The smell of wet lime and cold, stagnant water never completely left the sub-basement of the Kaiser-Friedrich-Museum, even eight years after the bombs had stopped falling. Herr Heinrich Roth dipped a fine sable brush into a porcelain saucer of rabbit-skin glue, his spotted hand steady despite the damp chill creeping through his felt boots. He was sixty-eight years old, though the war had given him the weathered countenance of a man a decade older, his spine bent from forty years spent stooping over damaged masterpieces. Above him, beyond two layers of vaulted brick and a mountain of crated marble debris, the Soviet sector of Berlin was waking up to the clatter of streetcars and the distant rhythm of jackhammers along Stalinallee.

Heinrich adjusted his spectacles, secured to his ears by a piece of frayed twine, and squinted at the panel before him. It was a sixteenth-century Flemish depiction of St. Jerome in his study, the oak board split clean through the cardinal's red hat during the artillery bombardments of 1945. For three months, Heinrich had worked in near total obscurity, using smuggled linseed oil, chalk, and pigments salvaged from the ruined storerooms. To the authorities in the Soviet sector, he was merely an unpaid inventory clerk tasked with cataloging worthless plaster casts and shattered frame fragments left behind when the Western Allies had evacuated their troops from the sector. They did not know about the steel door behind the boiler room, nor did they care about the old man who preferred the dark beneath the rubble to the propaganda banners drying in the streets above.

A sharp, metallic scrape echoed down the vaulted corridor outside his improvised workshop.

Heinrich froze, the paintbrush hovering a millimeter above St. Jerome’s nose. He listened intently, his breath catching in his throat. The sound was too light for the boots of a Volkspolizei patrol, which invariably clattered with the heavy rhythm of iron heel-irons. This was a hesitant sound—a heel catching against a loose piece of mortar, followed by the muffled drag of a heavy shoe.

Slowly, Heinrich lowered his brush onto a rag soaked in turpentine. He reached beneath his workbench, his fingers brushing against the cold, heavy iron of an unexploded 20mm shell casing he kept as an improvised cosh. He rose from his stool, his joints popping in the quiet cellar air, and blew out the oil lamp, plunging

The darkness in the sub-basement was absolute, thick as dried bitumen and heavy with the dust of dead brick. Heinrich stood behind the rusted frame of an iron drying rack, his back pressed against the weeping lime wall. His ears strain against the quiet. The scrape came again—closer now—accompanied by the soft, ragged wheeze of someone drawing air through a throat coated in grit. It was not the heavy, measured tread of a Soviet guard or the crisp step of an East German party functionary checking on state property. It was the movement of something wounded or hunted.

Heinrich lifted the brass casing in his right hand. The metal was cold enough to numb his fingers, but the weight offered a grim sort of comfort. He knew every shadow, every uneven flagstone in this corner of the foundation. If an intruder came around the corner of the brick buttress, Heinrich could strike before the intruder’s eyes adjusted to the pitch-black air. He held his breath, the bitter taste of stale turpentine lingering on the back of his tongue.

A faint beam of light cut through the gloom. It did not come from an electric torch, which would have thrown a hard, white circle across the vaulted ceiling, but from a small, battered storm lantern with a cracked glass shade. The yellow flame flickered weakly, illuminating a pair of shoes that had seen better decades. The leather was split along the seams, bound together with wire and grey twine, the left sole flapping loose against the floor. Above the shoes were threadbare trousers of rough woolen cloth, caked with dry mud up to the knees.

The figure stopped just past the entrance of the steel door. Heinrich watched from the shadows as the lantern was raised. The light brushed across a young face—hardly more than twenty, though etched with the grey fatigue common to those who lived on watery soup and bad coal. The boy’s hair was chopped short, unevenly cut as if with sewing scissors, and a crust of dark, dried blood ran from his hairline down across his left temple. He wore a coat three sizes too large, the hem trailing in the damp silt on the floor.

"Hello?" the youth whispered. The voice was thin, cracking slightly on the second syllable. It carried the distinct, soft cadence of the Saxon countryside, a far cry from the sharp, clipping dialect of Berliners. "Is anyone there?"

Heinrich did not move. A Saxon in the Soviet sector with a bleeding head and wire-bound shoes was a hazard. In the spring of 1953, people did not wander into the ruined foundations of Museum Island unless they were hiding from someone, or looking for something that did not belong to them.

