The cab proceeded on its way and stopped at the Coq-Faisan. Georges entered the dining-room and ate slowly, looking at his watch from time to time. At seven-thirty he left and drove to Rue La Rochefoucauld. He mounted to the third story of a house in that street, and asked the maid who opened the door: "Is M. Guibert de Lorme at home?"
"Yes, sir."
He was shown into the drawing-room, and after waiting some time, a tall man with a military bearing and gray hair entered. He was the police commissioner.
Du Roy bowed, then said: "As I suspected, my wife is with her lover in furnished apartments they have rented on Rue des Martyrs."
The magistrate bowed: "I am at your service, sir."
"Very well, I have a cab below." And with three other officers they proceeded to the house in which Du Roy expected to surprise his wife. One officer remained at the door to watch the exit; on the second floor they halted; Du Roy rang the bell and they waited. In two or three minutes Georges rang again several times in succession. They heard a light step approach, and a woman's voice, evidently disguised, asked:
"Who is there?"
The police officer replied: "Open in the name of the law."
The voice repeated: "Who are you?"
"I am the police commissioner. Open, or I will force the door."
