Chapter 4: Shared Liability

Callum lasted four minutes before calling Mara Ortega.

She answered on the second ring. "How dead?"

"Me or the problem?"

"Either."

"Currently ambulatory."

"Then the problem."

He looked at the ghost under the paper shop awning. She had folded her arms while he walked the edge of the tether with a laser rangefinder. The root marks returned at two hundred and eighty-seven feet and became medically discouraging at three hundred and six.

"Complicated," he said.

"I'll bring the large case."

Mara arrived eighteen minutes later in a gray hatchback with a dented passenger door, parked across a garage entrance, and found Callum standing beside his van with a dead woman ten feet away.

Her eyes stopped on the ghost.

"You called this complicated."

"I was conserving detail."

"You were conserving syllables."

She was short and solidly built and dressed for a crawl space: work pants, steel-toed boots, hair twisted up under a canvas cap. A silver chain disappeared into her black thermal layer. She popped the hatch on three hard cases and did not look away from the ghost while she did it.

"You brought a colleague," the ghost said.

"Former colleague," Mara said.

They had been partners for three years. The split had produced two tool inventories and one disputed invoice. Mara destroyed what she judged dangerous. Callum preferred removal, containment, and the comforting fiction that those were morally neutral.

"Where's the active site?"

"Second floor. Basement stays sealed."

"Who decided that?"

"The contractor."

"Good. Contractors are cowards with excellent survival rates."

She took the largest case. Callum took the other two. The dead woman followed them inside without being asked, which saved an argument none of them would have won.

The vestibule smelled of wet plaster and overheated wiring. Emergency lights washed the stairs in weak amber. Mara stopped on the first landing and rolled her chain once between two fingers.

"You used Declan's paper."

Callum kept climbing. "Part of it. The hairpin was the anchor."

"You'll show me the arrangement."

"I'll show you."

"That's what surgeons say before you wake up missing an organ."

"He does inspire confidence," the dead woman said.

Mara glanced back. "You can speak when spoken to."

"You may wait a century for the invitation."

"That can be arranged."

Their dislike had the clean fit of matched blades.

On the second-floor landing, Callum caught movement in the dark glass of a framed print.

The dead waiter stood behind them. His white jacket was stained down one side now, and roots showed under his throat. In the glass he carried an empty silver tray and watched the ghost with hollow concentration.

Callum turned. The landing held Mara, the ghost, and three abandoned floral arrangements. No waiter.

"What?" Mara asked.

He looked back at the print. The waiter was still there.

"Someone in the glass. Young. Catering jacket. Silver tray. Roots at the neck."

The dead woman turned to the print, and her mouth thinned.

"You saw him before tonight?" Mara said.

"No."

The waiter turned his head toward Callum. No blur, no cold patch, no shape explained by bad silvering. Callum could see the seam at the man's shoulder and a brown crescent under one thumbnail. Then the reflected waiter walked through the wall.

Callum gripped the case handle until its molded edge hurt his palm.

Mara watched him instead of the glass. "Any others?"

"Give the evening time."

The ghost passed him on the stairs, and heat left him with her like blood leaving a vein. "Your complaint was that you could not see us," she said.

"I had no complaint."

"You built a trap."

"I had a work order."

Inside, the staged apartment had the sodden exhaustion of a room after firefighters leave. The white chairs stood on towels. Decorative lemons floated in the bowl under the split pipe. Someone had shut off power to the floor, and the bay windows let in gray street light.

Mara set her cases on the driest patch of parquet and worked without wasted movement. Thermal camera, pulse oximeter, adhesive leads, a modified galvanometer, two smoked-glass tiles wrapped in wool, copper mesh. The third case held a bolt cutter.

The woman by the mantel eyed it. "For diagnosis?"

"Some conditions resist treatment."

"Yours appears advanced."

Mara pointed at the center of the room. "Stand there."

She did not move. Callum said, "Qian," and her head turned.

He had found the flyer among Declan's papers, folded around a photocopied burial map. A Chinatown ghost tour advertised NIE XIAOQIAN, THE GHOST GIRL OF WAVERLY PLACE, LIKE THE MOVIE. Declan had circled the name and written: Ask what she calls herself.

Contempt sharpened her face. "Do not call me that."

"So you recognize it."

"I recognize graffiti. I do not answer to it."

Mara looked between them. "Useful."

"It offended her," Callum said.

"That was the useful part."

She fixed the adhesive leads under his shirt and clipped the oximeter to his finger. His pulse ran fast but regular. His temperature had fallen to ninety-six degrees. Then she raised the thermal camera toward the ghost, and on its screen the woman's outline burned in bands of orange and yellow. The brightest point sat behind her sternum. A thread of the same color ran from there to Callum, visible only when Mara adjusted the contrast.

"Come closer," Mara said.

She stayed where she was. Callum's temperature dropped another tenth.

"You're drawing from him."

"I am aware."

"Can you stop?"

"If I knew how, I would be farther away."

