3 Federal Archives

Koblenz, Germany — Das Bundesarchiv

Koblenz wore its age well—sharp rooftops under a lid of slow grey cloud, river air cool enough to make a man zip his jacket. The confluence breathed its damp into the stone; gulls needled the air with small arguments; a barge slid past like a slow decision.

Inside the Federal Archives, the smell was old paper and bureaucracy: dust tamed into rules, metal shelving in endless ranks, files numbered with German certainty, silence measured in fluorescent hum. The sort of place where history didn’t sleep so much as hold its breath.

Sean and Terry followed a sterile corridor, boots echoing against linoleum that looked perpetually mopped.

“I can’t believe your dad sent us here,” Terry muttered. “Bet we’re about to meet some buck-toothed, hairy-backed, knuckle-dragging archivist from hell.”

They turned a corner and stopped.

The woman by the security door was not a troll. Tall, composed, blonde braid over one shoulder; Bundeswehr green sitting like she’d been poured into the decision to wear it. A small beauty mark lived under her left cheekbone, more signature than flaw. Her eyes held light and calculation in the same breath.

“Gentlemen,” she said, offering a hand. “Dr. Silvia Petrov.”

Terry blinked. “She’s a very hot do—”

Sean’s elbow found his ribs.

“Oof.”

Sean recovered with a professional smile. “Sean Carter. This is… Dr. Loser.”

Silvia tilted her head. “Doctor… Loser?”

“Long story,” Sean said. “We’re looking for records on a prototype. World War II. APG Mark I.”

“Armour-piercing gun,” Silvia answered without missing a beat. “Come.”

Her badge tripped the maglock with a soft thunk. She led them through a decontam air-curtain that breathed cool across their faces and into the stacks: cage doors, red-tagged boxes, aisle numbers in a font that had never once smiled.

“Phones off,” she said over her shoulder. “Gloves on when handling originals. No pens—pencils only. If you sneeze, sneeze away from the nineteenth century.”

Terry lowered his voice. “I like her.”

“I’m confident she heard that,” Sean said.

Silvia keyed them into a records room with a central worktable, a microfiche reader squatting like a stubborn insect, and the promise of dust. She flicked on a task lamp; light pooled across scarred wood.

“We have little on the weapon itself,” she said, hauling boxes. “But ammunition programs—yes. Logistics sometimes remembers what R&D wants to forget.”

They read the war the way archivists do—through its supply chain and the paper it shed. Convoy manifests, coded logs, requisitions stamped in fading ink. Fragments: field tests cancelled, crates redirected, units that existed on paper and then didn’t. Names that appeared for six months, then vanished into a clerk’s shrug.

Sean’s pencil was an instrument, not a fidget. He circled dates, drew arrows between initials that repeated across departments. “This one—H.K.—signs off on ammo requisitions and rail clearances. H. Koerner? Kappel? Doesn’t matter yet.”

“Geheimhaltungsstufe,” Silvia murmured, tapping a stamp. “Secrecy level. Tier three. You didn’t get that for experimental boots.”

Terry mimed a rifle. “Long grey thing—pew pew—”

“I’m confident she knows what a gun is, Tez,” Sean said dryly. “Development window puts it around ’43.”

Silvia’s mouth tugged, almost a smile. “Your father said the same.”

Sean didn’t look up. “Of course he did.”

Silvia unlocked a narrower cabinet, slid out a long roll—oiled paper that remembered the touch of hands that were ash now. She unfurled it across the table with the careful impatience of someone good at their job.

“Here is your APG.”

Blueprints in crisp lines: a profile like an MG-42 trimmed for speed; modularity closer to an early carbine; the kind of engineering that made you feel a little guilty for admiring it. Notes marched in tidy German: adjustable caliber, standard load 7.62 mm armour-piercing, quick-change barrel, magnetic feed assistance, experimental recoil sink. Margin stamps signed in a blocky hand that didn’t bother to be art.

Terry whistled low. “Nasty little bastard.”

