.
But the similarity ended there.
They had skin of a curious pale silvery gray, and pale, pure-white hair rising in what looked like a feathery crest. The eyes were long and slanting, the forehead high and narrow, the nose delicately thin and chiseled with long vertically slit nostrils, the ears long, pointed and lobeless. The mouth looked almost human, though the chin was abnormally pointed. The hands would almost have passed inspection as human hands — except for the long, triangular nails curved over the fingertips like the claws of a cat. They wore skin-tight clothes of some metallic silky stuff, and long flowing gleaming silvery capes. They looked unearthly, elfin and strange, and in their own way they were beautiful.
The two Lhari in front of Bart had been talking softly, in their fast twittering speech; but as the hum of the crowds on the upper levels grew louder, they raised their voices, and Bart could hear what they were saying. He was a little surprised to find that he could still understand the Lhari language. He hadn't heard a word of it in years — not since his Mentorian mother died. The Lhari would never guess that he could understand their speech. Not one human in a million could speak or understand a dozen words of Lhari, except the Mentorians.
"Do you really think that human — " the first Lhari spoke the word as if it were a filthy insult — "will have the temerity to come in by this ship?"
"No reasonable being can tell what humans will do," said the second Lhari. "But then, no reasonable being can tell what our own Port Authorities will do either! If the message had only reached us sooner, it would have been easier. Now I suppose it will have to clear through a dozen officials and a dozen different kinds of formalities."
The younger Lhari sounded angry. "And we have only a description — no name, nothing! How do they expect us to do anything under those conditions? What I can't understand is how it ever happened, or how the man managed to get away. What worries me is the possibility that he may have communicated with others we don't know about. Those bungling fools who let the first man get away can't even be sure — "
"Do not speak of it here," said the old Lhari sharply. "There are Mentorians in the crowd who might understand us." He turned and looked straight at Bart, and Bart felt as if the slanted strange eyes were looking right through to his bones. The Lhari said, in Universal, "Who are you, boy? What iss your businesssses here?"
Bart replied in the same language, politely, "My father's coming in on this ship. I'm looking for the information desk."
"Up there," said the old Lhari, pointing with a clawed hand, and lost interest in Bart. He said to his companion, in their own language, "Always, I regret these episodes. I have no malice against humans. I suppose even this Vegan that we are seeking has young, and a mate, who will regret his loss."
"Then he should not have pried into Lhari matters," said the younger Lhari fiercely. "If they'd killed him right away — "
The soaring staircase swooped up to the top level; the two Lhari stepped off and mingled swiftly with the crowd, being lost to sight. Bart whistled in dismay as he got off and turned toward the information desk. A Vegan! Some poor guy from his own planet was in trouble with the Lhari. He felt a cold, crawling chill down his insides. The Lhari had spoken regretfully, but the way they'd speak of a fly they couldn't manage to swat fast enough. Sooner or later you had to get down to it, they just weren't human!
Here on Earth, nothing much could happen, of course. They wouldn't let the Lhari hurt anyone — then Bart remembered his course in Universal Law. The Lhari spaceport in every system, by treaty, was Lhari territory. Once you walked beneath the lightning-flash sign, the authority of the planet ceased to function; you might as well be on that unbelievably remote world in another galaxy that was the Lhari home planet — that world no human had ever seen. On a Lhari spaceport, or on a Lhari ship, you were under the jurisdiction of Lhari law.
Tommy stepped off a moving stair and joined him. "The ship's on time — it reported past Luna City a few minutes ago. I'm thirsty — how about a drink?"
There was a refreshment stand on this level; they debated briefly between orange juice and a drink with a Lhari name that meant simply cold sweet, and finally decided to try it. The name proved descriptive; it was very cold, very sweet and indescribably delicious.
"Does this come from the Lhari world, I wonder?"
"I imagine it's synthetic," Bart said.
"I suppose it won't hurt us?"
Bart laughed. "They wouldn't serve it to us if it would. No, men and Lhari are alike in a lot of ways. They breathe the same air. Eat about the same food." Their bodies were adjusted to about the same gravity. They had the same body chemistry — in fact, you couldn't tell Lhari blood from human, even under a microscope. And in the terrible Orion Spaceport wreck sixty years ago, doctors had found that blood plasma from humans could be used for wounded Lhari, and vice versa, though it wasn't safe to transfuse whole blood. But then, even among humans there were five blood types.
And yet, for all their likeness, they were different.
Bart sipped the cold Lhari drink, seeing himself in the mirror behind the refreshment stand; a tall teen-ager, looking older than his seventeen years. He was lithe and well muscled from five years of sports and acrobatics at the Space Academy, he had curling red hair and gray eyes, and he was almost as tall as a Lhari.
Will Dad know me? I was just a little kid when he left me here, and now I'm grown-up.
Tommy grinned at him in the mirror. "What are you going to do, now we've finished our so-called education?"
"What do you think? Go back to Vega with Dad, by Lhari ship, and help him run Vega Interplanet. Why else would I bother with all that astrogation and math?"
"You're the lucky one, with your father owning a dozen ships! He must be almost as rich as the Lhari."
Bart shook his head. "It's not that easy. Space travel inside a system these days is small stuff; all the real travel and shipping goes to the Lhari ships."
It was a sore point with everyone. Thousands of years ago, men had spread out from Earth — first to the planets, then to the nearer stars, crawling in ships that could travel no faster than the speed of light. They had even believed that was an absolute limit — that nothing in the universe could exceed the speed of light. It took years to go from Earth to the nearest star.
But they'd done it. From the nearer stars, they had sent out colonizing ships all through the galaxy. Some vanished and were never heard from again, but some made it, and in a few centuries man had spread all over hundreds of star-systems.
And then man met the people of the Lhari.
It was a big universe, with measureless millions of stars, and plenty of room for more than two intelligent civilizations. It wasn't surprising that the Lhari, who had only been traveling space for a couple of thousand years themselves, had never come across humans before. But they had been delighted to meet another intelligent race — and it was extremely profitable.
Because men were still held, mostly, to the planets of their own star-systems. Ships traveling between the stars by light-drive were rare and ruinously expensive. But the Lhari had the warp-drive, and almost overnight the whole picture changed. By warp-drive, hundreds of times faster than light at peak, the years-long trip between Vega and Earth, for instance, was reduced to about three months, at a price anyone could pay. Mankind could trade and travel all over their galaxy, but they did it on Lhari ships. The Lhari had an absolute, unbreakable monopoly on star travel.
"That's what hurts," Tommy said. "It wouldn't do us any good to have the star-drive. Humans can't stand faster-than-light travel, except in cold-sleep."
Bart nodded. The Lhari ships traveled at normal speeds, like the regular planetary ships, inside each star-system. Then, at the borders of the vast gulf of emptiness between stars, they went into warp-drive; but first, every human on board was given the cold-sleep treatment that placed them in suspended animation, allowing their bodies to endure the warp-drive.
He finished his drink. The increasing bustle in the crowds below them told him