"Answer the question."

"I did."

Mara took that without apology. She set one smoked-glass tile under the hairpin and the other against Callum's chest, ran copper mesh between them across the floor, and lit a beeswax candle at each corner. The flames leaned toward Callum. When the ghost stepped nearer, half of them leaned toward her.

"That's new?" he asked.

"That's rude."

She relit the last candle after it guttered. Its flame divided at the tip, two small flames on one wick. On the blackened glass under the hairpin, two pale marks had appeared in the soot. One curved toward her. The other ended at Callum's knee.

"What?" he asked.

Mara sat back on her heels. "Double anchor."

"Define it."

"Your rite attached her to the hairpin. Her counter-rite diverted another claim through you. Both closed at once."

The bruises under Callum's shirt cinched as if they had heard her.

"Can you sever it?"

"Probably."

"And?"

"I could destroy her." Mara said it like a test result. "The anchor would collapse through whatever living structure is carrying the other half."

"Me."

"Yes."

"Odds?"

"Bad enough that I wouldn't call it a risk. I'd call it a probable outcome."

Callum took off the oximeter. The clip had left his finger numb.

"So killing her kills me."

"Very probably."

She stood beside the ruined mantel with her hands loose at her sides and did not look at him. "You sound disappointed."

"I dislike shared billing."

"Try shared execution."

Mara closed the first case. "If she's the one who killed Declan, this doesn't make her safe."

"I know."

"Do you?"

"One dangerous ghost dead," Mara said, "beats dozens of living people at risk."

"You have practiced that sentence," the dead woman said.

"I've buried the reasons for it."

A floorboard creaked in the hall.

An old man stood on the landing, visible through the narrow gap in the door. He wore a brown cardigan buttoned wrong and held a paper grocery bag against his chest. Green onions stuck out of the top. Water dripped from one slipper, though the stairs were dry.

He eyed Mara's copper mesh and the bolt cutter, shook his head, and continued upward. His feet made no sound.

Callum followed him to the doorway. On the next landing the man walked through the locked door of 4A, and Callum glimpsed the kitchen beyond: yellow cabinets, a calendar from 1989, steam on the windows. Then the present door came back.

She had come up behind him. "He has been here longer than the cabinets," she said. "Less long than the rent dispute."

"Why can I see him?"

She looked at the empty landing. "You opened something."

Mara latched the last case. Callum went down slowly. In the vestibule mirror the dead waiter waited with his tray and offered nothing. Across Waverly Place, high in a dark bay window, a child's shape pressed both hands to the glass.

The apartment behind the child had no lights and no curtains. Callum knew from the preview documents that the unit was vacant.

Three dead in one building, or close enough to belong to it. None of them appeared in his inspection notes. None had thrown furniture, flooded a floor, or frightened a buyer into calling his company. They had simply remained. He had spent six years making houses quiet and had mistaken silence for vacancy.

Mara joined him at the front door. "Your sight may settle when the tether does."

"And if it doesn't?"

"Raise your rates."

She had looked across the street and seen the child, too. Whatever that cost her, it stayed in her hands, which rolled the silver chain once between two fingers and let it go.

She gave him a narrow canvas roll. Inside lay four iron spikes, a spool of copper wire, chalk, and a folding knife.

"Those won't break the tether. They might keep another claim from fastening to it."

"Might?"

"You used the reliable equipment backward."

Behind them the dead woman came down the last stair. The waiter slid out of the mirror before she crossed it.

Mara faced her. "If you hurt anyone, I come back."

"Your concern for him is touching."

"This isn't about him. If you feed from tenants, open a path, or put a living person at risk, I'll end you anyway," Mara said, "and take what it costs him. He knows I will."

Callum did know. Mara had once ended a haunting while he was still discussing containment with the building owner. A tenant had spent six weeks in traction. Mara had never apologized, and Callum had never proved her wrong.

"Then we understand each other," she said.

"No." Mara shut her hatchback door. "We understand the stakes. Check your temperature every hour. Lose another degree, wake up."

"How?"

"Set an alarm. Your phone remains outside the occult order."

She drove away.

By one thirty, Waverly Place had emptied. Callum parked the van under the paper shop windows, twenty-two feet from the building entrance and well inside the measured boundary.

The ghost refused the cargo area.

"It smells of salt and wet dog."

"I don't own a dog."

"Then you have a more serious problem."

He took the narrow bunk behind the driver's seat. She sat on the hood, visible through the windshield, one knee raised under the dark folds of her dress. Across the street the child had come back to the bay window and pressed both hands flat to the glass.

Callum took his temperature once more before lying back. Ninety-six flat. He set alarms for two thirty, three thirty, and four thirty. He put the hairpin in a steel evidence box under his head. It stayed warm through the lid.

Through the windshield, the ghost had turned toward the vacant window. She lifted two fingers from her knee, the small flat greeting one neighbor gives another across a street, and the child's hands stayed where they were.
