They entered the ship’s tiny circular gym from opposite sides. Sparta was slight, muscular, her sandy blond hair falling straight to her jawbone, where it was chopped off in a practical cut that made no concession to fashion; the bangs above her thick brows were short enough to leave her dark blue eyes unscreened. Blake was a few centimeters taller, with broader shoulders and heavier muscles. His dark auburn hair was as straight and choppy as hers and his green eyes were as steady as hers; his ChineseIrish face could have been unsettlingly pretty, but it was saved from perfection by a too-wide mouth and a sprinkle of freckles across his straight nose.
They bowed to each other, then straightened. A heart’s beat . . . their knees flexed, their hands came up like blades, they began warily to close. Unlike most human fighters, who tend to circle, they came straight on like animals. In combat, neither favored their right or left; any such asymmetries they had failed to train out of themselves would be betrayed only in the extremity.
At two meters distance they reached an imaginary boundary, the edge of the lethal zone. Here each could still take in the other at a glance, from head to foot, from eye to hand. Here neither could reach the other without evident preparation.
But Blake was the one with something to prove; he would have to make the first move. It was quick, a leap and a high wide-legged kick that left him vulnerable. For a flicker of time her inhibition intervened– as he had calculated and hoped.
She would not be reticent again. So quickly was she on him when he landed that he barely escaped with a sideways roll. He regained his balance and shot a hard jab at her belly, but she pivoted and chopped at his neck, connecting only with air.
A shoulder roll across the rough polycanvas floor of the gym brought Sparta bounding to her feet in time to catch Blake’s counterattack; despite a feint to her midriff with his left fist she easily read his intention and brushed aside his right hand as it swung toward her nose, taking his wrist. As she pivoted to take his arm down and past, she indulged in a split-second’s reconsideration and realized that the move had been a setup. Here was the real assault. Just as the fingers of his left hand brushed the lapel of her gi, she let go and somersaulted backward, launching herself with a knee to his hip; his fingers closed on nothing.
Again they rolled away to opposite sides of the little gym. Again they bounced up, panting. Both were pouring sweat, nearing exhaustion. For ten minutes they’d been going at each other with all the strength and guile they could muster. He’d laid an offensive hand on her just once. She’d done little better. The ruddy patch on her cheekbone where he’d caught her with the hard edge of his palm was darkening to a bruise; his bruises, on his ribs and the outside of his left thigh, were invisible under his gi, but they would leave him limping when he cooled down.
In half a second he had hitched up his thick black belt and freed it from where it was strapped to the small of his back. Its diamond-filmed carbon-carbon blade was just long enough to be lethal; standard North Continental Treaty Alliance military issue, it was a useful tool for cutting or stabbing or, in a pinch, for throwing.
Warily he circled, lunged in a feint, recovered before her darting hand could capture his wrist, lunged again and went inside her guard, found himself snared by her leg and had to snap roll out of it, found her diving for him. He faked a retreat and then rolled into her; she overshot.
Before he could get to his knees she was back on her feet and coming at him. He measured the kick aimed at his head and dodged it, but her bare heel connected with his wrist instead. The knife flew out of his numbed fingers, but he got his other hand on the back of her black belt and allowed her momentum to carry him onto her back as she sprawled. His right hand was useless, but his arm went around her neck and he pulled her chin back with the crook of his elbow.
Not soon enough. One of her legs and one of her arms had escaped his pin and she was twisted sideways under him. He felt the tip of his own knife against his kidney; her long jump had brought it into her hand.
“You don’t think so?” She put her hands behind her neck and gripped it with knitted fingers, rolling her head to stretch out the kinks. “What if Khalid turns out to be our man after all? You said his training was the same as yours.”
Sparta said nothing. He had no idea how easy it would be for her to find him, no matter how cleverly he disguised himself, no matter what steps he took to cover his trail. She could follow the touch and smell of him, the warm tracks of him, anywhere he tried to run. That he had fought her to a draw impressed her, for she had fought as hard as was humanly possible. But she did not want him to know how far she was from simply human, or that she had not used against him the abilities that set her apart.
