The porter looked dubious for a moment.

"I don't absolutely remember, sir," he said, "but I know that it was one of the big railway stations."

The clerk turned to me.

"Is there anything else you would like to ask?" he inquired.

I shook my head.

"No, thanks!" I answered. "I am afraid there is nothing more to be learned."

The porter went back to his duties, and I bade the clerk good night. Up in my room Fritz was waiting anxiously.

"You were right and wrong," I announced. "Mr. Delora has been staying here and left to-night."

"He has gone!" Fritz exclaimed.

"He left at eleven o'clock," I answered. "He saw me, and I suppose he knew that I was looking for him. Here's half your money, anyhow," I continued, giving him a five-pound note. "The next thing to do is to find out where he has gone to. I think you could help here, Fritz."
