He went back to the torch and observed placidly, «The Professor ain’t around, is he?»
Tommy shook his head.
«Thought not,» said the red-headed one. «He gen’rally comes out and talks awhile. I helped him build some of them dinkuses in the barn yonder.»
Tommy said eagerly, «Say, which of those things did you help him build? That big thing with the solenoid-the coil?»
«Yeah. How’d it work?» The red-headed one set a soldering iron in place and began to jack up the rear wheel to get at the tire. «Crazy idea, if you ask me. I told Miss Evelyn so. She laughed and said she’d be in the ball when it was tried. Did it work?»
«Too damn well,» said Tommy briefly. «I’ve got to repair that solenoid. How about a job helping?»
The red-headed man unfastened the lugs of the rim, kicked the tire speculatively, and said, «Gone to hell.» He put on the spare tire with ease and dispatch.
«Um,» he said. «How about that Mr. Von Holtz? Is he goin’ to boss the job?»
«He is not,» said Tommy, with a shade of grimness in his tone.
The red-headed man nodded and took the soldering iron in hand. He unwound a strip of wire solder, mended the radiator tube with placid ease, and seemed to bang the cooling-flanges with a total lack of care. They went magically back into place, and it took close inspection to see that the radiator had been damaged.
«She’s all right,» he observed. He regarded Tommy impersonally. «Suppose you tell me how come you horn in on this,» he suggested, «an’ maybe I’ll play. That guy Von Holtz is a crook, if you ask me about him.»
Tommy ran his hand across his forehead, and told him.
«Um,» said the red-headed man calmly. «I think I’ll go break Mr. Von Holtz’s neck. I got me a hunch.»
He took two deliberate steps forward. But Tommy said, «I saw Denham not an hour ago. So far, he’s all right. How long he’ll be all right is a question. But I’m going after him.»
The red-headed man scrutinized him exhaustively.
«Um. I might try that myself. I kinda like the Professor. An’ Miss Evelyn. My name’s Smithers. Let’s go look through the dinkus the Professor made.»
They went together into the laboratory. Von Holtz was looking through the dimensoscope. He started back as they entered, and looked acutely uneasy when he saw the red-headed man.
«How do you do,» he said nervously. «They-the Ragged Men- have just brought in a dead man. But it is not the Herr Professor.»
Without a word, Tommy took the brass tube in his hand. Von Holtz moved away, biting his lips. Tommy stared into that strange other world.
The steel sphere lay as before, slightly askew upon a bank of glossy ferns. But its glass windows were shattered, and fragments of everything it had contained were scattered about. The Ragged Men had made a camp and built a fire. Some of them were roasting meat- the huge limb of a monstrous animal with a scaly, reptilian hide. Others were engaged in vehement argument over the body of one of their number, lying sprawled out upon the ground.
Tommy spoke without moving his eyes from the eyepiece. «I saw Denham with a club just now. This man was killed by a club.»
The Ragged Men in the other world debated acrimoniously. One of them pointed to the dead man’s belt, and spread out his hands. Something was missing from the body. Tommy saw, now, three or four other men with objects that looked rather like policemen’s truncheons, save that they were made of glittering metal. They were plainly weapons. Denham, then, was armed-if he could understand how the weapon was used.
The Ragged Men debated, and presently their dispute attracted the attention of a man with a huge black beard. He rose from where he sat gnawing at a piece of meat and moved grandly toward the disputatious group. They parted at his approach, but a single member continued the debate against even the bearded giant. The bearded one plucked the glittering truncheon from his belt. The disputatious one gasped in fear and flung himself desperately forward. But the bearded man kept the truncheon pointed steadily… The man who assailed him staggered, reached close enough to strike a single blow, and collapsed. The bearded man pointed the metal truncheon at him as he lay upon the ground. He heaved convulsively, and was still.
The bearded man went back to his seat and picked up the gnawed bit of meat again. The dispute had ceased. The chattering group of men dispersed.
Tommy was about to leave the eyepiece of the instrument when a movement nearby caught his eye. A head peered cautiously toward the encampment. A second rose beside it. Denham and his daughter Evelyn. They were apparently no more than thirty feet from the dimensoscope. Tommy could see them talking cautiously, saw Denham lift and examine a metal truncheon like the bearded man’s, and force his daughter to accept it. He clutched a club, himself, with a grim satisfaction.
Moments later they vanished quietly in the thick fern foliage, and though Tommy swung the dimensoscope around in every direction, he could see nothing of their retreat.
He rose from that instrument with something approaching hopefulness. He’d seen Evelyn very near and very closely. She did not look happy, but she did look alert rather than worn. And Denham was displaying a form of competence in the face of danger which was really more than would have been expected in a Ph.D., an M.A., and other academic distinctions running to most of the letters of the alphabet.
«I’ve just seen Denham and Evelyn again,» said Tommy crisply. «They’re safe so far. And I’ve seen one of the weapons of the Ragged Men in use. If we can get a couple of automatics and some cartridges to Denham, he’ll be safe until we can repair the big solenoid.»
«There was the small catapult,» said Von Holtz bitterly, «but it was dismantled. The Herr Professor saw me examining it, and he dismantled it. So that I did not learn how to calculate the way of changing the position-»
Tommy’s eyes rested queerly on Von Holtz for a moment. «You know how to make the metal required,» he said suddenly. «You’d better get busy making it. Plenty of it. We’ll need it.»
Von Holtz stared at him, his weak eyes almost frightened. «You know? You know how to combine the right angles?»
«I think so,» said Tommy. «I’ve got to find out if I’m right. Will you make the metal?»
Von Holtz bit at his too-red lips. «But Herr Reames!» he said stridently, «I wish to know the equation! Tell me the method of pointing a body in a fourth or a fifth direction. it is only fair-»
«Denham didn’t tell you,» said Tommy.
Von Holtz’s arms jerked wildly.
«But I will not make the metal! I insist upon being told the equation! I insist upon it! I will not make the metal if you do not tell me!»
Smithers was in the laboratory, of course. He had been surveying the big solenoid-catapult and scratching his chin reflectively. Now he turned.
But Tommy took Von Holtz by the shoulders. And Tommy’s hands were the firm and sinewy hands of a sportsman, if his brain did happen to be the brain of a scientist. Von Holtz writhed in his grip.
«There is only one substance which could be the metal I need, Von Holtz,» he said gently. «Only one substance is nearly threedimensional. Metallic ammonium! It’s known to exist, because it makes a mercury amalgam, but nobody has been able to isolate it because nobody has been able to give it a fourth dimension-duration in time. Denham did it. You can do it. And I need it, and you’d better set to work at the job. You’ll be very sorry if you don’t, Von Holtz!»
Smithers said with a vast calmness, «I got me a hunch. So if y’want his neck broke..
