our after hour and day after day, for a week the Sandra tracked on through the boundless leagues, the waxing sunlight beating steadily on her starboard bow and her silent gravity-plates and singing generators bringing Earth ever nearer. Friday, who possessed an extensive knowledge of all the practical sciences, did extra service in the role of cook, and his regularly served meals disguised the undifferentiated hours of space into Earth-mornings, noons and nights. Watch in and watch out, and nothing to disturb the even routine.

As for the ever-feared pursuit, there was no sign of it. Systematically and carefully the men stationed at the electelscope turned it through the region behind, but never did their watching eyes discern the bulk of the asteroid. Its disappearance, and the kindred mystery of who had been on it, remained unsolved.

Therefore peace came to Eliot Leithgow's face, and the tiredness left his eyes. The long, hunted years were beginning to be washed from him, and daily, to Carse, he appeared younger. Often in the control cabin or over a meal he talked of what lay ahead, and the happiness Earth held waiting for him. There was his daughter, Sandra, whom he had seen last as a girl of fourteen, and even then interested in his work. She would be matured now, and she would perhaps be eager to help him in the work he intended to resume. There was so much of it! Discoveries, theories, evolved during his fugitive years—now he could complete them and give them to his old circles of brother scientists. All this was in his conversations; but secret and unworded in his thoughts were anticipations of the old dear beauty of Earth, that beauty for which his ageing heart had pined so long....

And Earth was drawing nearer.

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.

here was no visible change in the five bodies. They lay stretched out in cots, sheets drawn up to their necks, and it seemed almost as if they were quietly slumbering and would presently wake up; though in reality consciousness would not return to the fine brains in their hideous, distorted bodies for many weeks, and then only if the healing processes were successful. Bandages swathed the heads, leaving eyes and nostrils alone visible. An assistant of Leithgow's, at present on watch there, moved occasionally with instrument in hand to time the fevered pulses.

"I must ask you to stand back here, Dr. Ku," said the Hawk, indicating a spot some five feet from the nearest cot. His left arm hung easily by his side, the hand resting by the butt of his holstered raygun; and the position was not accidental.

Ku Sui nodded and doubtless noted the gun, but his eyes were on the bodies. He stood regarding his own handiwork in silence, his face inscrutable, and Carse did not disturb him. At last, in a low tone he asked the assistant:

"The food injections take successfully?"

The man nodded.

"I remember," the beautifully modulated voice went on. "I was not sure of one subject. Swanson's brain, was it not? Is his condition any better?"

"We are not sure."

"Ah, yes ... yes...." He appeared to muse, and no one disturbed him in the minutes of silence that followed. Finally he looked away and said:

"It was a great feat. Thank you, Captain Carse. I am pleased by this glimpse of the miracle my hands were made to perform. I am ready to return."

But at the door of his cabin he paused, and his eyes rested again on the cold, firm face close to him. He said:

"I suppose, Captain Carse, you intend to bring me before Earth's World Court of Justice?"

"Yes. Along with our living proof of your abduction of the five scientists."

The Eurasian smiled. "I see. And since there is no questioning that proof, it would appear that Earthlings will soon levy punishment on Dr. Ku Sui.... So.... You know, Captain Carse, I find your caution a great handicap. You keep gassing me; I am locked in; and since I have observed no excitement aboard the ship, apparently there are no friends anywhere near me. You have stripped me of everything." His eyes lowered for a moment. "Everything save this ring."

On the forefinger of his right hand, set simply in a platinum band, was a large dark stone.

"A black opal," said Dr. Ku. "I have worn it for years and I prize it highly. Perhaps at the last I will give it to you as a memento of these past years, Captain Carse." And he went into the cabin, where they gassed him again.

he third week passed.

Crossing the orbit of Mars, now approximately in opposition to Jupiter, the Sandra streaked on into the last leg of her long voyage. The sun was a vast, flame-belching disk on her starboard side, and ahead lay Earth, growing each hour. Cheerfulness pervaded the ship, nerves were relaxing, faces lightening. Carse could not remember when Eliot Leithgow had worn a smile so constantly. It was only natural, for to the old scientist and his personal assistants Earth was home, the fulfillment of every desire, the reality and symbol of normal life and love of man.

But to Hawk Carse the Green Planet was not home. He was the adventurer, and wanderer, the seeker of new places with the alluring lustre of peril. Earth was to him little more than a port of call, and it brought him sadness to see how eagerly Leithgow stared at her growing face. Their parting was not far away now.

