Chapter 1:

The Man in the Black Coat

Bloodline Zero


It's hard to tell your mother you weren't coming home while standing still.

Mara learned that about herself very quickly, and so she kept walking.

She passed by the bus shelter, the coffee cart and the bright white billboard where a woman in a lab coat smiled down through the morning rain.

LUMEN. A safer tomorrow. Together.

Mara looked away before the smile could start feeling personal.

The phone was warm against her ear. The folder in her crossbody satchel bumped against her hip with every step. Inside was a Calder–Lumen Emergency Medicine Fellowship. Orientation schedule, badge pickup, and housing confirmation with clean pages and sharp corners. Her whole new life was printed out and placed inside of a brown bag.

She'd gotten a paper cut that morning, forcing the folder into her satchel, one white corner catching skin before she felt it. It was small and easy to ignore, but the thin paper cut along her thumb opened again.

She wiped it against her pant leg and kept walking.

"I'm not asking you for permission," she said.

Mara's mother went quiet.

"You seriously signed a lease without telling me?" her mother finally asked.

"I told you that I was going."

"You said you were thinking about going."

"I only said that because I knew that you would panic."

"Mara!"

As she crossed with the light, she tightened the grip on her phone. If she had stopped, she would picture the apartment she'd left. The boxes she packed too fast inside of a bedroom she had been in for too long, and everything she left behind because it would've taken too much time to grab them.

"The medical program starts tomorrow," she said. "I've already signed and I've already moved in."

"Mara, you don't know anybody in Calder."

"That's kind of the point, mom. I needed something different, something new."

Across the street, under the edge of the big white billboard, a man had been standing still, like he'd caught something no one else did.

He was the only person not moving, waiting for something, which was why Mara noticed him. He stood near a vendor cart with his hands loose at his sides, looking toward the office tower halfway down the block.

The building had a glass face with a polished stone lobby. There was a small white Lumen clinic sign built into the ground-floor directory. It was clean and forgettable.

The man was looking at it like he was trying to burn it down with a long hard stare, eyes fixed on either the building or something inside it.

Mara's mother inhaled on the other end of the call, slow and careful. She was probably in the kitchen with one hand on the counter, eyes closed with disappointment painted on her face.

"I just want to protect you, Mara," she said.

"Yes, I know, mother."

"No you don't, but maybe someday you will."

Mara was just about to answer her back when the building groaned.

It was deep, and wrong, so out of place that an entire half of a block turned toward the building and froze.

The odd man who had stopped before everyone else didn't turn with the crowd because he was already looking up at the third floor.

The windows suddenly started to bow outward. Each pane held for half a second.

Then a man came flying through them backward and landed on a parked car, caving the roof in and smashing it flat.

Mara's phone slipped against her cheek, almost out of her hand.

"Mara? What was that?" her mother said.

The front of the building folded inward, then the lobby exploded toward the street, steel screaming and glass raining down harder than the water from the sky.

People panicked and ran without understanding what from, then a figure stepped through the broken entrance.

It looked human to Mara, at first. She saw a work jacket, a single black dress shoe, a belt still looped through a waist that had changed shape. The details didn't belong on a monster, so for a moment they made the body harder to understand.

The person that used to be there was gone.

The creature's gray skin stretched over a frame that didn't make sense to the untrained human eye. Its arms were too long, its fingers looked more like claws and scraped black marks into the pavement. Its face looked more like an armored mask, and the sound it made put the whole street into motion.

Mara should have run with the rest of them but her body just wouldn't move.

The creature's head started turning. It passed over the closest people, searching for something specific.

It looked past the man crawling beneath an overturned cart, a woman bleeding on the curb, a delivery driver frozen by his open truck. Every single one of them was within its reach.

The gray unnatural creature looked straight at Mara.

Its nostrils opened wider, smelling the air, and the paper cut on Mara's thumb pulsed once. One single drop of blood combined with a drop of rain and fell to the street.

It saw her and found what it wanted.

"Mara!?" Her mother said again.

The creature began to move, crossing the street as one hand struck sparks off of the asphalt. A man clipped Mara's shoulder as he fled. Someone shouted at her to run. Her phone was still in her hand, still connected to her mother on the other end, listening to all of the chaos with no response from her daughter.

Across the street, the man in the black coat looked once at the traffic camera above the intersection. Then at her. For a fraction of a second his face hardened. Even drowning in her own pulse, Mara understood what she was watching.

He was weighing whether saving her was worth being seen, whether he could end this before Lumen arrived, before the cameras turned a rescue into another warning.

He made the choice in less than a second, and the man in the black coat drove off the curb.

Mara saw one step, and then the rest became rain tearing sideways and a black shape crossing the street too fast for her eyes to keep. A hot smear of motion dragged behind him.

Then he was in front of her.

To Mara, he looked like orange lightning cutting through the rain.

For one heartbeat her mind made the only connection it had left: the man in the black coat is impossible too, and I'm in the middle.

Then the blur hit the creature, and the impact detonated between them.

Air slammed into Mara's chest and threw her backward. Her feet left the ground. Her back met the bus shelter and emptied her lungs; glass came down around her knees like rain.

When she looked up, the creature had stopped inches away.

The man stood between them, both hands locked around its wrists, boots carving backward through glass and rainwater.

She caught him in pieces. Short dark hair. A beard. A coat pulled tight across shoulders braced against a force that should have folded him in half. A hard glow pressed beneath the coat at his collarbone and down his forearms, trapped under fabric and skin.

The creature pushed. The man held.

He didn't look back at her.

"Behind the shelter," he said through his teeth. "Stay down."

