A group of horsemen suddenly appeared on the Square. Robeccal and Cyprien were with them.
When Robeccal went away, he had taken the precaution to leave a window open on the lower floor, which Schwann had not discovered in making his rounds for the night.
Robeccal entered through this window and opened the door.
Schwann was aroused by footsteps below, and rushed down the stairs. Seeing the police in uniform, he uttered an exclamation.
"The police in my house!" he cried.
"I ask your pardon, sir," answered the Brigadier of police, "but there was urgent need. In the name of the king!"
Schwann repeated the words with a sigh.
"You have conspirators lodging here—enemies of the monarchy!"
"You are greatly mistaken, Brigadier—"
"Not so. Their names are Gudel and Fanfar."
