nother week passed.

Twice a day the door of Dr. Ku Sui's cabin was unlocked and he was brought out under guard for several turns through the ship. Though for safety's sake they continued to dose him with the V-27, it was apparent that the gas had less and less effect on him. Four, then eight, then twelve times a day they re-gassed him—as often as they dared, considering its ultimate destructive mental effect—but more and more of the frankness and serenity foreign to his green eyes melted away. Gradually the normal veil came to hide their depths and make them enigmatic; and sometimes there was again on his face the hint of something strong and tigerish and cruel lying waiting. They no longer trusted him to attend to the five patients. He spoke seldom. A tall, reserved figure in black silk, attended either by Ban Wilson or Friday, he strolled through the ship for fifteen minutes and was returned to his lonely cabin. Of all the marks his experience must have left upon him, the only one apparent was his silence.

It was on the seventeenth day that he forsook that silence and directly accosted Carse. He had a request. The saffron face impassive, the long lashes lying low over the eyes, he said softly:

"I wonder, Captain Carse, if I might be permitted a glimpse of the subjects of my transplantation?"

Leithgow and Wilson were at the time with Carse in the control cabin, and they regarded their friend intently, curious as to what the reply would be. They saw his steel-gray eyes meet Dr. Ku's gaze squarely; and the two men looked at each other: Hawk Carse, complete victor at last, and Ku Sui, the vanquished.

The adventurer answered:

"Your request is only natural, Dr. Ku. Certainly you may see them, and perhaps offer an opinion on their progress, which has so far been in the hands of your assistants. But I shall have to accompany you."

"You are kind."

"Take the controls, Ban," Carse directed, and together they left the cabin.
