Von Holtz bowed stiffly and went out of the laboratory. Tommy looked after him. Even moved to make sure he was gone. And then Tommy Reames went quickly to the work bench on which were the littered notes and calculations Von Holtz had been using and which were now at his disposal. But Tommy did not leaf through them. He reached under the blotter beneath the whole pile. He had seen Von Holtz furtively push something out of sight, and he had disliked and distrusted Von Holtz from the beginning. Moreover, it was pretty thoroughly clear that Denham had not trusted him too much. A trusted assistant should be able to understand, at least, any experiment performed in a laboratory. A folded sheet of paper came out. Tommy glanced at it. "You messed things up right! Denham marooned and you got nothing. No plans or figures either. When you get them, you get your money. If you don't you are out of luck. If this Reames guy can't fix up what you want it'll be just too bad for you." There was no salutation nor any signature beyond a scrawled and sprawling "J." Tommy Reames' jaw set grimly. He folded the scrap of paper and thrust it back out of sight again. "Pretty!" he said harshly. "So a gentleman named 'J' is going to pay Von Holtz for plans or calculations it is hoped I'll provide! Which suggests--many things! But at least I'll have Von Holtz's help until he thinks my plans or calculations are complete. So that's all right...." Tommy could not be expected, of course, to guess that the note he had read was quite astounding proof of the interest taken in non-Euclidean geometry by a vice king of Chicago, or that the ranking beer baron of that metropolis was the man who was so absorbed in abstruse theoretic physics. * * * * * Tommy moved toward the great solenoid which lay askew upon its wrecked support. It had drawn the steel globe toward it, had made that globe vibrate madly, twice, and then go hazy and vanish. It had jerked the globe in each of five directions, each at right angles to all the others, and had released it when started in the fifth dimension. The huge coil was quite nine feet across and would take the steel globe easily. It was pivoted in concentric rings which made up a set of gymbals far more elaborate than were ever used to suspend a mariner's compass aboard ship. There were three rings, one inside the other. And two rings will take care of any motion in three dimensions. These rings were pivoted, too, so that an unbelievably intricate series of motions could be given to the solenoid within them all. But the device was broken, now. A pivot had given away, and shaft and socket alike had vanished. Tommy became absorbed. Some oddity bothered him....
