Antoine was fiercely indignant.

“But, Monsieur!” he exclaimed. “I do not understand! Examine my rooms? But it is impossible! Who dares to say that I harbor criminals?”

“I have information upon which I can rely,” John Dory answered, firmly. “This comes from a man who is no friend of mine, but he is well-known. You can read for yourself what he says.”

Monsieur Antoine, with trembling fingers, took the piece of paper from John Dory’s hands. It was addressed to—

Mr. JOHN DORY, DETECTIVE:

If you wish to find Jean Lemaitre, search in the upper rooms of the Hotel de Flandres. I have certain information that he is to be found there.

PETER RUFF.

“Never,” Antoine declared, “will I suffer such an indignity!”

Dory raised a police whistle to his lips.

“You are foolish,” he said. “Already there is a cordon of men about the place. If you refuse to conduct me upstairs I shall at once place you under arrest.”
