He peered through the gyro's side glass searching for the white peak of Green Mountain to check his position. The skyglow of Denver shimmered in the east, but the peak was lost in darkness.

"You misunderstand our motive," the alien said. "But you're quite right about our base on Pluto. Induction again?"

"On a different level, yes," Manson said. "Pluto is a solar anomaly—a small, heavy planet where there should be nothing but a larger and lighter world. Pluto was never born to Sol—it's an alien planet, brought in from Outside by you Watchers."

A red light winked on the control panel, and the gyro swerved fractionally. A fiery streak of crimson rocket exhaust flared ahead and vanished, explaining the deviation.

"Seattle-Miami express," Manson muttered. Then the unnatural angle of the exhaust-trail registered, troubling him. "But it shouldn't cross my course—and it should be going up, not down!"

"Your crusade is based on a false premise," Havlik said. "We came to Earth less than fifty years ago, not to destroy humanity but to guide it. The Kha Niish sent us as missionaries, to sow the seed of Their benign culture among men as we have sowed it among a thousand other infant races born into Their galaxy."

The gyro tilted, spiraling down for a landing. A farmhouse, lighted windows cheerful against the dark countryside, rose to meet it. Beside the house, standing on end like a giant cartridge case, Manson saw a sleek, shining bulk—a ship.

He raised incredulous eyes to meet the alien's dark stare. Comprehension stunned him.

"You fiend," he breathed. "You've tricked me somehow—you've played cat-and-mouse with me from the first!"