Not that she was stronger or better coordinated than he. Her muscles were smaller and her ordinary nerve impulses were no quicker than his, but this was compensated in the normal way of things by her smaller size and mass, her ability to move the parts of her body faster through space in simple obedience to the laws of physics. Weightlifters are not good gymnasts; sumo wrestlers are not good at karate. But between her and him it was an even match, more even than it might have been.
Things had been done to her brain, among other organs. The natural human brain had evolved to its species-specific state in grasslands and open forests. The ancestors of humans effortlessly performed simultaneous partial differential equations, continually matching and revising trajectories while running alongside fleeing zebras and wildebeests while pelting them with rocks, or swinging from branch to branch, plucking an occasional fruit along the way–and our relatives can still be observed doing it, in the great parks of Africa and the Amazon. We humans retain some of this ability, if only a shadow.
We are very good at throwing things, much better than our nearest relatives, the chimpanzees–good at hurling spears, shooting arrows, aiming guns, playing horseshoes, and so forth. We are almost as good at catching things. Perhaps the most extraordinary demonstration of the human brain’s capacity to compute and match trajectories occurred in the mid-20th century when an athlete named Mays, playing the traditional American game called baseball, positioned himself–while running as fast as he could–beneath a small white horsehide-covered sphere which, struck by an ashwood club, had been lofted into the air some hundreds of feet on an unpredictable parabola. Mays–still running, not turning around, and shortly before colliding with a wall marking the boundary of the playing field–caught the ball as it descended over his left shoulder into his glove.
Probably no natural human before Mays or since could have done that. But Sparta, if the need arose, could do the equivalent. The tiny dense knot of cells that nestled in her forebrain just a little to the side of where the Hindus place the eye of the soul was a processor that integrated trajectories and made many other kinds of calculations faster, far faster, than the brain itself. Had she made use of this knot of cells, had she switched it into her mental circuits, Sparta could have read every move Blake Redfield made before he had well started it; she could have ground his face into the mat ten seconds after their match had begun.
“Okay,” she said. “You can work on your own. If you promise to keep in touch.” She didn’t tell him he was right, that he was probably as formidable as anything the enemy could bring against him. And if they were armed, which was likely–well, he would be too.
He leaned toward her, and as his lips parted there was a softness about his eyes and mouth, an expression almost of longing. But then a ripple of uncertainty crossed his face. His mask hardened. When he spoke he said, “I wish I could say the same.”
“Because that’s why I’m here. . . .” He broke off. When his emotions got the better of him he sometimes forgot that he must always call her Ellen, if he named her at all. When he’d first met her as a child, and throughout the eight years of their growing up together, her name had been Linda. “That’s what all this is about.”
She was saved a reply when the elevator door abruptly slid open. “Let’s talk to the captain.” “Through the flush tubes,” said the captain. Her name was Walsh, and she was maybe thirty years old, this veteran cutter pilot–old enough to have gained the experience, young enough to have retained the synapses. “We put you in a bolus bag, flush you into the station’s holding tank; half an hour or so later, somebody fishes you out.”
Walsh shook her close-cropped head. “We know there’ll be spies. Every port crawls with ’em, freelance types mostly. We know some of the spies on Mars Station, and we know they’re onto what you call the traditional methods, Inspector–assuming you mean laundry bags, that kind of stuff.” She shrugged. “Told me before, we could have dumped him on Phobos, picked him off on the next orbit.”
Mars Station dominated the sky, its thick blunt cylinder turning against the stars, its axis pointing straight down; from the approaching cutter’s angle the space station looked like a slowly spinning top, balanced on the sharp arc of the planet’s horizon.
Newer and more comfortable than L-5, the first of the giant space settlements which orbited the Earth, but older and simpler than Venus’s Port Hesperus, the crown jewel of colonies, Mars Station was a pragmatic place built from metal and glass that had been smelted from a captured asteroid, its design owing much to the Soviet engineers who had supervised its construction. The station was too close in the cutter’s videoplates for those on board to see anything but the glassy expanse of the cylinder’s starside end–its angled mirrors, its communications masts, its docking bays protruding from the unrotating axle like spokes from a nave.
