"When did Crochard leave?" he asked.
"He gave me the note at four o'clock yesterday afternoon, sir, and stated that he was about to depart. I have not seen him since."
"Did he mention his destination?"
"No, sir."
Lépine regarded his companion thoughtfully.
"There is one thing that perhaps you can tell me, Samson," he said. "Previous to his departure, did he visit the house at 80 Rue du Plasson?"
"I think it very probable," answered Samson, after a moment's hesitation. "I myself furnished M. Crochard with that address, when he returned to the café yesterday for his lunch."
"Ah!" said Lépine. "So it was you discovered it!"
He fell a moment silent, studying the other's countenance.
"You have indeed changed, Samson," he said, at last. "I suppose it was Crochard who arranged your escape?"
