Laser Watermarks

Chapter 35: Laser Watermarks The cart sluice was not built for people, and it punished everyone for using it. Lena crawled with Jun's white case grinding against her ribs, one hand locked around Elise's patched bulb, the other clamped over the evidence tube in her pocket. Black water slapped her chin whenever the tunnel dipped. Ahead, Sera dragged Elise through the narrow trough on her hip and counted breath with Micah's thin voice. "Fifteen," Micah whispered. Lena squeezed once. Behind them, recovery boots struck the nursery hatch hard enough to send grit down the sluice. A wash pump started with a hungry cough. The first clean sheet of tunnel rain swept over Lena's boots and turned the wet concrete dark. "They are washing it," Mara said from behind the stopper basin. "Not chasing first. Washing." "Then we read here." Lena planted her shoulder against the side wall and stopped. Arlo nearly hit her. He caught himself on the slimy brick, hands open, face half hidden by Rafi's quilt bundle. "If the pump pressure rises, this trough fills." "Tell me how long." He listened. The pipe above them knocked twice, paused, knocked fast. "Three minutes before the first flush reaches this bend. Less if Civic Rain overrides the old gate." "Mara?" Mara slid the covered stopper basin onto a raised brick lip and pulled the last wet seed from her sleeve. The seed was no larger than a pepper grain. She split it with a thumbnail. White smoke crawled out low, not enough to hide a person, just enough to touch water. The tunnel answered. Blue-green broken bars appeared on the falling rain, on the skin-safe film tube under Lena's fingers, on the black scuffs where Rafi's quilt had dragged, and on Sera's soaked sleeve where Elise's oxygen bag rubbed. The marks shivered in segments, bright only while smoke passed through them. Sera froze. "Do not film her arm." "I won't." Lena kept her camera high and angled at the wall. "Rafi, cloth between Elise and my lens. Micah, stay behind Sera's shoulder." The boy made himself smaller. "Sixteen." Lena squeezed the bulb and watched the nearest broken bars crawl over a stream of rainwater as if the water itself carried a hidden ticket. The pattern vanished where the water ran into clean shadow, then returned where smoke touched it. "Those are not child marks," Mara said. "They are on the film that touched water. Bag film, irrigation wrap, case sleeve, boot water." "VennDyne will say stolen property marked itself." "Seed inspectors use laser watermarks to prove licensed irrigation film was used on a paid plot." Mara bent close without touching the wall. "These have claim breaks. See? Three short, one long, two short. Not a farm license. Trial surface." Arlo looked toward the sound of the wash pump. "Insurance trials use surface claims. Rescue blankets. route mats, triage bags. If a body crosses a claimed surface, the insurer can count the rescue as a serviced event." Lena kept filming the wall, not faces. "Say that again without making yourself useful enough to lead." His jaw tightened. "My old evacuation packets had claim strips. I signed routes, not bodies. But if the route is marked after the fact, the score can pretend it served people it abandoned." The film in Lena's pocket felt colder. "So the unscored route can be washed, then billed as if they were never excluded." "Or owned as trial data," Mara said. "Adaptive rain touches them, then VennDyne says the rain learned rescue." The pump coughed again. A stronger runnel slid under Lena's knee and stripped smoke away from the floor. The blue-green bars blurred. Sera's voice sharpened. "Elise is slipping." Lena crawled forward, squeezed the bulb, and braced Elise's shoulder through the quilt without letting the camera drop. "Seventeen." Micah repeated it, steadier. From behind, a recovery voice entered the sluice through the open hatch, warped by pipe echo. "Illegal duplication team is in drainage branch. Flush tunnel. Preserve proprietary recovery surfaces." Rafi pressed the quilt tighter between the children and the wall marks. "They know about the marks." "They know what they need gone." Lena pulled Dr. Vale's skin-safe film from the evidence tube. The square had taken the case-sleeve bars in Chapter 034; now the marks glowed faintly on its surface whenever Mara's smoke licked it. The film curled at the wet edge, trying to fold in on itself. Mara hissed. "If that edge seals, the transfer smears." "How do I keep it open?" "Warm fingers, dry pressure, no sleeve water." Lena laughed once, ugly and breathless, because every part of her was soaked. She turned to Arlo. "Your glove. Palm out. No touching the mark." He stripped one glove and offered it across two inches of water. He waited until she nodded before he moved closer. Lena laid the unmarked edge over the dry inside of his glove and held the marked side to the smoky air. The blue-green segments sharpened. Not words. Not numbers. A route. The short and long bars formed a broken ladder around a faint circular stamp. Lena tilted the film toward the wet wall. The wall answered with the same ladder, except one rung was crossed out. Farther ahead, where the tunnel rain fell through a grate, another ladder glowed with the missing rung restored. "It's matching surfaces," Lena said. "Nursery, sluice, tunnel grate." Arlo's face changed. "What?" she asked. "That circle." He swallowed. "Old marshal evacuation sequence stamps used circles for approved direction. VennDyne should not have that grammar." "Could Civic Rain?" "Yes." The flush siren began as a low moan. Mara grabbed the stopper basin. "We move now or the evidence gets read by our lungs." Lena held the film to the smoke one second longer. The crossed-out rung brightened. Under it, a pale second pattern woke up, softer than the laser bars, like old ink seen through wet paper. Three characters appeared at the rim of the circle: E-seventeen. Then Pump Nine. Then a time sequence she had already seen too many times to mistake. Arlo's signed order route. But the bars did not sit under his sequence. They sat over it, cutting through the old direction stamp and rejoining it toward the adaptive-rain trial ladder ahead. Lena's mouth went dry. "Your order wasn't just backdated." Arlo stared at the film as if the tunnel had opened under him. "It was overwritten." The first flush hit the bend behind them. Water roared against the cart trough and lifted the quilt bundle. Rafi cursed and shoved his shoulder into it. Sera cried out as Elise's bag bobbed. "Move," Lena ordered. "Sera first. Micah count. Rafi, cloth high. Mara, smoke when I say. Arlo, carry the glove open." "The film is on my glove." "Then your hand is evidence. Do not be heroic with it." He nodded once. They crawled. The tunnel narrowed into a low service chamber with a rusted inspection grate overhead. Rain poured through it in silver ropes. Mara cracked the last half of the seed, and the chamber bloomed white. Every rope of rain lit blue-green. Above the grate, shadows moved. Not recovery boots. Dress shoes. Someone had walked to the public side of the service chamber and stopped exactly over the marked rain. A woman's voice came down through the grate, calm and amplified by the tunnel. "The recovery team has confirmed unauthorized removal from a claimed trial path." Celeste. Lena raised the camera only to the rain ropes and the glowing film on Arlo's open glove. "Then confirm this too," she said. She held the frame until the old order sequence appeared beneath the trial ladder, clear enough for any clerk with a memory and any sister with a grave to read. The final bar snapped into focus across Pump Nine and pointed forward, away from the nursery, toward a Civic Rain amendment mark. Celeste's shoes shifted above them. The wash pump slammed open. Water dropped through the grate in a hard white column. The film almost folded. Arlo cupped his hand without closing it. Lena slid the evidence tube beneath the marked edge, Mara threw the stopper cloth over the camera, and Sera screamed Elise's name as the bulb slipped from Lena's wrist. Micah's voice cut through the water. "Eighteen!" Lena caught the bulb by its patched neck, squeezed once, and saw the blue-green ladder on the film burn through the flood like a tiny, impossible map to Chapter Thirty-Six.
