CHAPTER XVIII
THE DUKE STAYS
THE Duke shut the door and leant against it, listening anxiously, breathing quickly. There came the bang of the front door. With a deep sigh of relief he left the door, came briskly, smiling, across the room, and put the card-case back into the pocket of Guerchard's cloak. He lighted a cigarette, dropped into an easy chair, and sat waiting with an entirely careless air for the detective's return. Presently he heard quick footsteps on the bare boards of the empty room beyond the opening. Then Guerchard came down the steps and out of the fireplace.
His face wore an expression of extreme perplexity:
"I can't understand it," he said. "I found nothing."
"Nothing?" said the Duke.
"No. Are you sure you saw the handkerchief in one of those little rooms on the second floor—quite sure?" said Guerchard.
