A giant cylindrical hull of finest beryl steel, the ship loomed in the screen. A mighty ship, braced into absolute rigidity by monster cross beams of shining steel. Glowing under the blazing lamps that lighted the scene, it towered into the shadows of the factory, dwarfing the scurrying workmen who swarmed over it.

"She's a beauty," said Russ, puffing at his pipe.

Greg nodded agreement. "They're working on her day and night to get her finished. We may need it some day and need it in a hurry. If Chambers really gets that machine of his to rolling, space will be the only place big enough to hide in."

He chuckled, a grim chuckle, deep in his throat.

"But we won't have to hide long. Just until we get organized and then will come the time when we'll call for the showdown. Chambers will have to spread his cards."

Russ snapped the television switch and the screen went blank. The laboratory suddenly was a place of queer lights and shadows, bulging with grotesque machines, with sprawling apparatus, a place that hinted darkly of vast power and mighty forces.

The scientist sat up in his chair. "We've come a long way, Greg. A long, long way. We have the greatest power man has ever known; we have an almost incomprehensible space drive; we have three-dimensional television."

"And," said Greg dryly, "we took Chambers to the cleaners on the market."

They sat in silence. Greg smelled the smoke from Russ's pipe, mixed with the taint of lubricant and the faint lingering scent of ionized air.

"We mustn't underrate Chambers, however," he declared. "The man made one mistake. He underrated us. We can't repeat his mistake. He is dangerous all the time. He will stop at nothing. Not even murder."
