The points of light moved on the screen and the three men watched with a concentration of interest which argued of some anxiety. None of them made any move to touch the levers or buttons on the panel. Dane wriggled on his belly towards a point from which he could overhear any orders Rich might give. So he was flattened out of sight a few minutes later when the sound of running feet startled him. Someone was coming through the maze. It was one of the outlaws and he wove a path from the crooked hall to angled room in a manner which proved that he knew the secret. As he came up against the barrier he threw back his head and shouted, his voice ringing in the vast dome over their heads:
“Salzar!”
Rich whirled and then he flung out his right hand and made some adjustment on the panel. A section of the wall slid back to admit the newcomer.
Rich’s voice, chilly with irritation, floated up to the watcher above:
“What’s the matter?”
The runner was still puffing, his beefy face showing flushed. “Message from Algar, chief. He’s coming in-with the Patrol riding his fins!”
“Patrol!” the man at the keyboard half turned in his chair, his mouth slightly agape.
“Did you warn him that the pull was on?” demanded Rich.
“Sure we did. But he can’t evade much longer. He either earths or the Patrol nets him-”
Rich stood very still, his head slightly cocked so that he could see the vision plate. His other assistant, the Rigellian, spoke first:
“Always said we needed a com hook-up down here,” he stated, with some of the content of one who is at last proved to be right in a long argument.
The man at the controls had a quick answer for that. “Yes-and how are you going to cut through the interference to hear anything over it?” he began when Rich snapped an order to the messenger:
“Get back up there and tell Jennis to order Algar to go inert at once. In exactly two hours,” he was consulting his watch, “we’ll off the pull for an hour-an hour, that’s all. He’s to set down, make the best landing he can under power. It doesn’t matter if he smashes the ship-he’ll work to save his own skin all right. Then we’ll snap on the power and net the Patroller when she comes in for the kill. Get it?”
“Two hours and then off pull-keep it off for one, and he’s to make a landing then-then on pull,” parroted the messenger. “Got it!”
He turned and pounded out of the room, back into the maze. For a moment Dane longed to be twins so that he might follow that flight and so find the way out of the puzzle. But it was more important now to see how Rich was going to manipulate the installation to neutralize the power for the landing of his subordinate’s ship.
“Think he’ll make it?” asked the man at the control board.
“Twelve to two he does,” snapped the Rigellian. “Algar’s a master pilot.”
“He’ll have to take the pull coming in and be ready to snap on his braking rockets the minute it fades-tricky stuff-” It was plain that the other was dubious.
Rich was still watching the vision plate. Two new lights appeared on its surface. But their fluttering across it was so erratic that Dane, not being briefed on the use of this alien recorder, could make nothing of that weird dance.
Rich’s lips were moving, counting off seconds, his eyes going from his watch to the plate and back again. The atmosphere grew more tense. At the control board the man’s shoulders were hunched, his attention glued to the row of buttons at his finger tips. While the Rigellian strode with the peculiar gliding walk of his kind to the far end of the wall panel, his scaled, bluish six-fingered hand outstretched to one lever there.
“Wait-!” It was the man at the keyboard. “It’s pulsing again-!”
Rich spat a blistering oath. On the screen the dots were moving up and down in a crazy race. And Dane was conscious that the hum of the installation varied, that the beat had developed a tripping accent.
“Get it back!” Rich sped to the keyboard. “Get it back!”
The man showed a face damp with sweat. “How can I?” he demanded. “We don’t know why it does this.”
“Shorten the beam-that helped once before,” that was the Rigellian. Of the three he showed the least emotion.
The man pressed two buttons. All three stared at the screen for the results of that move. The wildly flying dots settled down to a pattern not far different from the one they had made when Dane had first come upon the scene.
“How far out does it pull now?” asked Rich.
“Atmosphere level.”
“And the ships?”
His underling squinted at the board and consulted some dials. “They won’t come into the pull for one-maybe two hours. When we cut like that it takes time to build up the power again. Anyway this doesn’t affect that blasted trader any-she can’t lift.”
Rich took a small box from his pocket, poured some of its contents into the palm of his hand and licked it up. “It is pleasant to know that something is going right,” he observed with a chill in his voice which made Dane’s skin prickle.
“We don’t know much about this,” the man thumbed the edge of the keyboard. “None of us has been trained to use it right. And it was alien made to begin with-”
“Let me know when and if you can get it back on full power again,” was all the answer Rich made.
Two hours before they could turn on the full power, Dane thought. Now if in those two hours he and Mura-and maybe Kosti and Ali-could move-that lever the Rigellian had reached for-it must control something important. And if they could take over this room and the men in it, they would learn even more about its operation. Suppose the Patrol ship could make a safe landing on the tail of the outlaw they were pursuing-! What should be his next move?
Rich decided it for him. His jaws moving in a rhythmical chewing, the outlaw leader walked towards the hidden door. “You say two hours,” he spoke over his shoulder as he went. “It’ll be much better all around if you halve that, understand? I’ll be back in an hour-be ready to cut in the full beam then.” He nodded curtly to the Rigellian and stepped through the opening in the wall.
And this time Dane was ready to follow. He allowed Rich a good start and trailed the other through the winding ways which the outlaw threaded with the ease of much practice. Before they had drawn level with the small beacon provided by Mura’s torch, a beacon Rich could not sight from the floor, Dane had the secret of the maze. Two right turns, then one left, and then three right once more, skip the next passage opening and repeat. Rich had made the same pattern four times and Dane was sure that it would continue to carry him to the outer door of the puzzle. But, having learned that, the Trader waited on the wall for the other to work his way five corridors ahead before he crossed to the room where he had left Mura and Ali.
He found Kamil up and walking about now, restored by the steward’s first aid. And as Dane climbed down their crude ladder they closed in on him.
“-That’s it,” he ended his report. “The Patrol’s riding in on this bird’s jet stream. As long as they both stay out of the atmosphere they’re safe. But once the pull is working full power again-” he snapped his fingers.
“Our move!” Kamil got out the words between his swollen lips. “We’ve got to cut that power off-totally!”
“Yes,” Mura crossed to the holds on the wall. “But first we collect Kosti-”
“How can you get him here? He said he can’t walk the walls-”
“A man can do anything if he is forced to it,” Mura replied. “You will stay here-I shall bring Kosti. But first show me the route which takes one to this ‘heart’-”
Dane reclimbed the wall behind the steward, led the way across the three intervening spaces to that corridor he had seen Rich traversing. And there he repeated the pattern the outlaw had followed. Mura smiled his placid smile.
“It is very simple, is it not? Now, you wait with Kamil-and do nothing foolish until I return. This is most interesting-”
Dane obediently went back to the room where they had left the engineer-apprentice. Kamil sat on the floor, his back against one of the walls, his battered face turned to the torch light. As Dane’s boots hit the pavement he turned his head.
