Betty swung round again as the sound reached her ears and came face to face with Hanaud. Hanaud looked over her shoulder at Frobisher and shook his head ruefully.
"You did not find it, then?" Jim asked.
"No."
Hanaud looked away from Jim to Betty Harlowe.
"Monsieur Frobisher put an idea into my head, Mademoiselle. I had not looked into that exquisite Sedan chair. It might well be that the necklace had been hidden behind the cushions. But it is not there."
"And you locked the door, Monsieur," said Betty stiffly. "The door of my room, I ask you to notice."
Hanaud drew himself erect.
"I did, Mademoiselle," he replied. "And then?"
Betty hesitated with some sharp rejoinder on the tip of her tongue. But she did not speak it. She shrugged her shoulders and said coldly as she turned from him:
"You are within your rights, no doubt, Monsieur."
