The v-feed from Remote One showed a deep shadow cleft in the flank of the asteroid. The nearer edge, now drifting into view in a cone of brilliant white from the pod's lights, was razor sharp. The pool of illumination spread over the abrupt juncture, then vanished into a enormous cavity. Hadeishi could see the wall of the pit was glassy and smooth.
"Radiation readings are up, thermal signature is up. Exposed rock surfaces show the effects of extreme heat."
The chu-sa nodded to his exec. "The cutting beam mounted by a Tyr. Can you drag a time frame out of this data?"
"Processing now." Kosho's face had subtly changed and Hadeishi realized she was trying not to grin in triumph. "We'll know within ten minutes."
"Good." Hadeishi tapped a glyph to dispatch his reports and leaned forward in his seat. "During this time, have Remote One do a complete circuit of the pit and log the data for later analysis. Copy one set to legal and time-stamp and lock the archive." He fingered his beard idly, frowning in distaste at the thought. "I doubt the Tyr will allow itself to be brought in as a prize, but legal action may result. So – take care to make an authoritative record."
Kosho stared grimly at him for a long moment, puzzling Hadeishi. Then he remembered the events of the previous day and made an equivocal motion with one hand. Her expression did not change. "And plot us a course to the next 'disturbance'. Take us underway as soon as Remote One returns to the ship."
The sho-sa nodded and returned to her business, but Hadeishi could tell she was still displeased with him. She is young, he reminded himself, setting his memories of the incident aside again. She remembers too many things.
"Here is our present location," Kosho said, pointing out a blinking icon in the midst of the threat-well. A light green thread arced back from the winking mote to the orbit of the third planet. Hadeishi, Hayes and Smith stood around the railing. "The perturbation map we've built shows an irregular track through the main body of the belt in an anti-spinward direction."
A second thread appeared – this one a virulent red – entering the belt far behind their present location and spiraling forward through the diffuse mass. The red overran the green and continued for a good hand-span in the holodisplay. Kosho frowned at the indicator signaling the end of the track.
"We do not know how quickly the refinery ship is moving. In fact, as a Tyr can carry up to a dozen mining shuttles, this track may only be an aggregate path of the refinery and its satellite ships as they work through the field." Her hand brushed over the threat-well's control panel and the thread expanded into a heavy-bodied snake. "The possible locality of the refinery is somewhat larger."
Hadeishi looked to Hayes questioningly. "Can we cover a volume this large with our passive sensor envelope?"
The weapons officer shook his head dubiously. "Some of this volume will be scanned, but our usual range is degraded by all the debris. Hadeishi-san, we've picked up a lot of ambient radiation and particle decay in this area – definitely the exhaust of the big Royce-Energia XII sub-light engines mounted on a Tyr – so we can track them pretty closely if we follow right along their transit path, but -"
"We don't want to come at them so obviously," Hadeishi finished the sentence. "I do not intend to court danger, much less have my ship take a particle beam shot at close range, to catch these…these criminals. We will have to parallel their possible course from the edge of the volume, hoping to catch the refinery within our detection range." He paused, thinking.
"When I was growing up," Hadeishi continued in a musing tone, "the prefecture police often used smart-nosed dogs to hunt down thieves. What is the operational range of our ECM drones if we deploy them as sensor relays?"
Kosho and Hayes stared at him in surprise. "The outriders?"
"Yes," Hadeishi nodded, tapping up profiles of the devices in question. "These units are…yes, they are modular. We can program their sensor packs to search for this particle trail. Get with Isoroku and pull the chaff, jammer and spoofing racks from three of the drones and replace them with hydrogen cells to extend their time-on-station."
The weapons officer looked a little sick, but Kosho shook her head minutely and he subsided before openly questioning Hadeishi's command. "Sir -"
"I know." Hadeishi looked up from the panel. "We only have six drones and I'm asking you to cut the heart out of half our defensive network. However – with three drones reconfigured as sensor platforms we can rotate them on duty-station and extend our detection envelope across all, or nearly all, of your projected transit plot for the refinery. Our chances of being surprised by the Tyr will be greatly reduced." The captain tried a wintry smile, but neither the exec nor the weapons officer responded. "We have to be able to see them first or we've no chance of defeating this opponent."
Kosho looked like she'd bitten into a rotten quince, but nodded sharply. "Hai, Chu-sa. I will find engineer Yoyontzin and oversee the conversions myself."
Yoyontzin? Ah, I'd forgotten – Isoroku is still aboard the Palenque. Hadeishi considered changing the plan. But Kosho has an excellent eye for modifying equipment and we've some time, picking our way through this maze, before we come into range of the enemy.
"Very well, proceed. Keep me informed of your progress."
Both officers bowed and Hadeishi turned back to the plot, considering the difficulties of finding and subduing one ship – particularly one so well suited for this crowded, dangerous environment – in such an enormous volume. I have become a policeman, he thought, a little angry. So low has my house fallen… Then an amusing thought occurred. But this will be particularly bitter for our lady Kosho! A fine lot of keisatsu we are, chasing thieves in the night with our lanterns and rattan canes!
The Shuttle Wreck, Northern Hemisphere, Ephesus III
Despite lingering pain in her shins, Gretchen was suited up before sunrise. The nauallis was still a snoring lump in the tent, which let her range unmolested around the camp while he was safely asleep. With the sky still dark and her goggles dialed into ultraviolet, Anderssen felt a little queasy to see shoals of softly-glowing lights crowding around the edges of the tent. Close examination showed the tent to be free of infection, though the groundpad made from Hummingbird's shelter was rapidly disintegrating. Other scattered pools of radiance marked places where one of them had dropped a wrapper from a threesquare or bits of metal from the shuttle were still being digested. Despite walking in a long, wide circle around the camp, she did not find any tracks.
"Hmm," Gretchen muttered, pacing along the base of the nearest dune. She was surprised to see how quickly the wind wiped away the marks of human presence. Hummingbird's trail to the west had already been reduced to a shallow series of dimples, barely distinguishable from the ripples ascending the face of the ridge. "I must have been dreaming."
Anderssen was loath to put her gloves into the sand where she'd buried the sheet of hextiles, but the goggles didn't show her the usual glimmer under the sand. Gritting her teeth, Gretchen dug in and found the edge of the hexsheet. A moment later, the pad was uncovered and – remarkably, she thought – it was intact. So…Paxaxl Corporation Ceramobond doesn't taste good. That is excellent news.
