"I'll catch him yet," said Brissard, running towards the cloak room, "the fugitive must be bare-headed, he has not had time to get his hat. The address of his hatter may help us."

"Madame," asked he, addressing the woman in charge of the hats and cloaks, "has a gentleman with large moustachios just been here to get his hat?"

"No, sir."

"That will do. Take great care of the last hat which is not claimed, and keep it for me."

He then went on to the concierge.

"Tell me, have you just seen any one go out?"

"Yes, sir; a tall man, with big moustachios."

"That's he; and he was bare-headed?"

"Yes; but after going a few steps, he pulled out an opera hat from under his coat, and put it on his head."

"The rascal had made his arrangements beforehand," said Brissard. "We are done."