The boy took two timid steps forward, his free hand clutching the lapels of his oversized coat against the cellar chill. He stumbled over a stack of broken red roof tiles, catching himself against the edge of Heinrich’s empty worktable. The lantern tipped sideways, sending wild shadows dancing across the brick vault. As he straightened the lamp, the boy’s eyes fell upon the Flemish panel sitting under the cloth-covered frame—or rather, upon the saucer of glue and the jars of ground pigment neatly arranged beside it.

"God above," the boy murmured. He reached out a trembling hand toward a glass jar filled with raw umber, his fingers hover over the lid as if it were made of hot iron. "There’s... there’s someone living down here."

"Touch that jar, and you will find out how quickly an old man can swing six pounds of brass," Heinrich said, stepping out from behind the drying rack. His voice was low, flat, and raspy from disuse, vibrating off the low brick ceiling.

The boy gasped, jumping back so fast his loose sole slapped hard against the flags. He raised the lantern like a shield, the flame flickering wildly as his hand shook. "Don't come near me! I have... I have nothing you want!"

"That is abundantly clear," Heinrich said, keeping the shell casing raised, though he shifted his posture slightly so the light hit his face. He wanted the boy to see his grey hair, his apron stained with rabbit glue, and his thick wire spectacles. An old man was less likely to provoke a panic-driven attack. "You are trespassing in a restricted area of the Staatliche Museen. The Volkspolizei patrol the perimeter every two hours. If I raise my voice, they will be down these stairs in three minutes."

It was a lie, of course. The Volkspolizei rarely bothered with the subterranean vaults under the ruined north wing; they preferred the warm guard hut near the Monbijou Bridge, where there was black bread and warm ersatz coffee. But the threat had its intended effect. The boy’s face drained of what little color it possessed.

"Please," the boy whispered, his eyes darting frantically toward the dark passage behind him. "Don't call them. I'm not a thief. I didn't come to steal anything. I just... I needed to get off the street before daylight."

"People who belong on the street do not bleed from the scalp and wear coats meant for a butcher," Heinrich observed dryly. He lowered the brass casing an inch, though he did not drop it to his side. "What is your name?"

The boy hesitated, his chest heaving under the bulky coat. "Erich," he said after a beat. "Erich Weber."

"And where did you come from, Herr Weber? Because you did not walk here from the Alexanderplatz with shoes in that condition."

Erich looked down at his feet, then back at Heinrich. "From the yard at Treptow. I was on the freight train from Frankfurt an der Oder. I jumped near the canal when the train slowed for the signal." He swallowed hard, his throat making a dry clicking sound. "They were checking papers at the station. Everyone was being lined up against the fence."

Heinrich felt a cold prickle of apprehension behind his knees. Frankfurt an der Oder was the main transit point for the labor camps and the military zone near the Polish border. A boy coming off a freight train from that direction was either a deserter, an escaped prisoner, or a fool who had tried to cross the Oder without the proper stamps in his Personalausweis.

"And why were you in Frankfurt?" Heinrich asked, his voice hardening again.

"I was working at the brickworks," Erich said quickly, his words tumbling over one another as if he had rehearsed them in the dark corner of a cattle car. "They sent a brigade from our village. But the quota... they raised the quota last week. A man fell from the kiln platform, and when we stopped to pull him out, the supervisor said we were committing sabotage. They took three of us to the guardhouse." Erich touched the cut on his forehead with two grimy fingers. "I didn't stay to see what the officer had to say about it."

It was a plausible story. The Soviet Zone was full of such stories that year. The party was driving the workers to meet impossible targets for the five-year plan, and any resistance was met with the label of economic subversion. Yet, Heinrich knew better than to trust the first set of facts offered by a stranger in the dark. In 1953, truth was a currency far more precious—and dangerous—than the inflated Ostmarks in his pocket.

"You came down here through the coal chute," Heinrich said, pointing his casing toward a square opening high on the southern wall, where a heap of wet slag sloped down into the corridor. "Only someone who knew the old layout of the museum would know that chute leads beneath the main entrance."

Erich shifted his feet, his jaw tightening. "My uncle worked here before the war. In the maintenance department. He told me about the heating tunnels when I was a child. He said you could walk from the copper trench clear under the Spree if you knew the right doorways."

