His diction was characteristic, resembling his carriage in that it was slow and distinctive. He seemed deliberately to choose each word and to give to it all its value, syllable by syllable. His English was perfect to the verge of the pedantic; and his voice was metallic and harsh, touching at time, when his words were vested with some subtle or hidden significance, guttural depths which betrayed the Chinaman. He possessed uncanny dignity as of tremendous intellect and conscious power.

"I regret that you were so rash as to take part in last night's abortive raid, Dr. Stuart," he said.

Stuart started. So he had been unconscious for many hour!

"Because of your professional acquirements at one time I had contemplated removing you," continued the unemotional voice. "But I rejoice to think that I failed. It would have been an error of judgement. I have useful work for such men. You shall assist in the extensive laboratories of my distinguished predecessor."

"Never!" snapped Stuart.

The man's callousness was so purposeful and deliberate that it awed. He seemed like one who stands above all ordinary human frailties and emotions.

"Your prejudice is natural," rejoined Fo-Hi calmly. "You are ignorant of our sublime motives, but you shall nevertheless assist us to establish that intellectual control which is destined to be the new World Force. No doubt you are conscious of a mental hiatus extending from the moment when you found the pigtail of the worthy Ah-Fang-Fu about your throat until that when you recovered consciousness in this room. It has covered a period roughly of twenty-four hours, Dr. Stuart."

"I don't believe it," muttered Stuart—and found his own voice to seem as unreal as everything else in the nightmare apartment. "If I had not revived earlier, I should never have revived at all."

He raised his hand to his swollen throat, touching it gingerly.

"Your unconsciousness was prolonged," explained Fo-Hi, consulting an open book written in Chinese characters, "by an injection which I found it necessary to make. Otherwise, as you remark, it would have been prolonged indefinitely. Your clever but rash companion was less happy."
