Chapter 1: A Join Before Dawn

The pear scion resisted by less than the width of a thread. Barbara held it between finger and thumb against the cut Theo had prepared in the rootstock. Frost whitened the brick coping of the South Espalier Wall, and the cold found the pale scar across her left wrist where it steadied the young wood. The rest of the garden lay in the grey before sunrise. Here, close to the wall, every fault had a shape.

Theo March watched her hands. He had cut the stock cleanly and offered her the scion without telling her which side would fit. That was why she had agreed to come before breakfast. She had no use for work invented to occupy a newcomer, and still less for praise given in advance.

"The green has to meet," he said. "One edge is enough if it's a true edge. Two would be luck."

Barbara turned the scion a fraction. Beneath the brown skin, the cambium showed as a fine wet line. The cut faces met. One side lay flush; the other stood proud. She shifted it back until the living layers touched from shoulder to point. Theo handed her a roll of bright Blue Binding Tape.

"Which way?" he asked.

She looked at the slant of the join and at her own grip. "Rightward. If I wind against my pull, the first turn will loosen while I make the second," she said.

"Then rightward."

She anchored the tape below the cut and drew it round. It stretched clear where the strain thinned it, blue where each turn overlapped the last. Her right hand kept the pressure even; her left held the two pieces in one line. On the final turn she pulled the tape across itself and severed it with the small blade Theo had laid on the coping. The tail drew tight and lay flat. She pressed the union once with her thumb, then took her hand away and tested the scion with one light sideways touch. It held.

Theo tested nothing after her. He bent until his face was level with the join, looked along both edges, and put the knife back beside his canvas Grafting Roll. "Sound," he said. "This teaching set held three prepared scions. You have finished the first; the other two stay wrapped here for Borrowed Branch Day. We'll take the binding off in four weeks."

"I said I would do one."

"And you have." He wrote her name and the time on the label. No coaxing followed. He had let the work stand; in the cold, that was courtesy enough.

The first stroke of the Frost Bell came from beyond the wall. Its rope struck stone between blows, a hard double sound: bronze, stone, bronze. Theo straightened. A second peal drove rooks from the bare limes by Delmere Court.

"Severe frost watch," he said. He closed the Grafting Roll, then frowned at its empty place on the coping. "No. I left the full roll by the pump house. This is the teaching set. Come on."

They entered Frost Bell Courtyard with the light still low and the bell shaking the paving underfoot. White frost cloth poured from baskets, crossed shoulders, caught on chair wheels and walking frames, and turned the residents beneath it into moving shapes. Kettles hissed under the arcade. Someone had brought three blankets and no gloves. Nicholas Bryant, wearing a bright knitted tie under his work coat, carried a copper kettle against his chest and announced to nobody visible that the boiling-water division had arrived without boiling water.

Kelly Davis stood beside the bell rope in a green waterproof coat, assigning places faster than some people could reach them. "Samuel, north tubs and photographs. Nicholas, warm water to the wall beds, never hot. Mrs Paxton, stay where your chair has brakes. Theo, South Wall. Barbara Liu, you are with him."

"I can hear you through cloth, Kelly," Barbara said.

"Excellent. Then the system works."

A length of white cloth dragged across the wet bricks in front of Barbara. She caught its hem on the crook of her folding cane and lifted it clear while two residents passed beneath. Theo took the far end, not from her hand but from the paving beyond it, and together they drew the cloth over a row of tubs. Under the cover, blossom buds made small dark points against the white. The warmth from the kettles smelt of metal and damp wool.

"Why all the carrying?" Barbara asked. "Those tubs could live nearer the wall."

"That plum belongs to the woman in number twelve," Theo said, nodding at a labelled branch above somebody else's rootstock. "The roots belong to number nine. The old pears are spread wider. No household owns a whole rare tree here. Lose one host in a frost and you may lose three people's fruit."

