The Passing of Ku Sui Part 7

At that the Eurasian laughed aloud, a liquid laugh that showed his even teeth between the finely cut lips.

"But I am so completely in your power, Captain Ca.r.s.e!" He held on to the last syllable, a low, sustained hiss--and then he snapped it off.

"_S-s-stah!_" His mood had changed: the smile vanished from a face suddenly thin and cruel; the green eyes unmasked, to show in their depths the tiger.

"What insane talk! You say such things to me! Don't you know that to coordinate those brains I worked for years with a devotion, a concentration, a genius you can never hope even to comprehend? Don't you realize they're the most precious possession of the greatest surgeon and the greatest mind in the universe? Don't you understand that I've fashioned a miracle? Realize these things, then, and marvel at yourself--you who, with your gun and your egotism, think you can make me undo their wonderful coordination!"

The tiger returned behind the veil, its power and fury again leashed, and Dr. Ku Sui relaxed his green eyes once more masked and enigmatic.

Hawk Ca.r.s.e asked simply:

"_Could_ you transplant the brains?"

"You insist on continuing this farce?" murmured the Eurasian. "I would not be rude, but really you try my patience!"

"_Could_ you transplant the brains?"

Dr. Ku Sui looked at the colorless face with its eyes of ice. With a trace of irritation, he said:

"Of course! What I have once transplanted, I can transplant again. But I will not do it--and my will no one, and no force, can alter. Perhaps it is clear now? In no way can you touch my will. I am sorry that I so grossly insulted you, Ca.r.s.e, for there are certain things about you that in a small way I respect. But here you are helpless."

"Not entirely," said the Hawk.

Ku Sui leaned forward a trifle. In that moment, perhaps, he first felt real concern, for Ca.r.s.e's quiet voice was so confident, so a.s.sured. He attempted to sound him out.

"A gun?" he asked. "Torture? Threats? These against my will? Absurd!

Consider, my friend--even if I seemed to consent to the operations, could I not easily destroy the brains while ostensibly working on them?"

"Of course," said Ca.r.s.e, with a faint smile. "And threats and torture would be absurd. Against your will, Dr. Ku, a more powerful weapon will have to be used."

The Eurasian's eyes were brilliant with intuition.

"Ah--I see," he murmured. "Eliot Leithgow!"

"Yes, Dr. Ku!"

The two gazed at each other, Ca.r.s.e still with the faint smile, the other with the face of a statue. Presently the adventurer went on:

"Unfortunately for you, Eliot Leithgow can provide a method of compulsion neither you nor any other man could ever resist. Not guns, torture, threats--no. A subtler weapon, worthy of your fine will."

As he spoke, Ca.r.s.e saw the Eurasian's green eyes narrow, and in the pause that followed he knew that the swift, trained mind behind those eyes was working. What would it evolve? What move? And those Chinese words, uttered out by the port-lock--what would they result in, and when? Dr. Ku Sui was concerned now, the Hawk knew, seriously concerned, and inevitably, would take serious steps. What was growing in his resourceful brain? He would have to ward off any trouble when it came, for he could not know now. He said curtly:

"But enough of that. Now, I have a trifling favor to ask of you--something concerning the laboratory. Will you please return to it."

A strange light glimmered for an instant in Dr. Ku Sui's eyes--a mocking of the slender man before him. Only for an instant; then it was gone. Gracefully he raised his tall figure.

"The laboratory? Of course, my friend. And as for the favor--almost anything."

CHAPTER VI

_The Deadline_

Friday greeted them with another wide grin, and would again have bludgeoned the Eurasian with his wit had not the Hawk motioned him to silence. Looking at Dr. Ku, he said:

"I have Friday posted here because of the secret panel somewhere in this wall. You escaped through it before--do you remember?"

"Of course I remember. And if I'd had merely a fraction of your luck then, my present situation would be quite different."

"Perhaps," said the Hawk. "This panel is now the unknown quant.i.ty so far as I'm concerned, and I don't like unknown quant.i.ties; so I am asking you to show me where it is and how it works. That's my favor.

Of course you can refuse to reveal it, but that will not delay me very long. The method of compulsion I mentioned...."

Dr. Ku-Sui appeared to reflect a moment, but his decision was not tardy in coming. He smiled.

"You terrify me, Captain, with your ominous hints about compulsion. I suppose I'd better be reasonable and show it to you. Really, though, your concern over the panel is rather wasted, inasmuch as it conceals nothing more than a small escape pa.s.sage leading out of this building.

Nothing important at all."

But his words, Ca.r.s.e somehow felt, were a screen; something else lay beneath them. He watched the tall figure with its always present odor of tsin-tsin blossoms move forward in a few indecisive steps, then back again, considering. The smile and the easy words were a camouflage, surely--but for what?

"Nothing important at all." Dr. Ku Sui repeated pleasantly. "Come. I will show you. Friday--if I may so address you--over on that switchboard you will find a small lever-control. It is the one with a Chinese character above it. Will you be so kind as to throw it?"

The Negro glanced inquiringly at his master. Grimly Ca.r.s.e nodded.

An enigmatic light glimmered in the Eurasian's green eyes as they watched the Negro go to the switchboard and put thumb and forefinger on the control.

"Only a small escape pa.s.sage," he said deprecatingly as the Hawk crouched, gun ready, his eyes on the suspected place in the wall.

Friday threw the switch.

Immediately there sounded a short, sharp explosion. And acrid smoke billowed out from under the case of coordinated brains!

Ca.r.s.e 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 a.s.surance, 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.'"
