"He is very rich," said Langholm, repressing by main force a desire to ask a string of questions. He fancied that the porter was not one who needed questioning, and his patience had its immediate reward.

"I remember when he arrived," the man went on. "It was late at night, and he hadn't ordered his room. He came in first to see whether we could give him one. I paid the cab myself and brought in his bag."

"He had just arrived from the country, I presume?"

The porter nodded.

"At King's Cross, by the 10.45, I believe; but it must have been a good bit late, for I was just coming off duty, and the night-porter was just coming on."

"Then you didn't see any more of Mr. Steel that night?"

"I saw him go out again," said the porter, dryly, "after he had something to eat, for we are short-handed in the off-season, and I stopped up myself to see he got it. I didn't see him come in the second time."

Langholm could hardly believe his ears. To cover his excitement he burst out laughing.

"The old dog!" he cried. "Do you know if he ever came in at all?"

"Between two and three, I believe," said the porter in the same tone.