Heinrich fell silent. He remembered the maintenance crew from the late thirties—a set of quiet, soot-stained men who lived in the basement quarters near the boilers. Most of them had been drafted in forty-four and buried in the mud of East Prussia. If the boy had an uncle who worked here, it was possible he was telling the truth about the chute. But it also meant the boy knew the sub-basement had multiple exits.

"Your uncle gave you bad information," Heinrich said calmly. "The tunnel under the Spree was blown by the SS in April forty-five to stop the Red Army. It is full of stagnant water, dead rats, and unexploded mortar shells. There is no way through to the Western sector down here."

Erich’s shoulders slumped. The small spark of hope that had sustained him through the dark freight journey seemed to snuff out instantly. He lowered the lantern, setting it down on a flat flagstone with a dull clink. "Then I am caught."

"Not yet," Heinrich said. He stepped over to his worktable, set the heavy brass casing down beside his jar of rabbit-skin glue, and picked up a clean linen rag. He dipped the rag into a small earthenware bowl of boiled water he had set over a charcoal brazier an hour earlier. "Come here."

Erich looked at him suspiciously. "Why?"

"Because if you bleed on that Flemish panel, I will be forced to throw you into the canal myself. It took me six weeks to clean the mold off the frame, and I have no desire to restore it a second time because of your messy skull."

The boy stood still for a moment, then dragged his feet across the damp floor until he was standing beside the table. He smelled of coal smoke, unwashed skin, and the wet copper smell of fresh blood. Up close, Heinrich could see how hollow his cheeks were—the bone structure sharp and prominent, typical of those who had spent their formative years under the starvation rations of the post-war winters.

Heinrich pressed the warm, damp rag against the boy’s temple. Erich winced, his teeth clicking together, but he did not pull away.

"Hold it there," Heinrich commanded, taking the boy’s hand and placing his cold fingers over the cloth. "Press firmly. It is only a crease from an iron bolt or a brick edge. It will stop running presently."

Erich held the rag against his head, his eyes traveling over the items on the table: the small, delicate brushes with wooden handles worn smooth by decades of palm grease; the glass palettes covered in dried dabs of burnt sienna, lead white, and lapis lazuli; the iron clamps holding the split oak panel in a gentle, firm embrace.

"You're a painter," Erich said, his tone shifting from fear to a flat, dull curiosity.

"I am a conservator," Heinrich corrected, pulling his chair closer and sitting down with a faint groan from his knees. "A painter creates something new out of his own vanity. A conservator preserves what greater men made before the world went mad. There is a vast difference."

"The party says art must serve the rebuilding of the state," Erich said mechanically, as if reciting a line from a school textbook. "They have posters of the bricklayers at the corner of Friedrichstraße. Everything is red and yellow."

Heinrich let out a short, soft sound that was not quite a laugh. "The party knows as much about art as a mule knows about church music. They want posters because posters tell people what to think. A good painting asks people what they have forgotten." He adjusted his spectacles and looked hard at the boy. "What do you see on that wood?"

Erich turned his head slightly, squinting at the Flemish panel under the yellow glare of the storm lantern. The picture depicted St. Jerome sitting at a crude wooden desk, an open folio before him, a skull resting near his inkwell. Through the small arched window behind the saint, a miniature landscape stretched away toward blue hills and a tiny, perfectly rendered river.

"It’s an old man," Erich said slowly. "He looks cold."

"He was cold," Heinrich said. "He lived in a cave in the desert for four years. But look at his hands."

Erich leaned closer, his rag slipping an inch from his cut. "He’s holding a small knife. He’s scraping a mistake off the page."

"Precisely," Heinrich said softly. "He spent his life translating ancient words into a language people could understand. When he made an error, he didn't burn the book. He scraped the ink away, bit by bit, until the vellum was clean enough to try again." Heinrich leaned back, resting his spotted hands on his thighs. "That panel is four hundred years old. It survived the Thirty Years' War, the Swedish occupation, the French invasion, and two raids by American bombers. It will survive the Socialist Unity Party, provided I can keep the damp out of the joinery."

Erich looked at the painting for a long moment, then down at his own mud-stained knees. "They won't let me scrape it away," he said, his voice dropping so low Heinrich had to lean forward to hear it. "The paper at the brickworks... my file has a red mark on it now. Once you have a red mark in the register, you can't get a work permit in Potsdam or Magdeburg. You can't even buy bread without the clerk looking at you like you're a dead man."

