"Come, Francine!" she said, pronouncing her words like a person with an impediment of speech. "We must show Monsieur Hanaud that we are not the cowards he takes us for."

But Francine still held back.

"I don't understand at all. I am only a poor girl and this frightens me. The police! They set traps—the police."

Hanaud laughed.

"And how often do they catch the innocent in them? Tell me that, Mademoiselle Francine!"

He turned almost contemptuously towards Mrs. Harlowe's bedroom. Betty and Francine followed upon his heels, the others trooped in behind, with Frobisher last of all. He indeed was as reluctant to witness Hanaud's experiment as the girls were to take a part in it. It savoured of the theatrical. There was to be some sort of imagined reproduction of the scene which Ann Upcott had described, no doubt with the object of testing her sincerity. It would really be a test of nerves more than a test of honesty and to Jim was therefore neither reliable nor fair play. He paused in the doorway to say a word of encouragement to Ann, but she was gazing again with that curious air of perplexity at the clock upon the marquetry cabinet.

"There is nothing to fear, Ann," he said, and she withdrew her eyes from the clock. They were dancing now as she turned them upon Frobisher.

"I wondered whether I should ever hear you call me by my name," she said with a smile. "Thank you, Jim!" She hesitated and then the blood suddenly mounted into her face. "I'll tell you, I was a little jealous," she added in a low voice and with a little laugh at herself as though she was a trifle ashamed of the confession.

Jim was luckily spared the awkwardness of an answer by the appearance of Hanaud in the doorway.

"I hate to interrupt, Monsieur Frobisher," he said with a smile; "but it is of a real importance that Mademoiselle should listen without anything to distract her."
