When he came to himself again a machine was clicking erratically and there was the soft whine of machinery going somewhere. He opened his eyes and saw red all about him. He stirred, and he was free. Painfully, he sat up and blinked about him with streaming, gas-irritated eyes. He had been lying on a couch. He was in a room perhaps fifteen feet by twenty, of which the floor was slightly off-level. And everything in the room was red. Floor and walls and ceiling, the couch he had lain on and the furniture itself. There was a monstrous bulk of a man sitting comfortably in a chair on the other side of the room, pecking at a device resembling a writing-machine.
Thorn sat still for an instant, gaining strength. Then he flung himself desperately across the room, his fingers curved into talons.
Five feet, ten, with the slant of the floor giving him added impetus.... Then his muscles tightened convulsively. A wave of pure agony went through his body. He dropped and lay writhing on the floor, while the high-frequency currents of an induction-screen had their way with him. He was doubled into a knot by his muscles responding to the electric stimulus instead of his will. Sheer anguish twisted him. And the room filled with a hearty bellow of laughter. The monstrous whiskered man had turned about and was shaking with merriment.
He picked up a pocket-gun from beside him and turned off a switch at his elbow. Thorn's muscles were freed.
"Go back, my friendt," boomed the same voice that had come from a speaker the night before. "Go to der couch. You amuse me and you haff already been useful, but I shall haff no hesitation in killing you. You are Thorn Hardt. My name is Kreynborg. How do you do?"
"Where's my friend?" demanded Thorn savagely. "Where is she?"
"Der lady friendt? There!" The whiskered man pointed negligently with the pocket-gun. "I gafe her a bunk to slumber in."
There was a niche in the wall, which Thorn had not seen. Sylva was there, sleeping the same heavy, dreamless sleep from which Thorn himself had just awakened. He went to her swiftly. She was breathing naturally, though tears from the irritating gas still streaked her face and her skin seemed to be pinkened a little from the same cause.
Thorn swung around. His weapons were gone, of course. The huge man snapped on the induction-screen switch again and put down his weapon. With that screen separating the room into two halves, no living thing could cross it without either such muscular paralysis as Thorn had just experienced, or death. Coils in the floor induced alternating currents in the flesh itself, very like those currents used for supposed medical effects in "medical batteries," and "shockers."
