After the container had settled onto the deck cradle with that dull thud, none of them celebrated, and none of them gave it a second admiring look. A gust off the sea scattered excitement quickly; what remained was only don’t let anything go wrong.

  Anika was first to act. She rammed the temporary plugs tight into the scuppers, then pressed absorbent pads down over the black streaks under the container. “This isn’t mystery. It’s seabed rot and old oil. Let it get into the pipework and we’ll buy ourselves a second job the moment we get back.”

  Raphael crouched to look at the stain and pulled a face. “Money smells lovely. This doesn’t.”

  Keiko didn’t look up; her finger moved quickly over the tablet. “Secure it first. The checklist isn’t finished. Seals intact. Photos complete.”

  Saitō shut the lid fully and ran another band of sealing tape around the outer layer, pressing the edges down hard. “We don’t open it again. Back in port.”

  “In port we may not open it at all,” Anika added. “In port it’s ordinary old-world salvage. If we have to look stupid, we look stupid.”

  Raphael glanced up. “Looking stupid is one of my more refined skills.”

  Keiko gave him a flat look. “Don’t do it in the log.”

  They fell into division of labour as if it had been written into the vessel.

  Saitō handled load: he reworked the soft sling into deck tie-down straps, making sure nothing bit into corners, making sure the force went into the cradle’s load beams. As he tightened he counted off, like calling a roll. “Strap one, strap two, strap three. Leave slack in each. A wave hits, and the ones you’ve cinched to death are the first to fail.”

  Anika handled steady-state: she switched the power page into return transit attitude; dynamic positioning (DP) moved from “fine operations” to “transit steady-state”; thrust vector returned to the economical setting. As an afterthought she locked the deck camera’s external broadcast down to the bone. “Evidence stays onboard. Entertainment stays offboard.”

  Keiko handled sealing: exterior shots, seal close-ups, numbering, strap paths—photograph first, write second. Her tone was unhurried, but every line was necessary. “Custody number. Dual-sign tamper seal. Exterior note: old-world industrial reserve container; contents high-value industrial consumables. External description: ordinary salvage.”

  Raphael handled the muscle work and the human weather: he shoved pulleys, tensioners, chocks into place, and kept the air from tipping over. “No heroics today. We’ve spent our allowance. From here on, it’s just being petty.”

  Saitō didn’t look up. “Petty keeps you alive.”

  Raphael bared his teeth in something that might have been a grin. “Did you hear that? Saitō just praised me.”

  Keiko, without warmth, corrected him. “He praised ‘care’, not ‘you’.”

  Anika, gloved, patted the strap buckle once. “Secured. Check it again. One loose strap and on the passage home this becomes a flying block of iron.”

  Saitō glanced at the sea-state window. “We take the fastest safe window back. No shortcuts. No storm corridor.”

  Raphael unscrewed his insulated cup and took a mouthful, his voice dropping with it. “Home. Seal it. Keep mouths shut. Understood.”

  When Gray Whale turned, a wave struck from the side and a sheet of water slid across the deck as if someone had thrown a bucket of cold over the boat. The container was strapped so tight it couldn’t move, and yet its weight still made itself felt—not on the steel, but on the mind. This was not a return passage empty-handed.

  The shipboard AI began to speak return parameters, as even as ever:

  “Return route generated. Estimated arrival at home-port window: thirty-eight hours. Recommendation: avoid high-risk sea-state bands. AIS: maintain normal broadcast.”

  Keiko logged the return timecode. “Log: operations complete; return transit initiated. Cargo secured. Sealing procedure complete.”

  Raphael leaned on the rail and watched the surface; wind made a mess of his hair. “You know, for a boat this small, out here… we’re rather like a fishbone.”

  Anika didn’t look up from the signal page. “Yes. Fishbones are notorious for lodging in other people’s throats.”

  Saitō watched the plotted line. “Then don’t become the fishbone someone decides to pull.”

  Not long after he said it, the AI’s alert tone turned shorter—sharper.

  The shipboard AI inserted, abruptly: “AIS receive buffer: anomalous short message detected. Strength: weak. Duration: 0.7 seconds.”

  Anika glanced. “Could be wave reflection. Could be someone probing with power throttled down. Log it.”

  The next second the anomaly vanished, as though wiped away by seawater.

