arse sprang to Ku Sui, gripped one arm and cried harshly:

"What have you done?"

"Not I, Captain—your obedient servant, the Black. Please, your fingers—" He removed them from his arm; and then, smiling, he said:

"I am afraid that all your assurance, your threats, are now but so much wasted breath."

"You mean—?"

"Surely, Captain," said Ku Sui, "you must have known I would provide for such an emergency, as this. I chose not to risk your darkly-hinted method of compulsion, and so had Friday remove the need for it. The Chinese character above the switch stands for 'Death.'"

Frigidly the Hawk asked: "You've destroyed the brains?"

"I have destroyed the brains." The Eurasian's voice was deep with a strange, unusual tone. "No matter: it was time. I am far, far ahead of that work, great though it was; it has destroyed itself with its inherent, irremediable fault. Yes, far ahead. Next time...." He appeared to lapse into profound and melancholy reflections; seemed to forget entirely the two men by him.
