Mr. Sabin looked thoughtful.

“It is only necessary,” he said, “for me to be in the room for about ten minutes, and I do not need to carry anything away; my memory will serve me for all that I require. By some means or other I must have that ten minutes.”

“You will risk your life,” Lady Deringham said, “for I cannot suggest any plan; I would help you if I could, but I am powerless.”

“I must have that ten minutes,” Mr. Sabin said slowly.

“Must!” Lady Deringham raised her eyebrows. There was a subtle change in the tone of the man, a note of authority, perhaps even the shadow of a threat; he noted the effect and followed it up.

“I mean what I say, Constance,” he declared. “I am not asking you a great thing; you have your full share of woman’s wit, and you can arrange this if you like.”

“But, Victor, be reasonable,” she protested; “suggest a way yourself if you think it so easy. I tell you that he never leaves the room!”

“He must be made to leave it.”

“By force?”

“If necessary,” Mr. Sabin answered coolly.