  The air inside the bay felt briefly pinched.

  Raphael straightened. “Anomaly? Vessel, or noise?”

  Anika looked up at last; the clause-voice fell away into judgement. “Not noise. Noise doesn’t keep time.”

  She pulled up the AIS list. On it was a faint point that came and went—blinking in fog. It never held a clean identity code; now and then it spat out a fragment of data, then disappeared again.

  “Low-power tailing,” Anika said. “Someone’s out at range on minimal output. They want to see which line we take, but they don’t want us to see who they are.”

  Keiko’s finger paused for a fraction, then carried on. “Log: anomalous AIS return during return transit; bearing stern-starboard; intermittent weak signal; tailing suspected.”

  Raphael kept his voice down. “All this because we hauled one box of seals? That’s absurd.”

  Saitō’s eyes stayed on the route. His tone didn’t rise. “Not absurd. When supply breaks, a box of seals is a life. Someone catches the scent, they follow.”

  Raphael frowned. “But we didn’t say anything.”

  Anika’s reply was colder. “You don’t have to. You come up too clean from the seabed and you look like a pocket with something in it.”

  She opened another page. “And there’s this: we held station a long time. Extended the operations window. If anyone was sweeping that patch of sea and caught the rhythm of work up top, they’ll guess we recovered something—at least that it was worth risk.”

  Saitō asked, “Range?”

  “Not close,” Anika said. “Far. Far enough you won’t see their light. Close enough to sit on your wake.”

  Raphael wanted to swear; he swallowed it. “So what do we do? We can’t vanish.”

  “We can,” Saitō said. “The dullest way.”

  He lifted a hand. “Anika—keep AIS normal, but introduce micro-jitter to the rhythm. Nothing illegal. No identity hopping. Just make their tracking model suffer.”

  Anika nodded once. “Understood. Rhythm adjustment within compliance.”

  Keiko lifted her eyes. “Put it in the log: adjustment is hazard-avoidance, not identity fraud.”

  “Mm.” Anika’s voice was dry. “I’ll keep the evidence.”

  Raphael looked at Saitō. “Do we speed up and shake them?”

  Saitō shook his head. “Speed tells them you’re frightened. Once you’re frightened, they’re certain you have cargo. Hold normal transit speed, stay in the safe window, don’t give them a chance to close.”

  Raphael drew in cold air and, for once, let the jokes drop. “Fine. We act as though nothing happened.”

  Anika added quietly, “And we all know it did.”

  Wind hardened. Fog thickened. Gray Whale cut a line across wet, cold paper. The container sat on the cradle strapped to immobility—mute iron proof.

  Keiko shut her tablet for a moment, voice low. “When we get back: first, straight into sealed storage—avoid the public offload lane. Second, we only hand over the portion that can be explained. Third, anyone asks, it’s ordinary salvage.”

  Raphael nodded. “In plain terms—no one learns what we pulled.”

  Saitō watched the black fog ahead. “Yes. We’re not getting rich right now. We’re staying alive.”

  Anika said nothing more, eyes returning to the screen. The weak point blinked again, as if smiling at distance.

  The shipboard AI added—still cold: “Anomalous short message repeated. Interval: near-regular.”

  This time Anika didn’t say could. “Noise doesn’t keep a schedule. Someone’s watching our track.”

  Keiko stamped the timecode, her typing heavier than before. “Log: anomalous signal repeated; human tailing suspected.”

  Raphael stared towards the horizon and lifted a hand. “Look.”

  Beyond the fogline, the sea carried a faint shadow. Not a wave. Not a bird. A hull. Too far to see class, flag, or marking—only a small point of light at the bridge, like a grain of cold fire in the dark.

  It was neither fast nor slow. It simply hung on the edge of their track, as though an invisible line had been tied to it.

  Keiko logged the sight, steady. “Log: distant single-vessel silhouette observed; suspected correlation with anomalous returns.”

  Raphael dropped his voice to its lowest. “We’ve only just hauled our livelihood up and already someone’s started hunting for us.” He stared into the fog and said, softly, “That’s it.”

  Anika answered, “Yes. We’re not imagining it.”

  Saitō didn’t turn his head. He gave the closing line as though nailing the chapter down:

  “Back to port. Seal it. Don’t let it smell what’s in our box.”