“Not ‘just a gun’ if my father’s chasing it,” Sean said. “There’s always an and.”

Silvia tapped a materials block in the corner. “Look.”

Sean squinted. Stopped. The pencil’s tip lifted a millimetre.

Terry read aloud, because silence would have made it bigger. “Titanium alloy… and—wait—Mondgestein-Verbundstoff? Moon-rock composite?”

Silvia blinked once. “That makes no sense. Even now, lunar samples are controlled to the gram. You’re telling me the Nazis had—”

Sean flipped a test booklet they’d set aside, skimming underlines that had bled through the paper. “Italian range trials. Sardinia. Lightweight, handheld, effective range reported at five thousand meters.” He looked up. “They claim it tore through tank armor like wet cardboard.”

Terry stared, then gave it the correct word. “That’s not a field gun. That’s a battlefield rewrite.”

Silvia’s mouth thinned. “Portable, modular, armour-erasing. In the wrong hands, you don’t win battles—you erase them.”

Silence reoccupied the room, respectful for once. Somewhere down the corridor, a trolley squeaked past like a mouse that had learned to alphabetize.

Sean unrolled a weathered military map from another box, pinning the corners with thick binders. Brown rivers bled into beige; a thousand creases told you how often it had been folded in hurry.

“Here.” His wax pencil drew a vein across Europe. “Transport out of Berlin by convoy. Referenced here as a Geisterzug—‘ghost train.’ That’s not a nickname you hand out at random.”

Silvia leaned in, braid falling forward; Terry mirrored her, careful not to crowd. The three heads made a conspirators’ triangle over the paper.

“It skirts Italy,” Sean said, dragging the line south through a tumble of towns. “Switches rail heads twice. Ends… somewhere in Greece. No precise grid. Just ‘gesichert im südlichen Gebiet’—secured in southern territory.”

“A ghost train,” Terry said. “You sure this isn’t an Indiana Jones collectible?”

“Jones never had to fill out Form 27-B for reading a map,” Silvia said. The dryness qualified as humour, barely.

Sean kept moving across the table, pulling a box labelled AMMUN/ITALIA/’44-’45. He cracked the lid, sifted folders by touch and habit. “Requisitions for ‘special load’ transhipment. Sardinia range report again. A note here—‘Schachtel counts do not match manifest.’ Box counts. Someone nicked inventory mid-route.”

“Or swapped it,” Silvia said. “If the weapon is one thing, its ammunition is the crown jewels. Composite or not.”

“Moon-rock,” Terry repeated, tasting it. “How the hell—”

Sean didn’t answer. The answer didn’t matter today. Today was roads and rails and where the trail died.

Silvia slid a slim drawer from the side of the table and fed a microfiche card into the reader. The screen woke with a square of black and bureaucratic white. She rolled the wheel, images stuttering past: a colonel’s signature; a receipt; a complaint about shoddy packing from someone who’d never been shot at.

“There,” she said, arresting the frame. “Italienische Erprobungsergebnisse—Italian trial results—forwarded to Einsatzgruppe E liaison.”

Terry frowned. “Einsatzgruppe… E?”

“Occupation administration in Greece, ’43 to ’45,” Sean said. “Anti-partisan work, logistics, ports. If they touched it, it went south.”

Silvia tapped the lower margin. “And then there’s this code: Seeschlange. Sea serpent.”

“Convoy codename,” Sean said. “Naval or coastal transfer.”

“So rail to Italy, sea toward Greece,” Terry said. “Your ghost train buys a ferry ticket.”

Sean’s jaw set. He looked back to the map, to the red line dying into ambiguity over Greece. His father’s shadow seemed to lengthen across the paper, even in this antiseptic light.

“What happens if it falls to someone worse than your father?” Terry asked quietly.

Sean didn’t answer. He didn’t need to. The room understood subtraction.

