"Monsieur de Courtois is a friend of mine," came the sullen response.

"Oh, is he? Then you do know something about events in 27th Street, eh?"

"I tell you nothing, but why should I deny that I know Monsieur de Courtois?"

"Or that you are a Frenchman," put in Curtis quietly. "One of the few words in the French language which no foreigner can ever pronounce is that word 'Monsieur,' especially when it is followed by a 'de.' I speak French well enough to realize my limitations."

"Now, Anatole, cough it up," said McCulloch jocularly. "You've no more chance of winning through than a chunk of ice in hell's flames."

"Let me alone, I'm tired," said the other, relapsing into a stony inattention which did not end even when Brodie brought the car to a stand outside the police station-house in West 30th Street.

The advent of the roundsman with a prisoner and escort created some commotion among his colleagues. The police captain was the same official who had harbored suspicion against Curtis not so many hours ago, and his opinion was not entirely changed, only modified.

He glanced darkly at Curtis and Devar, but was manifestly cheered by sight of McCulloch with a chauffeur in custody.

"Hello!" he cried, "and where in Hades have you been?"

"A long way from home, Mr. Evans," said the roundsman. "But it was worth while. This is Anatole, whose other name is Labergerie, the man wanted for the murder in 27th Street."
