clarenceux."

So Lord Clarenceux was not dead, though everyone thought him so. Here was a mystery more disturbing than anything which had gone before.


CHAPTER XIV

THE VILLA

It seemed to be my duty to tell Rosa, of course with all possible circumspection, that, despite a general impression to the contrary, Lord Clarenceux was still alive. His lordship's reasons for effacing himself, and so completely deceiving his friends and the world, I naturally could not divine; but I knew that such things had happened before, and also I gathered that he was a man who would hesitate at no caprice, however extravagant, once it had suggested itself to him as expedient for the satisfaction of his singular nature.

A light broke in upon me: Alresca must have been aware that Lord Clarenceux was alive. That must have been part of Alresca's secret, but only part. I felt somehow that I was on the verge of some tragical discovery which might vitally affect not only my own existence, but that of others.
