"Don't you like wild country?" laughed Coquenil. "I do." It was plain that his spirits were reviving.
They ran along this rough way for several miles, and presently came to a small house standing some distance back from the road.
"Stop here!" ordered the detective. "Now," he turned to Pougeot, "I shall learn something that may fix my decision." Then, leaning forward to the chauffeur, he said impressively: "Ten francs extra if you help me now."
These words had an immediate effect upon the man, who touched his cap and asked what he was to do.
"Go to this house," pointed M. Paul, "ring the bell and ask if there is a note for M. Robert. If there is, bring the note to me; if there isn't, never mind. If anyone asks who sent you, say M. Robert himself. Understand?"
"Oui, m'sieur," replied the chauffeur, and, saluting again, he strode away toward the house.
The detective watched his receding figure as it disappeared in the shadows, then he called out: "Wait, I forgot something."
The chauffeur turned obediently and came back.
"Take a good look at him now," said Coquenil to Tignol in a low tone. Then to the man: "There's a bad piece of ground in the yard; you'd better have this," and, without warning, he flashed his electric lantern full in the chauffeur's face.
"Merci, m'sieur," said the latter stolidly after a slight start, and again he moved away, while Tignol clutched M. Paul's arm in excitement.
