M. Verduret did not reply, but walked toward a young man dressed like a brewer, who had just entered the room.

He glanced at the note which this person handed to him, and hastened back to the table, and said, in an agitated tone:

“I think we have got them now!”

Throwing a five-franc piece on the table, and without saying a word to Cavaillon, he seized Prosper’s arm, and hurried from the room.

“What a fatality!” he said, as he hastened along the street: “we may miss them. We shall certainly reach the St. Lazare station too late for the St. Germain train.”

“For Heaven’s sake, where are you going?” asked Prosper.

“Never mind, we can talk after we start. Hurry!”

Reaching Palais Royal Place, M. Verduret stopped before one of the hacks belonging to the railway station, and examined the horses at a glance.

“How much for driving us to Vesinet?” he asked of the driver.

“I don’t know the road very well that way.”
