“Sign it,” he urged. “Sign it in your own interests—and in hers.”

“Why in hers?”

“I shall shout murder, and alarm the police,” I threatened.

“Shout away, my dear fellow,” replied my captor. “No sound can be heard outside this room. Shriek! We shall like to hear you. You won’t have opportunity to do so very much longer.”

“Why?”

“Because refusal will bring upon you a fate more terrible than you have ever imagined,” was the fellow’s hard reply. “We are men of our word, remember! It is not wise to trifle with us.”
