The Dark Knight’s Last Case

He lunged beneath it as a section of rusted ductwork crashed into the water behind him. The impact threw a wave against his back and drove him into the wall. Pain flashed along his ribs. He held still until the room stopped tilting, then forced himself upright.

His glove found the wall.

The concrete was slick and pitted. His fingers closed around an old brass plaque half-hidden beneath peeling paint.

RECORDS - NORTH WING.

The file was close.

He activated the lens in his cowl. Thermal outlines bled through the dark: pipes, cables, the faint residual warmth of machinery. Then another shape appeared at the end of the passage.

Human.

Standing motionless beside the barred archive door.

Batman lowered his hand toward the batarang at his belt.

The figure wore a black coat fitted close to the body, its hem floating just above the water. Pale fingers rested on the lock panel. A dark wave of hair brushed one shoulder. She did not turn when he approached.

“You’re late,” she said.

Her voice carried cleanly through the corridor, low and amused.

Batman stopped ten feet away. “Step away from the door.”

“Still giving orders.” She glanced at the lock without touching it. “Even when the building is trying to drown you.”

“Who are you?”

“A woman with better timing than yours.”

The lock panel sparked beneath her hand. She withdrew it before the current could catch her. The security system had been dead for years, but Blackgate’s old infrastructure still held surprises. Water trembled around Batman’s boots as another current moved through the corridor.

He studied her posture. No visible weapon. No panic. She had entered through the same flooded wing and reached the archive before him. That made her either very capable or very well informed.

“What’s in the file?” she asked.

“You already know.”

“I know what was taken. I want to know what you think it is.”

Batman moved closer. “You don’t get to ask questions.”

“That’s the difference between us.” Her eyes found his through the cowl’s white lenses. “I ask them. You bury them.”

The words struck harder than they should have.

Behind her, the archive door shuddered as water pressure shifted. Its locking bars were old, but the steel had held against the flood. Batman drew a compact charge from his utility belt.

The woman watched him set it against the hinge.

“You could open it without explosives,” she said.

“Then you know how.”

“I know how you opened the west vault in 2009.”

His hand paused.

The corridor seemed to narrow around them.

She tilted her head. “You cut the power first. Waited seventeen seconds for the backup circuit to engage. Then you used the magnetic lock’s own surge to burn out the release.”

Batman looked at her more closely. “That case was never public.”

“No. It wasn’t.”

The charge beeped once.

“Move,” he said.

She didn’t.

Batman seized her by the coat and drove her against the bars. Water splashed up around them. She made no sound, but her hand came up fast, a slim blade flashing between two fingers. He caught her wrist before the point reached his throat.

For one suspended second, they were close enough for him to see the fine scar beneath her jaw and the rainwater beading on her lashes. She smelled faintly of gun oil and expensive perfume, an incongruous trace of another world beneath the damp concrete and rust.

“You’re stronger than you look,” she murmured.

“You talk too much.”

“Not when it matters.”

She twisted, using his grip against him. The maneuver was familiar - not the technique itself, but the confidence behind it. She expected him to compensate for his bad knee. He did, shifting his weight and driving her wrist against the bars.

The blade dropped into the water.

The charge beeped again.

Batman released her and stepped back. “Last warning.”

She looked at the device, then at him. “If you breach that door, the lower archive floods completely. The file will be ruined.”

“You came here for it.”

“I came here before the pumps failed.”

“Why?”

“Because someone wants the past erased.”

“That’s not an answer.”

“It’s the only one you’re getting.”

Batman thumbed the detonator.

The blast punched through the corridor. Steel screamed. The archive door buckled inward, and a wall of black water burst through the opening. It struck Batman at the waist and drove him backward. His shoulder hit the opposite wall. The woman vanished beneath the surge.

For a moment, he saw nothing but bubbles and torn paper.

Then his hand closed around a hanging cable. He locked his arm, stopping himself from being swept into the archive. The cable cut into his glove. His knee slammed against a submerged step.

He heard metal scrape.

The woman surfaced beside the broken door, one hand gripping the frame. Her coat had torn at the shoulder. She looked toward him, her expression sharpened by the emergency lights.

“Still alive?” she called.

Batman pulled himself through the doorway.

The records room was a drowned maze. Shelves rose from the water in crooked rows, their upper levels lost in darkness. Filing boxes had burst open, releasing photographs, arrest reports, and handwritten statements into the current. A desk floated past with a typewriter chained to its surface.

His lens caught the faint heat of a recently handled object near the back wall.

He waded toward it.

