The cab swooped down. Bart found his voice. "But what then? Is Dad there? Will I know—"

"I don't know any more than I've told you," Briscoe said. Abruptly the robotcab came to a halt, swaying a little. Briscoe jerked the door open, gave Bart a push, and Bart found himself stumbling out on the ramp beside the spaceport building. He caught his balance, looked around, and realized that the robotcab was already climbing the sky again.

Immediately before him, neon letters spelledTO PASSENGER ENTRANCE ONLY. Bart stumbled forward. The Lhari by the gate thrust out a disinterested claw. Bart held up what Briscoe had shoved into his hand, only now seeing that it was a thin wallet, a set of identity papers and a strip of pink tickets.

"Procyon Alpha. Corridor B, straight through." The Lhari gestured, and Bart went through the narrow passageway, came out at the other end, and found himself at the very base of a curving stair that led up and up toward a door in the side of the huge Lhari ship. Bart hesitated. In another minute he'd be on his way to a strange sun and a strange world, on what might well be the wild-goose chase of all time.