Then his grip shifted, one wrist down, one across, and his knee came up into the creature's ribs with a sound like a board splitting. The whole gray body left the pavement. He turned with it, fast and controlled, and drove it through the side of a parked car. Both doors caved, and the vehicle shoved half a foot across the street.

That was the first thing Mara understood about him. He fought like a man trying to end a problem before the world noticed.

The creature tore out of the ruined car and came again. He stepped in before it found its balance, caught the swipe at the wrist, and drove his fist under its ribs. The crack of it rang across the intersection. The body hit the street. Asphalt split beneath it.

Relief broke loose for one second.

Then the creature stood up.

Its shoulder twisted back into place. The broken ribs rose and settled under the gray skin. The split in its jaw closed around the next breath.

The man saw it too.

His eyes dropped to the closing ribs, then cut to the creature's feet.

"Okay," he said under his breath. "You heal too fast."

The creature didn't charge him again. It turned toward the shelter, toward Mara, toward the people who had folded behind the bent shelter frame and metal benches.

A delivery driver dragged himself away one-handed, a palm pressed to his thigh. A woman pulled him by the jacket and slipped in the dark spill. The creature's head snapped toward the scrape of shoes across wet pavement, then back to Mara, fixed on her again.

The man got there first.

This time she could almost track him, fast enough that the air cracked when he hit it from the side. They went through the shelter frame together, metal screaming, glass bursting over her shoulders. He caught the creature's wrist a handspan from the fallen woman and twisted until the arm bent backward.

The creature bent it back. Its jaw split wider.

The second exchange changed because this time it learned. It took his hit and gave one back. They crashed through the side of a stopped car, folding the metal like paper, and he came out first only because he'd taken the bad angle on purpose to keep the people behind him alive.

Its claws caught his side as it fell.

He swallowed the sound before it could become a scream. Blood ran down the black coat and engulfed the glow along his forearm.

Mara pressed a hand over her mouth. She had seen people hurt before: in training videos, in the careful diagrams from a fellowship packet she'd had for three days. None of it had readied her for a man trying to keep pain private in the middle of a street full of cameras.

His attention cut from the wound to the creature already rising. The torn skin along his side began to pull closed.

The torn flesh pulled tighter under a deeper pressure Mara couldn’t name.

His eyes left the wound and fixed on the creature.

"They gave you that too," he said under his breath.

The creature lunged. He didn't rush to meet it. He stood still long enough that Mara thought he had missed his chance.

Then pressure gathered around him. At first it sat low and heavy, before any visible light. A low orange pressure tightened across his shoulders and bleeding hand and his fist closed.

Above the light, the traffic camera's red indicator blinked.

He noticed. In that half-second his face went hard and focused.

The creature hit him, and he caught it. The impact drove his boots back through glass and rainwater, but he held. His wound opened wider under the strain, fresh blood running down his side while a faint glow threaded up his forearm.

The creature's broken ribs began to lift again.

This time, he didn’t let them finish.

The first punch folded the creature's guard into its chest and drove the ribs back down before they could set. The next two came before it could lock its knees or finish dragging its shoulder back into place, and sent it through the broken lobby doors into the dark beyond.

The walls inside shuddered. Dust rolled out into the street.

For a few seconds there was only impact: one crash before the previous one had stopped echoing, then another, no space left for the creature inside to find its feet again.

One final crash cut off into silence.

The man came out on one knee. The creature didn't come out at all.

His shoulders rose once, hard, then steadied.

He stayed down, one hand pressed to his side while rain and blood pooled beneath him. He had won. He didn't look like anyone Mara had ever seen win anything.

He looked back into the lobby at the body that hadn't come out.

"I'm sorry," he said, almost too quiet to hear. "They did this to you too."

Mara could only stare.

That was when the sirens finally cut through the shock. Close now. And so were the phones: people edging out from behind cars and benches with cameras raised, filming the man who'd saved them.

Phones, the traffic pole camera, the bank camera, and the drone holding above the intersection.

For the first time since the building screamed, real alarm crossed his face. The cameras put it there.

He pushed to his feet. He swayed once, then steadied. And that was the second thing Mara understood about him: he could be hurt, he could be slowed, and he was still standing between the dark doorway and everyone else.

His eyes found hers through the rain and the wreckage. Dark blue-green, darker than she expected. Sharp, even through the blood.

"Get out of here," he said. "Before they decide you saw too much."

Her throat had gone too small. The question came out before she could stop it.

"What are you?"

His gaze held her for an instant, long enough that she knew he'd heard, but not long enough to answer.

Red and blue swung around the corner and washed over the glass.

He stepped back. "Before they get here."

Then he was gone. One moment he stood bleeding under the billboard; the next, he cut between two buildings before the first cruiser reached the intersection.

Mara stayed behind the cracked shelter with blood on her sleeve that wasn't hers and her mother's dead call in her hand.

Above the wreckage, the billboard still smiled down at the street.

A safer tomorrow. Together.

Six blocks away, beneath a building with no name on its public directory, a screen woke inside a windowless room.

The analyst on duty had been watching three quiet monitors and drinking vending-machine tea that had gone cold an hour ago. Hart Street was supposed to stay quiet. Calder was supposed to stay quiet.

That was why the first alert read like a system error, until the data finished loading underneath it.

Street camera capture. Heat distortion. Impact readings. A blood-trace anomaly.

A single line resolved in white.

ORIGIN SIGNATURE DETECTED — CALDER CITY.

The analyst stopped breathing for a second. Then she reached for the secure line.

"Director," she said. "Hart Street confirmed it. We found him."

A pause. Then a man's voice answered. "Name."

The facial match resolved.

REED MERCY.

The line went quiet long enough for her to hear the ventilation overhead.

When the voice returned, it was almost gentle.

"Lock down the city. Immediately."
