Chapter 7: Isolde

The light switch confounded him for eleven minutes.

Mira did not time it deliberately. She was at the long worktable with her laptop open, pulling what she could from the Archivio di Stato's digitized records — marriage registers, property transfers, the thin paper trail of a woman dead four centuries — when she heard the soft click from across the room. Then silence. Then the click again. She looked up.

Kael stood at the wall beside the eastern window, one finger pressed flat against the switch. He was watching the ceiling fixture. Click. Light. Click. Dark. His expression was the same one he'd worn when he'd pressed his palm to the window glass that morning and gone still for a long time, reading the cold through the pane with his whole hand, not just his fingertips.

"It's electricity," she said. "Controlled current. It runs through the walls."

"Through the walls." He pressed the switch one more time, held the light on, and turned to look at her. "All walls?"

"Most buildings, yes."

He looked back at the ceiling as if recalibrating something. Then he released the switch and moved on, drawn toward the canal-side window by the sound of a water taxi throttling under the bridge. He watched it pass with the same absolute attention he gave the light switch, the same patience, the same quality of a person examining phenomena rather than experiencing them. She watched him from the corner of her eye and had no word for what it produced.

He had spent the morning like that — moving through the rooms she'd granted him access to, touching walls, surfaces, glass panes, the iron railing of the mezzanine, the radiator cover, the underside of a marble sill. He touched everything that was still, and watched everything that moved, and asked no questions except the ones he meant seriously. There had been seventeen questions by eleven o'clock. She had answered all of them.

She turned back to the records.

Isolde Maren, née Caretti. Born Venice, 1609. Married Domenico Maren, 1635. No children registered. The church records used the word pittrice — female painter — which in 1635 was either a compliment or a category, and the document didn't specify which. The guild registers were less complete than she'd hoped; the years 1639 and 1640 had gaps, pages lost to water damage or simple attrition. The Maren family household accounts, which someone had digitized imperfectly in 2009, showed recurring payments to an unnamed supplier of pigments and preparation materials, running through December 1640.

From the window, Kael said: "The sound is different."

"The city?"

"The water. It moves differently than I remember. Louder in certain registers."

"The boats. Engine-powered."

"The engines are below the waterline?"

"The hull sits in the water. The propeller drives the boat forward from beneath." She glanced over. He had pressed his forehead against the glass — lightly, in the manner of someone testing whether the cold of it was real. "It looks strange from above but it works."

"Most things that work look strange from the angle you don't expect." He straightened from the window, and she turned back to her screen before he could catch her watching him.

She found the death record at half past three.

Isolde Maren. Died 14 March, 1641. Fever. Buried in the church of Santa Maria Formosa, which was four bridges from the palazzo. The register noted lavori straordinari completati — extraordinary works completed — in the week prior. No elaboration. The word straordinari might have meant technically difficult, or consuming, or remarkable in the execution; the clerk who wrote it was four hundred years dead and could not specify which meaning he intended.

Mira sat back.

Completed the works. Died within a week.

She opened a second window on her laptop, cross-referenced the palazzo's own property records: the fresco commission dated to the winter of 1640, the completion noted in the spring correspondence. She had the exact date from her own plasterwork analysis — the seal's chemical composition, the drying rate, the specific material characteristics of the plaster layer applied over the fresco — and she'd placed the sealing in the second week of March 1641. Three days before the death record.

She wrote in her field notes, in the small precise hand that fifteen years of conservation work had made automatic: Fresco sealed: approx. 11 March 1641. Isolde Maren death: 14 March 1641.

She stared at it for a moment.

Her phone buzzed. Fenya, video.

She answered before she thought about whether she should. Fenya's face appeared on the screen — close-cropped hair, reading glasses pushed up to her forehead, the yellow kitchen wall of her Bermondsey flat visible behind her. Outside Fenya's window, London rain moved against the glass in the particular grey British way.

"You look like someone handed you a problem you can't put down," Fenya said by way of greeting.

"Good evening to you too."

"It's evening there? Mira, you've been in that building all day."

"The archives are online. I've been doing research."

"Into the fresco."

"Into the painter. There are gaps in the record I need to account for."

Fenya tilted her head. There was a precision to her silences — she was a materials conservator by training and a diagnostician by long habit, and her silences had the quality of her instruments: they measured what they rested on. "You sound strange," she said. "You sound like someone is listening."

"No one's listening." She kept her gaze on the screen. From the corner of her vision she could see Kael at the secondary worktable, turned deliberately toward the window, giving her the privacy of his attention pointed elsewhere. She had noticed that he did this — turned away during her phone calls with the deliberateness of someone who understood the concept of privacy even if proximity made it technical. "It's a sensitive project."

"All your projects are sensitive."

"This one more than usual. The family has particular concerns about the material."

Fenya studied her through the screen with the expression she used for objects she wasn't certain she was reading correctly. "Is it the figure? You said the main figure was extraordinary."

"Yes. That's the word for it."

"The restoration is going well, though?"

"Better than expected. I'm finding things I didn't anticipate." She looked at her field notes. "That's the issue. I'm finding things."

They talked for another ten minutes about things that weren't the fresco — a mutual friend's show in Edinburgh, the delayed shipment of consolidant that was holding up Fenya's current job in Siena, whether Mira had eaten a real meal. She said yes. She had eaten bread and something from a jar Raffaele had left on the counter at noon, which was plausibly a meal.

When the call ended, the room felt different than it had before, in the way rooms do after a window closes — a subtle pressure shift.

Kael hadn't moved. He was watching the canal window, where the afternoon light had gone amber, the water cutting the last of the sun into moving pieces on the wall. His hands were flat on the table in front of him, perfectly still. There was something in the set of his shoulders she couldn't read clearly yet — not tension, but a held quality, like a word in the process of being decided against.

She looked at her field notes.

Fresco sealed: approx. 11 March 1641. Isolde Maren death: 14 March 1641.

She picked up her pen. She looked at the dates and thought about what they implied — the proximity, the specificity, the fact that Isolde Maren had begun a commission no other painter in Venice had apparently known about and died four days after its completion, young by the standard of her era, with no illness recorded before March of that year.

She wrote one more line beneath it, in her small precise hand:

Died in circumstances no historical record explains.

She stared at what she'd written. Outside, a bell began to count the hours — one of the old parish bells, its bronze voice carrying over the water the way it had carried for centuries, indifferent to everything that had happened beneath it. The lamp on the worktable cast its steady pool of light. Across the room, the fresco waited in its half-uncovered state, the painted king's face turned toward her from across four hundred years, and the line she had written waited on the page for an answer she did not yet have.
