That rule had been adopted over a thousand years before, after a disastrous clutch of mistakes had devastated the ecology of the colony world of Elysian, and no administration on a planet in the early stages of settlement would even consider its violation without a reason far more compelling than the minuscule economic loss thefts of celery represented. But that hadn't ruled out trip wires, photoelectric detectors, and pressure plates. They were attached to lights or alarms or passive camera systems, but somehow the celery thieves always seemed to avoid them. There had been that one time when someone — or, Stephanie thought deliciously, something — had tripped a camera over in Jefferies Land in the middle of a howling blizzard. Unfortunately, all the exterior camera had recorded was a lot of swirling snow.
Given how hard others had been working on the mystery, Stephanie was willing to admit that it was unlikely she would be the one to solve it. But that wasn't the same as impossible, and she'd been very careful to leave the ventilation louvers open on the greenhouse which contained her mother's celery. The odds were against anything coming along to take advantage of the opportunity, but it wasn't as if Stephanie had a lot of other things to do just now, and she settled back in her chair, camera in her lap, as the first spatters of rain began to fall.
Climbs Quickly paused, head and shoulders rising as he stood high on his true-feet and hand-feet like — had he known (or cared) — an Old Terran prairie dog to peer into the night. This was the closest he'd ever come to his two-legs' living place, and his eyes glowed as he realized he'd been right. He had been tasting a mind glow from them, and he stood motionless in the darkness as he savored the texture.
It was unlike anything he'd ever tasted from another of the People… and yet it wasn't unlike. It was… was…
He sat down, curling his tail about his toes, and rubbed one ear with a true-hand while he tried to put a label on it. It was like the People, he decided after long, hard moments of thought, but without words. It was only the emotions, the feelings of the two-legs, without the shaping that turned those into communication, and there was a strange drowsiness to it, as if it were half-asleep. As if, he thought slowly, the mind glow rose from minds which had never even considered that anyone else might be able to taste or hear them and so had never learned to use it to communicate. Yet even as he thought that, it seemed impossible, for the glow was too strong, too powerful. Unformed, unshaped, it blazed like some marvelous flower, brighter and taller than any of the People had ever produced in Climbs Quickly's presence, and he shivered as he wondered what it would have been like if the two-legs hadn't been mind-blind. He felt the brightness calling to him, tempting him closer like a memory singer's song, and he shook himself. This would be a very important part of his next report to Sings Truly and Short Tail, but he certainly had no business exploring it on his own before he reported it. Besides, it wasn't what he'd come for.
He shook himself again, stepping back from the mind glow, but it was hard to distance himself from it. In fact, he had to make a deliberate, conscious decision not to taste it and then close his mind to it, and that took much longer to manage than he'd expected.
Yet he did manage it, eventually, and drew a deep breath of relief as he pulled free. He flipped his ears, twitched his whiskers, and began sliding once more through the darkness as the first raindrops splashed about him.
The rain came down harder, drumming on the gazebo roof. The air seemed to dance and shiver as incessant lightning split the night and thunder shook its halves, and Stephanie's eyes glowed as wind whipped spray in through the gazebo's open sides to spatter the floor and kiss her eyelashes and chilled cheeks. She felt the storm crackling about her and hugged it to herself, drinking in its energy.
But then, suddenly, a tiny light began to flash on her camera, and she froze. It couldn't be! But the light was flashing — it really was! — and that could only mean—
She pressed the button that killed the warning light, then snatched the camera up to peer through the viewfinder. Visibility was poor through the rain cascading off the gazebo roof. There was too much water in the air for a clear view, even with the camera's light-gathering technology, and the lightning didn't help as much as one might have expected. The camera adjusted to changing light levels more quickly than any human eye, but the contrast between the lightning's split-second, stroboscopic fury and the darkness that followed was too extreme.
Stephanie knew that, and she hadn't really expected to see anything just yet, anyway. Since the celery bandits had proved so clever at avoiding mechanical devices like trip wires, most of those working on the problem had opted for more subtle approaches. Photoelectric beams had been the next obvious approach, but whoever it was actually seemed to avoid them even more readily than he — or they — avoided mechanical barriers.
But Stephanie had a theory about why that was. In every case she'd been able to research, the photoelectric system used had employed infrared. Well, obviously visible light wouldn't work for something like that, and people had used infrared for such systems just about forever. But Stephanie's discussions with her father about his work with the fledgling Sphinx Forestry Service had led her to suspect that the people setting up those systems here had failed to adequately analyze their problem. From what Daddy said, relatively new evidence suggested that Sphinx wildlife used much more of the lower end of the spectrum than human eyes. That meant a Sphinxian animal might actually see the infrared light a human couldn't, and that, in turn, would make the photoelectric beams relatively easy to avoid, so Stephanie's alarms used the other end of the spectrum.
It hadn't been hard for her and Daddy to tinker them up in his workshop, and he'd helped her weave a solid wall of ultraviolet beams to cover the opened louvers. But while he and Mom knew all about her sensors, they thought she'd connected them to the data terminal in her room. Which she had. She just hadn't mentioned that for tonight she'd disabled the audible alarm on her data terminal and set up a silent relay to her camera, instead. Mom and Daddy were smart enough to guess why she might have done that, but since they hadn't specifically asked, she hadn't had to tell them, and that meant they hadn't gotten around to forbidding her to lurk in the gazebo tonight, which was certainly the most satisfactory outcome for all concerned.
If pressed, Stephanie would have conceded that her parents might have quibbled with that last conclusion, but what mattered at this particular moment was that something had just climbed through the open louver. Whatever was stealing celery was inside the greenhouse right this minute, and she had a chance to be the very first person on Sphinx to get actual pictures of it!
She stood for a moment, biting her lip and wishing she had better visibility, then shrugged. Mom and Dad wouldn't be a lot madder at her for getting soaked than they'd be over her having snuck out at all, and she needed to get closer to the greenhouse. She took a second to clip the rain shield onto the camera, then dragged her hat down over her ears, drew a deep breath, and splashed down the gazebo steps into the rain-whipped night.
Climbs Quickly found it even harder to ignore the two-leg mind glows as he dropped to the soft, bare earth of the plant place's floor. The rich smells of unknown growing things filled his nostrils, and his tail twitched as he absorbed them. The transparent material of the plant place seemed far too thin to resist the rain beating upon it, yet it did, and without a single drop leaking through! The two-legs were truly clever to design a marvel like that, and he sat for a moment luxuriating in the enfolding warmth that was made somehow even warmer and more welcoming by the furious splashing of the icy, lightning-laced rain.