"There are millions of red marks in this country," Heinrich said flatly. "The administrative offices in Leipzig are currently four years behind in sorting them. The state is not a giant machine, Herr Weber; it is a very large, very stupid dog. If you run, it bites. If you stand behind a pillar and keep quiet, it usually wanders off to bark at something else."

Heinrich reached into the pocket of his coat and produced a piece of hard, black bread wrapped in greaseproof paper. It was his evening ration, meant to sustain him through eight hours of tedious glue-setting. He broke off a third of the wedge and extended it toward the boy.

"Eat this," Heinrich said. "Then you are going to help me move three crates of plaster leg fragments from the hall. If the guard comes by at six, I want him to see two men doing useless work for the department of antiquities, not one old man entertaining a fugitive."

Erich looked at the bread, his mouth working silently as saliva flooded his tongue. He took it with both hands, his knuckles white and caked with dark grime. "Thank you, Herr..."

"Roth," the old man said, turning back to his worktable and picking up his brush. "Heinrich Roth. And remember this, young man: in this basement, we do not discuss the brickworks, we do not discuss Frankfurt an der Oder, and we do not discuss what is written in any register in Saxony. If anyone asks, you are my apprentice, assigned by the district cultural committee to help with the inventory of undamaged moldings."

"Will they believe that?" Erich asked between mouthfuls of the dry, sour bread.

"They will believe whatever saves them from having to carry six-hundred-pound crates up three flights of stairs," Heinrich said coldly. " bureaucratic laziness is the only reason half of Berlin is still alive."

He dipped his sable brush into the warm glue once more. Outside, far above the thick brick vaults, the first whistle of a steam locomotive shrieked through the morning grey over the Spree, signaling the arrival of the early train from the eastern territories.

By four o'clock in the afternoon, the light filtering through the high, barred air grates had shifted from dull grey to a bruised, muddy purple. The cellar grew colder as the ambient heat from the city above died away.

Heinrich watched the young man from the corner of his eye while pretending to measure the width of a baroque picture frame with a folding boxwood rule. Erich was surprisingly thorough for someone who claimed to be a farm boy from Saxony. He did not drag the plaster casts across the flagstones as the previous temp-workers had done; he lifted them by the base, balancing the weight against his chest with a slow, careful economy of movement that suggested he was used to handling things that broke easily.

"Not there," Heinrich said, pointing his rule toward a low niche in the southern wall. "The moisture from the street drain seeps through that mortar during rain. Put the torso on the dry timber near the stack of laths."

Erich adjusted his grip on the half-scale plaster copy of a Roman senator and set it down where he was told. He rubbed his wrists, which were red and chafed from the rough hemp rope he had used to tie his coat sleeves tight against the draft.

"You have good hands for this work," Heinrich said, not looking up from his ledger. He was writing with an old fountain pen, his script tight, angular, and black as iron gall. "Most young men today handle objects as if they were thrown out of an artillery piece."

"My father was a carpenter," Erich said. He immediately caught himself, his eyes flicking toward Heinrich with a sudden, sharp look of alarm. He had broken the rule about discussing the past.

Heinrich did not look up from his ledger. "A carpenter’s son should know the difference between white oak and pine. That Flemish panel is quarter-sawn Baltic oak. If the humidity drops below forty percent, the grain will pull itself apart like a wet shoe drying too fast near a stove. Remember that if you touch the damp cloths on the back."

Erich relaxed slightly, taking a deep breath of the turpentine-heavy air. "Why do you stay down here, Herr Roth? The museum is half-ruined. There are no visitors. Nobody comes down these stairs except the rats and the water-men."

Heinrich capped his pen with a precise click. He looked around the vault—at the stacks of dusty crates, the shelves filled with broken terracotta oil lamps, the plaster heads of gods and emperors stacked four high against the damp brick like skulls in a catacomb.

"In nineteen thirty-nine, there were seventy-four employees in this department," Heinrich said softly. "We had three restorers for panel paintings, two for textiles, a master gilder from Vienna, and six apprentices who did nothing all day but wash camel-hair brushes and grind cinnabar. By forty-three, the apprentices were in Russia. By forty-five, the gilder was buried in a mass grave near the Tiergarten, and the other restorers had fled to Munich with whatever they could carry in a handcart."

He reached out and smoothed the edge of the canvas cloth covering the Flemish panel. "The state thinks everything in these vaults was either destroyed by the English bombs or carried off to the Hermitage by the trophy brigades. They are mostly right. But they missed three rooms behind the old coal bunkers because the doors were buried under twelve feet of fallen marble from the main staircase. I spent six months digging through that marble with a cold chisel and a bucket."