The floor dropped without warning. Water surged over his chest. His cape dragged behind him, heavy as a net. He released the clasp and let it go. The loss irritated him more than it should have. The cape had been with him through too many nights to become disposable simply because his body had begun keeping score.

A shelf collapsed to his right.

Batman dove beneath it as metal teeth tore through the water. His shoulder scraped concrete. He came up beneath a low ceiling, trapped between the fallen shelf and the wall.

The woman appeared on the other side of the wreckage.

“You’re going to drown for a file,” she said.

“Get out.”

“Not without what’s in there.”

She reached through the gap. Batman caught her forearm.

Her gaze dropped to his hand. “You can’t hold me and search at the same time.”

“I can hold you.”

A smile touched her mouth. “That wasn’t what I meant.”

She drove her knee into the gap. The shelf shifted. Batman’s grip loosened just enough for her to slip free. He reached after her, but his fingers closed on empty water.

The room groaned.

A pressure valve ruptured overhead, blasting steam into the darkness. Batman turned his face away as heat scalded the side of his cowl. Through the white haze, he saw the woman climb onto a tilted cabinet and reach toward a metal drawer near the ceiling.

She pulled out a black evidence envelope.

Batman fired his grapnel. The hook caught the envelope’s metal clasp and tore it from her hand. The cable snapped taut. He reeled it toward himself.

She laughed once, breathless and irritated.

“You always did prefer distance.”

Batman caught the envelope as it struck his chest.

The seal had been broken. Inside lay a thin case file wrapped in oilskin, along with several photographs and a single loose page covered in his own handwriting.

Not recent handwriting.

The notation at the top belonged to a case he had closed years ago, one that had never reached a courtroom and never appeared in any official record. A sequence of symbols marked the margins. He remembered writing them in the Batcave at three in the morning, convinced the pattern meant something. Then another case had taken priority. The notes had gone into storage.

He had forgotten them.

She had not.

“Give me the page,” she said.

Batman tucked the file beneath his armor. “Why?”

“Because you don’t remember what you found.”

“I remember enough.”

“No.” She stepped down from the cabinet. “You remember the part that let you sleep.”

The words were quiet now. Without the teasing edge, they carried something closer to anger.

Water rose around them.

Batman held the page between two fingers. “Tell me who sent you.”

“You know who sent me.”

“If I did, you wouldn’t be standing.”

Her eyes moved over his face, lingering at the edge of the cowl where exhaustion had begun to show despite the armor and discipline. “That’s the trouble with you, Batman. You think every answer has to be beaten out of someone.”

“You came armed.”

“So did you.”

“I’m not the one stealing evidence.”

“No.” She took one step closer. “You’re the one who made it disappear.”

The accusation opened a door in his memory.

A warehouse fire. A witness who changed her statement. A name removed from a report because exposing it would have put three families at risk. His decision. His notation. His assumption that the danger had ended when the trail went cold.

The woman watched recognition move across him.

“There,” she whispered. “Now you remember.”

A violent tremor passed through the floor. The remaining shelves began to topple. Batman shoved the page into an inner compartment and grabbed the woman by the waist as the water threw her sideways. They crashed against the archive door together.

For an instant, her body pressed against his, warm through the soaked fabric. Her hand braced against his chest. He felt her breathing change.

Neither of them moved.

Then she looked up at him. “You should let me go.”

“You first.”

“That’s not how this works.”

“It is tonight.”

She smiled, but there was no humor in it. “You’re getting old.”

Batman released her.

She used the opening immediately. A small capsule struck the water between them and burst into a cloud of silver vapor. His lenses flared white. He swung blindly, catching only the edge of her coat.

The woman tore free and ran.

Batman staggered after her, one hand against the wall. The vapor burned his eyes even through the filters. He heard her boots strike the submerged steps, then the clang of a maintenance hatch opening above.

He fired the grapnel toward the sound.

The hook caught metal. He pulled himself up through the hatch just as the records room gave way beneath him. Water roared into the lower archive, swallowing shelves and evidence in a grinding black torrent.

He hauled himself onto the service walkway and rolled onto his back. The file remained secured beneath his armor.

The page did not.

Batman turned his head.

At the far end of the walkway, the woman stood beneath a failing red light. She held the loose page between two fingers. His old notation showed in the intermittent glow.

“Your past is not buried,” she said. “It’s waiting.”

Then she stepped backward through the open hatch and disappeared into the prison’s flooded underworks.

Batman rose, slower than he wanted, and reached for the grapnel. The line had snapped.

Below him, Blackgate groaned around its drowned records. In his hand, the recovered file felt heavier than paper should.

He looked at the empty space inside his armor where the page had been.

The case was back in his possession.

The investigation was not.
