Farradyne played with the high-space drive again, cutting some more didoes back and forth across space, ending up this time not too far from Mercury.

"Having fun?" asked Brenner.

"Shut up!" snapped Farradyne.

From below there came a rapid conversation in multitones, like someone dusting off the keys on a pipe organ played in mute.

Farradyne swore as he sat there looking at the big chronometer on the wall, counting off the seconds. Seventy of them went under the sweep hand before the radar trace hiked up into the same, familiar extreme-range warning.

Deliberately, Farradyne turned his ship toward Terra and hit the ultradrive. "They called me a hot-pants pilot," he gritted. "Now I'll really be one!"

Yellow-green Terra raced up and up and up through the spectrum and burst in size from an unwinking pin-point of light to a shockingly large disc that zoomed toward them frighteningly. They saw its roundness come out of the sky in a myriad colors until it filled the dome above them. Norma screamed, but by the time her voice had stopped echoing through the control room, Terra was past them by a good many miles of clean miss and Farradyne had cut the ultradrive. He grunted unhappily because he was now as far from Terra on the other side as he had been before he took the chance. This mad use of the enemy ultradrive in ducking around the solar system was something similar to trying to make a fifty-ton clam-shell digger split a cigarette paper; at two light years per hour, their speed was enough to take them from Sol to Pluto in one second flat. He could not control it finely enough to do more than zoom off out of sight. Without a doubt the big starship could maneuver at ultra-velocity with their drive cut in at microsecond intervals mechanico-electrically, of course, which was a setup that Farradyne did not have.

He shrugged, and then he patted Norma on the shoulder. "I don't think that my aim is good enough to hit the thing," he said. He turned the Lancaster end for end abruptly and tried a quick flick of the toggle. Once more Terra leaped at them, a swirling kaleidoscope of color, looming into monster size, flicking past.

When they came out of it Terra was again behind them by a few million miles. Farradyne thought for a moment, started to say, "Maybe we—" when he reached out and pressed the red button on the auxiliary panel, "—are being traced by the generator doodad they put below."

"But what are we going to do now?"
