"M. Formery's orders?" said the Duke, standing on the top step. "Call me a taxi-cab, please."
The concierge, who stood beside the policeman, ran down the steps and blew his whistle. The policeman gazed uneasily at the Duke, shifting his weight from one foot to the other; but he said no more.
A taxi-cab came up to the door, the Duke went down the steps, stepped into it, and drove away.
Three-quarters of an hour later he came back, having changed into clothes more suited to a Paris drawing-room. He went up to the drawing-room, and there he found Guerchard, M. Formery, and the inspector, who had just completed their tour of inspection of the house next door and had satisfied themselves that the stolen treasures were not in it. The inspector and his men had searched it thoroughly just to make sure; but, as Guerchard had foretold, the burglars had not taken the chance of the failure of the police to discover the opening between the two houses. M. Formery told the Duke about their tour of inspection at length. Guerchard went to the telephone and told the exchange to put him through to Charmerace. He was informed that the trunk line was very busy and that he might have to wait half an hour.