The Sandra logged off the miles. Then came the day when only ten thousand were left, and, soon after, five thousand. Deceleration had long since been begun. Slightly but unvaryingly the ship's momentum slackened until she arrived at the two thousand mile mark, where the great curving stretch of the planet filled her bow windows, and the well-remembered continents and seas stood out as clearly as on a tilted classroom globe.

Carse leaned musing in a corner of the control cabin, oblivious to the well-meaning but toneless voice with which Ban Wilson, at the electelscope was butchering a song. A gentle tap on the shoulder summoned him out of his study.

He turned and saw that Leithgow had come to him. Carse smiled at the old scientist, and said:

"Well, Eliot, we'll be in soon now. Apparently we've made it safely, and there's nothing to stand between you and the day you've waited for so long."

es. But Carse—what of you? How long will you stay? I only wish I could persuade you—"

"To retire, Eliot? Settle down? Become a humdrum landlocked Earthling?" He chuckled, and shook his head. "No, no, old friend. Oh, I'll stay on Earth for a few weeks; I suppose I'll have to, to testify before the World Court of Justice when it takes up your case; but after that's settled, I'll be going back. You know me, Eliot: I'll never change. There are a number of things I must attend to at once. My ship, the Star Devil, is still on Iapetus, remember; I must find her and get her tuned up again. She's the fastest craft in space, bar none. Then I must make the round of my ranches and see that things are running smoothly. I've a lot of work on the Iapetus ranch, particularly. Then, there's that Pool of Radium—not that I need the wealth, if it really exists; but the job has killed so many who have sought for it that I'd like to take a crack at it myself. Oh, plenty to do!"

Leithgow looked at him, and there was all affection in his eyes, and friendship as close as it can be between men.

"No, Carse," said Leithgow softly. "I suppose Earth will never get her gravity on you for keeps. But I hope you will come down occasionally to see me, and perhaps once a year, say, spend a month with Sandra and me in our—"

"Carse!"

Ban shouted the name out. His face, turned from the electelscope, was alive with excitement.

"Here! Look!"

"What is it?"

"The asteroid! It's close!"

In two strides Carse was at the eyepiece of the infra-red glass attached to the instrument. One look through it served to verify Ban's report. The asteroid of Dr. Ku Sui had at last appeared.

t was not more than fifty miles from the Sandra, a craggy fragment of rock, peanut-shaped, and tipped by its gleaming dome. Its speed seemed the same as theirs, but its course was different; and to Carse, that fact immediately explained its sudden appearance. He turned from the eyepiece with a face grown hard and cold.

"Well, it's happened," he said. "Instead of a stern chase, which would give us some chance of spotting them, they at once got off to the side and have all this time been flanking us. Now they're cutting in, straight behind, no doubt ready for business. All right. Ban, sound the alarm."

Like a gladiator about to step sword in hand into the arena, the Sandra, though a ship never designed for space duels, girded her loins and made herself ready for what at its best could only be an unequal struggle. She was outclassed in weapons, weight and speed—in all save pilots. She had Hawk Carse at her helm.

The harsh alarm bell at once rang through the ship, an emergency call to stations. Carse, at the controls, rapped out another order.

"Defensive web on, Ban, and build up power for the ray batteries."

As the echoes of the bell died, a piercing whine grew amidships, and shreds of blue light swiftly scattered by the Sandra's ports. They were quickly gone, but they left behind an almost invisible envelope of blue which enwrapped the ship completely. The defensive web against attacking rays was on.

Friday tumbled into the control cabin, and on his heels two of Leithgow's assistants, the third being on duty with the patients. Carse briefly explained what had happened. "Friday," he ordered, "you take the stern ray batteries. Ban—"

But Ban Wilson had returned to the electelscope, and it had given him more news. Interrupting, he cried out:

"They must be attacking! A light just flashed in the dome!"

With his words they all saw the light. The visi-screen, though it did not reveal the asteroid, showed the first weapon with which it struck—a lustrous ray of purple which in a blink had leaped out to the Sandra and enfolded her. A shower of sparks crackled out from the ship's defensive web, but the purple ray continued.

"I don't know that ray, Eliot." Carse said. "What's on our speed indicator?"

The scientist's gasp was plainly audible as he read the dial. "Why, it—it's dropping! Much faster than our deceleration accounts for! That ray—why, it must have magnetic properties! Carse, the asteroid's stopping us!"