Silvia tapped the map’s southern smear. “Southern territory in ’45 could mean Peloponnese railheads. Nafplio. Kalamata. Patras if they were cheating. Even Crete, if they risked sea transfer. The Germans pulled back to the islands late; they liked caves and altitude.”

“Crete,” Terry said, as if tasting the salt on the word. “You ever been?”

“Once,” Sean said. “Didn’t end with cake.”

He rolled the blueprint back a fraction, studying the materials block again as if it might confess. It didn’t. The word sat there—Mondgestein—as casual as if you could order it by the kilo.

Silvia reached for a thin folder with a different weight. “These are personnel rosters. You flagged H.K.—here. Hans Koerner, logistics. Shows up on ammo requisitions and rail clearances. Last orders put him in Athens in April ’45 with authority to ‘secure special materiel against enemy seizure.’”

“Which could mean hide it,” Terry said. “Or drown it.”

“Or move it somewhere the Allies wouldn’t think to look,” Sean said. “Somewhere sacred. Somewhere stupid. They loved both.”

He flipped the map to its reverse—creases breaking like old bones—and found a coastal inset. “If you were offloading in ’45 with the Med trying to murder you, you’d use smaller harbours. Kalamata fits. Nafplio fits. Crete… needs guts and audacity.”

Silvia glanced at her watch, then at the door. “We have thirty minutes before this room becomes a pumpkin. You can request scans, but originals don’t leave.”

“Copy these,” Sean said, sliding the blueprint to a measured stop. “Map, materials block, Koerner’s orders, Seeschlange reference.”

Silvia nodded and moved with practiced economy—gloves, flatbed, calibration strip—before the scanner’s light bar crawled its slow comet across the paper. She saved to a secure drive, ticked boxes with a pencil that shaved wood as it wrote.

Terry, who had been unusually quiet, finally spoke. “So… moon-rock bullets.”

“Composite,” Silvia said automatically, as if pedantry were a shield. Then, softer: “If true.”

“If true,” Sean echoed. He packed away the map with an ease that looked like gentleness. “And even if that’s smoke, the range and penetration claims aren’t.”

Silvia met his eyes over the table’s edge. Professional. Curious. Aware he was not telling her everything and choosing to proceed anyway. “Your father said you move fast.”

“He would.” Sean capped the wax pencil. The red line he’d drawn bled across two countries and a sea. “Where he likes speed, I like angles.”

“Good,” she said. “Because Greece has both.”

The room’s overhead lights flickered once—the archives’ polite way of clearing its throat. Closing soon.

Sean gathered what was theirs to carry: scans receipt, pencil notes, copies of copies. He left what wasn’t: the weight of the blueprint and its obscene little materials box, the scent of old glue, the sense of having touched something you shouldn’t have and wanting to wash your hands after.

Silvia sealed the boxes, signed the chain-of-custody sheet, and handed Sean a duplicate. “I’m on secondment,” she said, almost as an afterthought. “Bundeswehr to Interpol liaison. I can travel.”

Terry brightened. “Outstanding.”

Sean slid the paper into his folder. “We leave before anyone has time to remember why we shouldn’t.”

Silvia keyed the door; the maglock thunked them back into the corridor. Fluorescents turned skin to office tones. Somewhere, a clock made an effort no one had asked it to.

At the exit, the guard checked their passes with the ritual care of a church usher. Outside, the air hit colder, cleaner, as if the building had been holding it for them.

They stood a moment under the grey, the river’s breath in their lungs. Trucks whispered along the far bank; a cyclist drifted past wrapped in neon and indifference.

“So,” Terry said. “Peloponnese? Kalamata? Nafplio? Crete if we’re feeling like idiots?”

“We do what we always do,” Sean said.

Silvia tilted her head. “And if that isn’t enough?”

Sean looked south as if he could already see the water, the ferries cutting their stitched lines across it, the mountains that rose like the backs of sleeping animals.

“Then we find out when we get there.”

He started toward the car. Behind them, the archives swallowed their breath again and went back to doing what it did best: keeping secrets until someone insisted.
