short. A tall, impressive-looking Lhari strode through the crowd, followed at a respectful distance by two Mentorians, tall, redheaded humans wearing metallic cloaks like those of the Lhari. Tommy nudged Bart, his face bitter.
"Look at those lousy Mentorians! How can they do it? Fawning upon the Lhari that way, yet they're as human as we are! Slaves of the Lhari!"
Bart felt the involuntary surge of anger, instantly controlled. "It's not that way at all. My mother was a Mentorian, remember. She made five cruises on a Lhari ship before she married my father."
Tommy sighed. "I guess I'm just jealous — to think the Mentorians can sign on the Lhari ship as crew, while you and I will never pilot a ship between the stars. What did she do?"
"She was a mathematician. Before the Lhari met up with men, they used a system of mathematics as clumsy as the old Roman numerals. You have to admire them, when you realize that they learned stellar navigation with their old system, though most ships use human math now. And of course, you know their eyes aren't like ours. Among other things, they're color-blind. They see everything in shades of black or white or gray.
"So they found out that humans aboard their ships were useful. You remember how humans, in the early days in space, used certain birds, who were more sensitive to impure air than they were. When the birds keeled over, they could tell it was time for humans to start looking over the air systems! The Lhari use Mentorians to identify colors for them. And, since Mentor was the first planet of humans that the Lhari had contact with, they've always been closer to them."
Tommy looked after the two Mentorians enviously. "The fact is, I'd ship out with the Lhari myself if I could. Wouldn't you?"
Bart's mouth twisted in a wry smile. "No," he said. "I could — I'm half Mentorian, I can even speak Lhari."
"Why don't you? I would."
"Oh, no, you wouldn't," Bart said softly. "Not even very many Mentorians will. You see, the Lhari don't trust humans too much. In the early days, men were always planting spies on Lhari ships, to try and steal the secret of warp-drive. They never managed it, but nowadays the Lhari give all the Mentorians what amounts to a brainwashing — deep hypnosis, before and after every voyage, so that they can neither look for anything that might threaten the Lhari monopoly of space, nor reveal it — even under a truth drug — if they find it out.
"You have to be pretty fanatical about space travel to go through that. Oh, my mother could tell us a lot of things about her cruises with the Lhari. The Lhari can't tell a diamond from a ruby, except by spectrographic analysis, for instance. And she — "
A high gong note sounded somewhere, touching off an explosion of warning bells and buzzers all over the enormous building. Bart looked up.
"The ship must be coming in to land."
"I'd better check into the passenger side," Tommy said. He stuck out his hand. "Well, Bart, I guess this is where we say good-bye."
They shook hands, their eyes meeting for a moment in honest grief. In some indefinable way, this parting marked the end of their boyhood.
"Good luck, Tom. I'm going to miss you."
They wrung each other's hands again, hard. Then Tommy picked up his luggage and started down a sloping ramp toward an enclosure marked TO PASSENGER ENTRANCE.
Warning bells rang again. The glare intensified until the glow in the sky was unendurable, but Bart looked anyhow, making out the strange shape of the Lhari ship from the stars.
It was huge and strange, glowing with colors Bart had never seen before. It settled down slowly, softly: enormous, silent, vibrating, glowing; then swiftly faded to white-hot, gleaming blue, dulling down through the visible spectrum to red. At last it was just gleaming glassy Lhari-metal color again. High up in the ship's side a yawning gap slid open, extruding stairsteps, and men and Lhari began to descend.
Bart ran down a ramp and surged out on the field with the crowd. His eyes, alert for his father's tall figure, noted with surprise that the ship's stairs were guarded by four cloaked Lhari, each with a Mentorian interpreter. They were stopping each person who got off the starship, asking for identity papers. Bart realized he was seeing another segment of the same drama he had overheard discussed, and wished he knew what it was all about.
The crowd was thinning now. Robotcabs were swerving in, hovering above the ground to pick up passengers, then veering away. The gap in the starship's side was closing, and still Bart had not seen the tall, slim, flame-haired figure of his father. The port on the other side of the ship, he knew, was for loading passengers. Bart moved carefully through the thinning crowd, almost to the foot of the stairs. One of the Lhari checking papers stopped and fixed him with an inscrutable gray stare, but finally turned away again.
Bart began really to worry. Captain Steele would never miss his ship! But he saw only one disembarking passenger who had not yet been surrounded by a group of welcoming relatives, or summoned a robotcab and gone. The man was wearing Vegan clothes, but he wasn't Bart's father. He was a fat little man, with ruddy cheeks and a fringe of curling gray hair all around his bald dome. Maybe he'd know if there was another Vegan on the ship.
Then Bart realized that the little fat man was staring straight at him. He returned the man's smile, rather hesitantly; then blinked, for the fat man was coming straight toward him.
"Hello, Son," the fat man said loudly. Then, as two of the Lhari started toward him, the strange man did an incredible thing. He reached out his two hands and grabbed Bart.
"Well, boy, you've sure grown," he said, in a loud, cheerful voice, "but you're not too grown-up to give your old Dad a good hug, are you?" He pulled Bart roughly into his arms. Bart started to pull away and stammer that the fat man had made a mistake, but the pudgy hand gripped his wrist with unexpected strength.
"Bart, listen to me," the stranger whispered, in a harsh fast voice. "Go along with this or we're both dead. See those two Lhari watching us? Call me Dad, good and loud, if you want to live. Because, believe me, your life's in danger — right now!"
CHAPTER TWO
For a moment, pulled off balance in the fat stranger's hug, Bart remained perfectly still, while the man repeated in that loud, jovial voice, "How you've grown!" He let him go, stepping away a pace or two, and whispered urgently, "Say something. And take that stupid look off your face."
As he stepped back, Bart saw his eyes. In the chubby, good-natured red face, the stranger's eyes were half-mad with fear.
In a split second, Bart remembered the two Lhari and their talk of a fugitive. In that moment, Bart Steele grew up.
He stepped toward the man and took him quickly by the shoulders.
"Dad, you sure surprised me," he said, trying to keep his voice from shaking. "Been such a long time, I'd — half forgotten what you looked like. Have a good trip?"
"About like always." The fat man was breathing hard, but his voice sounded firm and cheerful. "Can't compare with a trip on the old Asterion though." The Asterion was the flagship of Vega Interplanet, Rupert Steele's own ship. "How's everything?"
Beads of sweat were standing out on the man's ruddy forehead, and his grip on Bart's wrist was so hard it hurt. Bart, grasping at random for something to say, gabbled, "Too bad you couldn't get to my graduation. I made th-third in a class of four hundred — "
The Lhari had surrounded them and were closing in.
The fat man took a deep breath or two, said, "Just a minute, Son," and turned around. "You want something?"
The tallest of the Lhari — the old one, whom Bart had seen on the escalator — looked long and hard at him. When they spoke Universal, their voices were sibilant, but not nearly so inhuman.
"Could we trrrouble you to sssshow us your paperrrssss?"