Erich stepped closer to the table, his curiosity momentarily overcoming his exhaustion. "What is in those rooms?"

"Things that do not belong to the Socialist Unity Party," Heinrich said simply. "And things that do not belong to the Americans in Dahlem either. They belong to the building."

"And you're fixing them all by yourself?"

"I am keeping them from turning into mud," Heinrich said. "Which is all any of us can do until people stop burning books and shouting through loudspeakers."

A sudden, sharp metallic bang echoed down the vaulted corridor from the upper basement level—the heavy iron door at the foot of the central staircase had been unlatched from the outside.

Erich froze, his hand dropping to the wooden crate beside him. His eyes went wide with the quick, instinctual panic of a hunted animal.

"Under the stairs," Heinrich hissed, pointing his pen toward a narrow dark alcove where three empty packing cases were stacked against the damp wall. "Get behind the pine cases and do not breathe. If you drop anything, I will personally hand you over to the district officer."

Erich did not argue. He darted into the alcove like a shadow, his loose sole making no sound this time as he crouched behind the grey wood.

Heinrich calmly pulled a dirty greasecloth over the Flemish panel, picked up an iron rasp and a piece of coarse plaster, and began filing the edge of an old molding with loud, rhythmic scrapes. White dust fell over his spotted hands and the dark wool of his sleeve.

Footsteps approached. They were heavy, slow, and accompanied by the distinctive clinking of a sidearm swinging against a leather belt. A flashlight beam bounced off the vaulted ceiling, swinging wildly across the rows of plaster casts before coming to rest directly on Heinrich’s face.

Heinrich blinked against the glare, raising his rasp to shield his eyes. "Good evening, Comrade Lieutenant," he said in his flat, tired voice.

The man behind the torch was small and squareshouldered, wearing the grey tunic of the Volkspolizei with the blue collar tabs of the technical guard unit. His name was Schulze, a former Munich postman who had joined the party in forty-six to secure a warm apartment in the Prenzlauer Berg.

"Roth," Schulze said, lowering the beam slightly so it hit Heinrich’s chin instead of his eyes. "You’re still down here? The sun went down an hour ago."

"The light is bad during the day anyway," Heinrich replied, nodding toward the high grate. "I am finishing the inventory for the third sector. The district director wants the report on the plaster casts by Friday."

Schulze spat onto the flagstones, the white spit landing two inches from Heinrich’s boot. "Plaster. The whole basement is full of lime and smashed dirt. I don't know why the ministry pays you twenty marks a week to count broken feet."

"Nineteen marks and fifty pfennigs," Heinrich corrected mildly. "And they pay me because if the Soviet cultural commission comes to inspect the site, they expect to see every inventory number accounted for, even the broken ones."

Schulze walked around the worktable, his boots making a dry, crunching sound on the plaster dust. He stopped near the alcove where Erich was hidden. Heinrich’s heart gave a single, hard thump against his ribs, but his hand holding the rasp remained steady. He continued filing the piece of plaster with long, measured strokes.

"We had an alarm at the Ostbahnhof this morning," Schulze said, leaning against a stack of crates three feet from Erich’s hiding place. He pulled a crumpled pack of Karo cigarettes from his pocket and lit one with a greasy brass lighter. The smell of cheap, acrid tobacco immediately filled the cellar air. "Three boys jumped off the freight from Poland. One of them took an iron bar to a guard's face."

"Did they catch them?" Heinrich asked, his voice entirely devoid of interest.

"Caught two," Schulze said, blowing a cloud of blue smoke toward the ceiling vault. "One ran toward the river. The dog lost the scent near the coal yards. We’re checking every cellar between here and the Schilling Bridge."

"No one has been through here," Heinrich said, picking up a small hairbrush to sweep the white plaster dust from his table. "The outer latch was rusted shut until I opened it this morning. If anyone came down the chute, they would have broken their neck on the iron girders."

Schulze squinted into the dark corners of the vault, his torch beam sliding over the stacked crates, the broken torsos, and the dark entrance to the boiler room. For three agonizing seconds, the beam stayed fixed on the gap between the pine packing cases where Erich was crouching. Heinrich watched the light reflect off the steel nails in the wood. If Schulze stepped two paces to the left, he would see the boy’s mud-stained shoes projecting past the pallet frame.