It wasn't a welcome speech. He was explaining why the heavy tub had to move, and then he moved it with Nicholas while Barbara held the cloth high enough for their feet. Around them, dependence looked less like kindness than a list of awkward jobs done before breakfast. She could respect a thing that showed its seams.

Theo set down his end. "My Grafting Roll's still at the Disused Pump House. I need it before somebody uses the clean knife on ties. I'll be back in five minutes. Keep this corner off the wet."

He went through the arch toward the service path. Barbara watched only until his boots cleared the loose gravel, then hooked the cloth over the final peg. Kelly sent her to the courtyard edge where a cover had bellied with cold air. Samuel Smith tilted his camera toward the whitening buds and waited for the cloth to settle before he took each picture. Behind him, Theo's station remained open.

Five minutes passed. Then seven. The bell stopped, leaving the courtyard full of smaller sounds: cane tips, wheels, the click of kettle lids, water striking terracotta. Barbara asked Nicholas whether Theo had returned by the west arch. Nicholas lowered his kettle and gave her a plain no.

Brent Smith MD came out from Delmere Court in shirtsleeves and a formal waistcoat, one pair of glasses on his face and another in his pocket. "Please remain at your stations. The paths are slick, and we need a count before anyone moves elsewhere."

Barbara planted the last peg. "Count me on the South Wall path."

"Mrs Liu, I am asking everyone to stay in the courtyard."

"Then ask Theo to come back."

Brent looked toward the empty station. That pause was permission enough. Barbara folded her cane out to its full length and crossed under the arch. White covers narrowed the paths and hid the lower garden. Twice she had to lift a hanging edge before she could see where the wet bricks changed level. The rubber foot of her cane slipped into a mortar joint and caught. She freed it without haste. Haste spent balance and bought little.

Theo's brown cap lay crown-down beyond the turn to the pump house. Frost had begun to gather on its brim. The service path continued left, but one dark scrape marked the bricks toward the South Espalier Wall. Barbara called his name. The cloth behind her rose and fell in the wind. Nothing answered from the wall.

The ladder had fallen sideways beneath the espalier pears. Theo lay under its upper half, his face turned from her, one arm across the cold paving. His coat had ridden up at the shoulder. There was no movement in the cloth at his back. Barbara stopped outside the scatter of tools and looked at the ground before she chose where to set her cane. She went no closer than his outstretched hand. The skin at his neck had the settled colour of wax kept in a cold room. Two fingers against it told her only what she needed to know.

"Brent!" Her voice carried along the brick. "Send Dr Smith. Keep everyone else back."

She remained on one knee, clear of Theo and the ladder. The paving pressed cold through her trousers. To her right, above the fallen man's shoulder, a strip of blue caught against the grey wall. A pear scion stood newly bound to a prepared stock. The tape gleamed wet.

Brent arrived first, breathing through his open mouth, with Kelly behind him and Samuel several paces farther back. Brent crouched beside Theo, touched him at neck and wrist, and removed his glasses. He looked at the ladder, the coping, the tools.

"It appears he's fallen," he said. "Kelly, clear the orchard. Nobody touches anything. Samuel, put the camera away."

Kelly took in Theo, then the residents gathering as pale forms beyond the cloth. Her face held still. "Back to the courtyard, please. Take the west arch. Nicholas, turn them before they reach the path."

Brent reached toward a pair of secateurs lying near his shoe, meaning to clear a place to stand.

"Leave those," Barbara said.

His hand stopped. "I need room to examine him."

"Then move yourself. The tools stay. And that graft stays."

Kelly looked up at the blue binding. "Theo's?"

"No." Barbara rose with the help of her cane. Her knee objected, then bore her. She pointed to the union without crossing the clean paving between them. "The tape overlaps to the left. Look at the ridges. The maker pulled from that side and lost pressure at every return. The tail has been pressed down and cut blunt. Theo drew his bindings rightward. So do I. We finished one together before the bell."

Brent's eyes went from the graft to the ladder. "That doesn't alter what happened here."

