e man answered. "He went at about eleven o'clock."

"Did he go in a cab?" the clerk asked.

"In a four-wheeler, sir," the porter answered.

"Do you remember what address he gave?"

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."

"What must I do?" the man asked.

"First of all," I said, "go to the big railway hotels and try and find
out from one of the porters--you Germans all stick together--whether
any one arrived in a four-wheel cab at between eleven and twelve this
evening, whose description coincides with that of Mr. Delora. I reckon
that will take you most of to-morrow. When you have finished come to
me at the Milan Court, and let me know how you have got on."

"So!" the man remarked, rising from his seat. "To-morrow morning I will
do that. They will tell me, these fellows. I know many of them."

"Good night, Fritz, then!" I said. "Good luck!"

CHAPTER XXVII

WAR

Early on the following morning I moved back to my rooms in the Milan
Court. Curiously enough I entered the building with a sense of
depression for which I could not account. I went first to my own rooms
and glanced at my letters. There was nothing there of importance. In
other words, there was nothing from Felicia. I descended to the fifth
floor and knocked at the door of her room. As I stood there waiting I
was absolutely certain that somehow or other a change had occurred in
the situation, that the freeness of my intercourse with Felicia was
about to be interfered with. I was not in the least surprised when the
door was at last cautiously opened, and a woman who was a perfect
stranger to me stood on the threshold, with the handle of the