"It’s cold enough down here to turn a man’s balls to ice," Schulze muttered, turning his back on the alcove and dropping his cigarette butt into Heinrich’s bowl of water. It went out with a tiny, sharp hiss. "Don't stay past eight. The night shift is locking the main street gates, and I won't come down here to let you out if you get yourself locked in with the ghosts."

"I will be gone by seven," Heinrich said.

Schulze grunted, adjusted his belt, and turned back toward the corridor. His heavy steps retreated slowly down the long brick vault, followed by the metallic thud of the outer door falling back into its frame and the sharp, double-click of the spring latch engaging.

Silence returned to the basement, thick and suffocating.

Heinrich waited three full minutes, counting the seconds by the steady drip of water from the ceiling pipe near the door. One hundred and eighty. Then he laid the rasp down on his table.

"You can come out now, Herr Weber," Heinrich said softly.

Erich stepped out from behind the crates. His face was green in the weak light of the storm lantern, his chest moving in shallow, rapid gasps. "He had... he had a dog at the bridge," he whispered. "I heard them barking near the timber yard."

"He is gone," Heinrich said. He looked at the boy’s hands, which were shaking so violently he could barely hold his oversized coat around his chest. "And you are a terrible liar. You did not come from the brickworks in Frankfurt."

Erich stopped shaking. His eyes cleared, hardening into that sharp, desperate look Heinrich had seen so often in forty-five. "I never said I was a saint, Herr Roth."

"The boy who hit the guard at the station was wearing a butcher’s coat," Heinrich said, pointing his thin finger toward the greasy, dark leather lapels of Erich’s garment. "I saw three men from the local abattoir wearing coats like that last winter. It has the grease of tallow on the seams, not clay from a brick kiln."

Erich pulled the coat tighter around himself, his mouth setting into a thin, hard line. "The guard was going to shoot my brother. He had him by the belt near the coupling housing. I used what was in my hand."

Heinrich sat back down on his stool. He looked at his spotted hands, then at the oil cloth covering the Flemish master. The air smelled of saltpeter, cold mud, and cheap tobacco smoke—the true scent of Berlin in the ninth year of the peace.

"Your brother?" Heinrich asked.

"They took him onto the third wagon," Erich said, his voice dropping into a flat, deadly register. "The wagon with the barred vents. He didn't jump in time."

Heinrich nodded once. He reached under his table, picked up the small saucer of rabbit-skin glue, and set it over the tiny charcoal flame of the brazier to keep it from setting hard overnight.

"The second door behind the boiler room has three dry blankets and a sack of dry laths," Heinrich said, his eyes fixed on the small yellow flame under the pot. "There is a bucket of clean water from the well in the courtyard behind the cistern. Wash that blood off your head before it turns sour."

Erich stood still for a moment, looking at the old man’s bent back. "Why aren't you throwing me out?"

"Because if you leave now, Schulze’s dog will find you before you reach the Weidendammer Bridge," Heinrich said plainly. "And if they find you near the museum, they will search every vault down here with iron bars and crows. I have forty-two panels left to clean, Herr Weber. I cannot afford to have the Volkspolizei turning my workshop into an interrogation cell."

"I can work," Erich said quickly. "I can carry the heavy timber. My father... he really was a carpenter. He taught me how to join oak without iron nails."

Heinrich raised his hand to stop the boy’s words. "Tomorrow we will see if your father taught you anything useful. Tonight, you stay behind the steel door, you do not light a match, and if you hear boots above, you lie on the flagstones and act like a piece of dead lime."

Heinrich stood up, pulled his ancient wool cap down over his ears, and took his battered leather briefcase from beneath the bench. He turned off the small storm lantern, leaving only the tiny, deep-red glow of the charcoal brazier to cut through the subterranean gloom.

"Goodnight, Herr Weber," Heinrich said, his footsteps already echoing toward the dark passage leading to the street exit.

"Goodnight, Herr Roth," the boy’s voice came from the darkness near the boiler room, small and thin, barely louder than the weeping of the wet brick walls.

Heinrich walked up the narrow stairs toward the light of the ruined street, his knees aching with every step, carrying the weight of two secrets now—one wrapped in linen under a board on his worktable, and another sleeping on a pile of dry laths beside the dead boilers of the Kaiser-Friedrich-Museum.