"It alters what may be thrown away."

Samuel had kept the camera. He stood where Barbara had stopped and tilted the lens toward the union. "May I photograph from here?"

"Yes," Brent said after a moment. "Only from there."

The shutter made a small dry sound. Samuel changed his angle by one step and took another image. He counted on two gloved fingers before lowering the camera. "I can record how it looks now. I can't give you an exact minute from a changing join."

"I don't require one," Barbara said. She could still see the morning's other graft: the clear stretched tape, the flat tail, Theo's face level with her work. This stock had stood bare when they left the wall. She had used the first of the teaching set's three prepared scions; the other two remained wrapped at Theo's open station. The scion on this stock came from another source. Theo had gone for his roll during a frost alarm, with sound work behind him and no cause to bind another union badly. Those were observations. The order they made was an inference, but it was an inference with edges.

Kelly's grey-green gaze settled on Barbara. "Are you certain enough to delay clearing this wall?"

"I am certain that Theo didn't make that binding. I am certain it wasn't there when we left. I infer that whoever brought him here made it after he was dead, to make the ladder and the tools tell one story. You may disagree with the inference. You may not destroy the graft."

For several seconds, only the covered branches moved. Brent put his glasses back on. The professional arrangement returned to his face, but he stepped away from the secateurs.

"The orchard is closed pending official inspection," he said. "Every path, tool and work station. Nobody removes anything."

"The exposed scion is already changing," Barbara said. "Cold will slow it. Dry air will kill it. If you leave the whole union here, inspection will preserve a dead object and lose the living one."

A green helmet appeared beyond Kelly's shoulder. Vanessa Chase ducked under the last hanging cloth, took one look at Theo, and stopped. Her hands went to the buckles at her belt without touching them.

"Tell me what you want cut," she said.

Barbara pointed. "The scion above the union, with enough of the cut face to keep the binding as it is. Can it come away without disturbing the stock?"

Vanessa looked upward, then traced an angle in the air. "Yes. Cut here, a hand above the top turn. Support before the blade closes. Don't touch the union." She looked at Brent. "If it stays exposed, you lose condition. Removal is the safer preservation."

Brent pressed his lips together. "Photographs first. The cut is witnessed. It goes into sealed, cool custody, and this isn't my endorsement of a murder theory."

"Nor mine," Samuel said. "I have differences, not a time of death."

Barbara took a clean folding knife from the deep pocket of her altered work jacket and offered it to Vanessa for inspection. Vanessa asked permission before taking it, opened the blade, and sighted along the edge. She handed it back. Samuel photographed the proposed cut point, the knife, and Barbara's empty hand. Kelly stated the time from her watch.

Barbara drew a square of linen from another pocket. It had wrapped her morning flask and was still cool. Nicholas brought water in a clean enamel cup and set it down without crossing Samuel's chosen line. She dampened the cloth, wrung it once, and laid it open on the paving beyond the scatter. Then she supported the scion where Vanessa had shown her and made one clean cut. The young wood came free. Its blue binding remained untouched around the lower join.

Samuel photographed it before Barbara folded the damp linen over it. Kelly repeated the time, and Samuel wrote it down. The moisture darkened the cloth against the front of Barbara's work jacket. Detached wood remained usable for no more than seventy-two hours when kept cool and damp. She said the words aloud so Brent, Samuel and Kelly could each hear the limit.

Brent turned toward the white-covered path. "Take it to the courtyard. No other material leaves this wall. I am recording the death as an apparent ladder fall until the proper authorities examine the scene."

Barbara slid the wrapped scion into her deepest pocket, where the cloth would stay shaded. She made no claim about whose hand had bound it. Behind her, Theo lay beneath the false order of ladder, wall and tools. Ahead, the Frost Bell Courtyard waited under white cloth, full of people being sent indoors. With each measured strike of her cane on the wet brick, the blue end of the binding rose once from her pocket and disappeared again.
