The sunblaze fooled him, dying slowly while it was still halfway to his horizon. He punched the time into his wristcomp, and realized that the builders of this zoo might be limited in the degree to which they could surrogate a planetary surface, when other vast circular cages were adjacent to this one. It was too much to ask that any zoo cage be, for its specimens, the best of all possible worlds.
Locklear slept badly, but he slept. During the times when he lay awake, he felt the silence like a hermetic seal around him, broken only by the rasp and slither of distant tree fronds in vagrant breezes. Kzin-normal microorganisms, the navigator had said; maybe, but Locklear had seen no sign of animal life. Almost, he would have preferred stealthy footfalls or screams of nocturnal prowlers.
The next morning he noted on his wristcomp when the ersatz kzinti sun began to blaze—not on the horizon, but seeming to kindle when halfway to its zenith—rigged a better sling for his right arm, then sat scratching in the dirt for a time. The night had lasted thirteen hours and forty-eight minutes. If succeeding nights were longer, he was in for a tooth-chattering winter. But first: find that damned transmitter.
Because it was small enough to fit in a pocket. And then—And then, he would not be held like a lap-dog on a leash. He pounded some kzin meat to soften it and took his first sightings while swilling from a water bulb.
The extension of that measured line, this time in the opposite direction, went more quickly except when he had to clamber on rocky inclines or cut one of those pulpy trees down to keep his sightings near perfect. He had no spirit level, but estimated the inclines as well as he could, as he had done before, and used the wristcomp’s trigonometric functions to adjust the numbers he took from his surveying thread. That damned kzin engineer was the kind who would be half-running to do his master’s bidding, and an eight-cubed of his paces might be anywhere from six hundred meters to a kilometer. Or the hidden transmitter might be almost underfoot at the cache; but no more than a klick at most. Locklear was pondering that when the zzrou zapped him again.
He stiffened, yelped, and whirled back several paces, then advanced very slowly until he felt its first half-hearted bite, and moved back, punching in the datum, working backward using the same system to make doubly sure of his numbers. At the cache, he found his two new numbers varied by five meters and split the difference. His southwest limit had been 437 meters away, his northeast limit 529; which meant the total length of that line was 966 meters. It probably wasn’t the full diameter of his circle, but those points lay on its circumference. He halved the number: 483. That number, minus the 437, was 46 meters. He measured off forty-six meters toward the northeast and piled pulpy branches in a pyramid higher than his head. This point, by God, was one point on the full diameter of that circle perpendicular to his first line! Next he had to survey a line at a right angle to the line he’d already surveyed, a line passing through that pyramid of branches.
It took him all morning and then some, lengthening his thread to be more certain of that crucial right-angle before he set off into the jungle, and he measured almost seven hundred meters before that bloody damned zzrou bit him again, this time not so painfully because by that time he was moving very slowly. He returned to the pyramid of branches and struck off in the opposite direction, just to be sure of the numbers he scratched in the dirt using the wristcomp. He was filled with joy when the zzrou faithfully poisoned him a bit over 300 meters away, within ten meters of his expectation.
Those first three limit points had been enough to rough out the circle; the fourth was confirmation. Locklear knew that he had passed the transmitter on that long northwest leg; calculated quickly, because he knew the exact length of that diameter, that it was a bit over two hundred meters from his pyramid; and measured off the distance after lunch.
“I just like that fur-licking bastard,” he said, looking around him at the tangle of orange, green, and yellow jungle growth. “Probably shit on it before he buried it.”
Locklear spent a fruitless hour clearing punky shrubs and man-high ferns from the soft turf before he saw it, and of course it was not where he had been looking at all. “It” was not a telltale mound of dirt, nor a kzin footprint. It was a group of three globes of milky sap, no larger than water droplets, just about knee-high on the biggest palm in the clearing. And just about the right pattern for a kzin’s toe-claws.
He moved around the trunk, as thick as his body, staring up the tree, now picking out other sets of milky puncture marks spaced up the trunk. More kzin clawmarks. Softly, feeling the gooseflesh move down his arms, he called, “Ollee-ollee-all’s-in-free”, just for the hell of it. And then he cut the damned tree down, carefully, letting the breeze do part of the work so that the tree sagged, buckled, and came down at a leisurely pace.
The transmitter, which looked rather like a wristcomp without a bracelet, lay in a hole scooped out by Yellowbelly’s claws in the tender young top of the tree. It was sticky with sap, and Locklear hoped it had stung the kzin as it was stinging his own fingers. He wiped it off with vine leaves, rinsed it with dribbles of water from severed vines, wiped it off again, and then returned to his food cache.
“Yep, the shoulder hurts, and the damned gravity doesn’t help but,” he said, and yelled it at the sky, “now I’m loose, you rat-tailed sons of bitches!”
He spent another night at the first cache, now with little concern about things that went bump in the ersatz night. The sunblaze dimmed thirteen hours and forty-eight minutes after it began, and Locklear guessed that the days and nights of this synthetic arena never changed. “It’d be tough to develop a cosmology here,” he said aloud, shivering because his right shoulder simply would not let him generate a fire by friction. “Maybe that was deliberate.” If he wanted to study the behavior of intelligent species without risking their learning too much, and had not the faintest kind of ethics about it, Locklear decided he might imagine just such a vast enclosure for the kzinti. Only they were already a spacefaring race, and so was humankind, and he could have sworn the adjacent area on this impossible zoo planet was a ringer for one of the wild areas back on Earth. He cudgeled his memory until he recalled the lozenge shape of that lake seen from orbit, and the earthlike area.
“Right-about-there,” he said, nodding to the southwest, across the lake. “If I don’t starve first.”
He knew that any kzinti searching for him could simply home in on the transmitter. Or maybe not so simply, if the signal was blocked by stone or dirt. A cave with a kink in it could complicate their search nicely. He could test the idea—at the risk of absorbing one zap too many from that infuriating zzrou clinging to his back.
“Well, second things second,” he said. He’d attended to the first things first. He slept poorly again, but the collarbone seemed to be mending. Locklear admitted an instant’s panic the next morning (he had counted down to the moment when the ersatz sun began to shine, missing it by a few seconds) as he moved beyond his old limit toward the lake. But the zzrou might have been a hockey puck for its inertness. The lake had small regular wavelets easy enough to generate if you have a timer on your gravity polarizer, he mused to the builders—and a narrow beach that alternated between sand and pebbles. No prints of any kind, not even birds or mollusks. If this huge arena did not have extremes of weather, a single footprint on that sand might last a geologic era.
