Smiling pleasantly, he stole to the window and looked out.

His eyes brightened at the sight of the motor-car, Guerchard's car, waiting just before the front door and in charge of a policeman.

He stole to the head of the stairs, and looked down into the hall.

Victoire was sitting huddled together on a chair; Sonia stood beside her, talking to her in a low voice; and, keeping guard on Victoire, stood a brown-faced, active, nervous policeman, all alertness, briskness, keenness.
"Hi! officer! come up here! Be smart," cried Lupin over the bannisters, in the husky, gentle voice of Chief-Inspector Guerchard.
The policeman looked up, recognized the great detective, and came bounding zealously up the stairs.
Lupin led the way through the anteroom into the sitting-room.

Then he said sharply: "You have your revolver ?" "Yes," said the young policeman.
