arm go about the trim figure of Diane Delacouer. No mannish attire could disguise Diane's charms; nor could nerve and cold courage that any man might envy detract from her femininity. Her dark, curling hair was blowing back from her upraised face as the scented breezes played about her; and the soft beauty of that face was enhanced by the very starlight that revealed it.
It was here that Walt and Diane had learned to love; what wonder that the fragrant night brought only remembrance, and forgetfulness of their present plight. But Chet Bullard, while he saw them and smiled in sympathy, knew suddenly that other eyes were watching, too; he felt the bulky figure of Herr Schwartzmann beside him grow tense and rigid.
But Schwartzmann's voice, when he spoke, was controlled. "All right," he called toward the ship; "all iss safe."
Yet Chet wondered at that sudden tensing, and an uneasy presentiment found entrance to his thoughts. He must keep an eye on Schwartzmann, even more than he had supposed.
Their captor had threatened to maroon them on the Dark Moon. Chet did not question his intent. Schwartzmann would have nothing to gain by killing them now. It would be better to leave them here, for he might find them useful later on. But did he plan to leave them all or only two? Behind the steady, expressionless eyes of the Master Pilot, strange thoughts were passing....

There were orders, at length, to return to the ship. "It is dark already," Schwartzmann concluded; "nothing can be accomplished at night.
"How long are the days and nights?" he asked Harkness.
"Six hours." Harkness told him; "our little world spins fast."
"Then for six hours we sleep," was the order. And again Herr Schwartzmann conducted Mademoiselle Delacouer to her cabin, while Chet Bullard watched until he saw the man depart and heard the click of the lock on the door of Diane's room.
Then for six hours he listened to the sounds of sleeping men who were sprawled about him on the floor; for six hours he saw the one man who sat on guard beside a light that made any thought of attack absurd. And he cursed himself for a fool, as he lay wakeful and vainly planning--a poor, futile fool who was unable to cope with this man who had bested him.
Nineteen seventy-three!--and here were Harkness and Diane and himself, captured by a man who was mentally and morally a misfit in a modern world. A throw-back--that was Schwartzmann: Harkness had said it. He belonged back in nineteen fourteen.
Harkness was beyond the watching guard; from where he lay came sounds of restless movement. Chet knew that he was not alone in this mood of hopeless dejection. There was no opportunity for talk; only with the coming of day did the two find a chance to exchange a few quick words.
* * * * *
The guard roused the others at the first sight of sunlight beyond the ports. Harkness sauntered slowly to where Chet was staring from a lookout. He, too, leaned to see the world outside, and he spoke cautiously in a half-whisper:
"Not a chance, Chet. No use trying to bluff this big crook any more. He's here, and he's safe; and he knows it as well as we do. We'll let him ditch us--you and Diane and me. Then, when we're on our own, we'll watch our chance. He will go crazy with what he finds--may get careless--then we'll seize the ship--" His words ended abruptly. As Schwartzmann came behind them, he was casually calling Chet's attention to a fumerole from which a jet of vapor had appeared. Yellowish, it was; and the wind was blowing it.
Chet turned away; he hardly saw Schwartzmann or heard Harkness' words. He was thinking of what Walt had said. Yes, it was all they could do; there was no chance of a fight with them now. But later!
Diane Delacouer came into the control-room at the instant; her dark eyes were still lovely with sleep, but they brightened to flash an encouraging smile toward the two men. There were five of Schwartzmann's men in the ship besides the pilot and the scientist, Kreiss. They all crowded in after Diane.
They must have had their orders in advance; Schwartzmann merely nodded, and they sprang upon Harkness and Chet. The two were caught off their guard; their arms were twisted behind them before resistance could be thought of. Diane gave a cry, started forward, and was brushed back by a sweep of Schwartzmann's arm. The man himself stood staring at them, unmoving, wordless. Only the flesh about his eyes gathered into creases to squeeze the eyes to malignant slits. There was no mistaking the menace in that look.
* * * * *
"I think we do not need you any more," he said at last. "I think, Herr Harkness, this is the end of our little argument--and, Herr Harkness, you lose. Now, I will tell you how it iss that you pay.
"You haff thought, perhaps, I would kill you. But you were wrong, as you many times have been. You haff not appreciated my kindness; you haff not understood that mine iss a heart of gold.
"Even I was not sure before we came what it iss best to do. But now I know. I saw oceans and many lands on this world. I saw islands in those oceans.
"You so clever are--such a great thinker iss Herr Harkness--and on one of those islands you will haff plenty of time to think--yess! You can think of your goot friend, Schwartzmann, and of his kindness to you."
"You are going to maroon us on an island?" asked Walt Harkness hoarsely. Plainly his plans for seizing the ship were going awry. "You are going to put the three of us off in some lost corner of this world?"
Chet Bullard was silent until he saw the figure of Harkness struggling to throw off his two guards. "Walt," he called loudly, "take it easy! For God's sake, Walt, keep your head!"
This, Chet sensed, was no time for resistance. Let Schwartzmann go ahead with his plans; let him think them complacent and unresisting; let Max pilot the ship; then watch for an opening when they could land a blow that would count! He heard Schwartzmann laughing now, laughing as if he were enjoying something more pleasing than the struggles of Walt.

Chet was standing by the controls. The metal instrument-table was beside him; above it was the control itself, a metal ball that hung suspended in air within a cage of curved bars.
It was pure magic, this ball-control, where magnetic fields crossed and recrossed; it was as if the one who held it were a genie who could throw the ship itself where he willed. Glass almost enclosed the cage of bars, and the whole instrument swung with the self-compensating platform that adjusted itself to the "gravitation" of accelerated speed. The pilot, Max, had moved across to the instrument-table, ready for the take-off.
Schwartzmann's laughter died to a gurgling chuckle. He wiped his eyes before he replied to Harkness' question.
"Leave you," he said, "in one place? _Nein!_ One here, the other there. A thousand miles apart, it might be. And not all three of you. That would be so unkind--"
He interrupted himself to call to Kreiss who was opening the port.
"No," he ordered: "keep it closed. We are not going outside; we are going up."
But Kreiss had the port open. "I want a man to get some fresh water," he said; "he will only be a minute."
He shoved at a waiting
