The Hawk looked at him for a minute. Then silently he obeyed. He knew that the Eurasian would have no compunctions about shooting him down in cold blood; but, on the other hand, even as the man had said, he could not kill Ku Sui, but had to capture him, in order to take him to Earth to confess to crimes now blamed on Eliot Leithgow. "Do as he says, Friday," he instructed the still staring negro; and, like a man in a trance, Friday obeyed.
"Thank you," the Eurasian said. "It was a most friendly thing to do." He paused. "I suppose you are wondering how I arrived here, and why you did not see me come. Well, I shall certainly tell you, in return for your favor. But first—ah, friend Carse—your gesture! A reminder, I assume."
Slowly the Hawk was stroking the bangs of hair which had been trained to obscure his forehead. There was no emotion on his chilly face as he answered, no slightest sign of feeling unless it were a slight trembling of the left eyelid—significant enough to those who could read it.
"Yes," he whispered, "a reminder. I do not like to wear my hair like this, Ku Sui, and I want you to know that I've not forgotten; that, though I'm now in your power, there'll be a day——"
"But you wouldn't threaten your host!" the other said with mock surprise. "And surely you wouldn't threaten me, of all men. Must I point out how useless it has always been for you to match yourself, merely a skilful gunman, against me, against a brain?"
"Usually," the cold whisper came back, "the brain has failed in the traps it has laid for the gunman."
"Only because of the mistakes of its agents. Unfortunately for you, the brain is dealing with you directly this time, my friend. It's quite a different matter. But this small talk—although you honor——"
"Of course you intend to kill me," said the Hawk. "But when?"
Dr. Ku gestured deprecatingly. "You insist on introducing these unpleasant topics! But to relieve your mind, I've not yet decided how I can entertain you most suitably. I have come primarily to ask you one trifling thing."
