They left me then without another word. I heard their footsteps die away along the corridor, the ring of the lift bell, the clatter of its ascent and descent. Then I undressed and went to bed.

I awoke the next morning rather late, dressed and shaved in my rooms, and descended to the café for breakfast. The waiter who usually served me came hurrying up with a welcoming smile.

"Monsieur Louis," he announced, "returned early this morning."

"He is not here now?" I asked, looking around the room.

The waiter smiled deprecatingly.

"But for the early breakfast, no, sir!" he said. "Monsieur Louis will come at one o'clock, perhaps,—perhaps not until dinner-time. He will be here to-day, though."

I unfolded my paper and looked through the list of accidents. There was nothing which could possibly have applied to Mr. Delora. I waited until eleven o'clock, and then sent up my name to Miss Delora. A reply came back almost at once,—Miss Delora had gone out an hour ago, and had left no word as to the time of her return. Once more I was puzzled. Why should she go out unless she had received some news? She had told me that she had no friends in London. It was scarcely likely that she would go out on any casual expedition in her present state of uncertainty. I made my way to the manager's office, whom I knew very well, and with whom I had often had a few minutes' talk. He received me with his usual courtesy, and gave me a handful of cigarettes to try. I lit one, and seated myself in his easy-chair.

"Mr. Helmsley," I said, "you know that I am not, as a rule, a curious person, and I should not like to ask you any questions which you thought improper ones, but you have some guests staying here in whom I am somewhat interested."

Mr. Helmsley nodded, and by his genial silence invited me to proceed.

"I mean Mr. Delora and his niece," I continued.
