Read Chapter 20: The Debt Collector

The knock came at seven in the morning, too sharp, too deliberate. Eliza was already awake, sitting at her mother's kitchen table with the owl ring turning between her fingers, the 1994 letter spread before her like a wound she couldn't stop picking at.

She opened the door to Detective Inspector Marsh, who she'd last seen at Marcus's inquest, and two uniformed officers behind him. Marsh's face was a careful blank, the kind worn by men delivering news they already know will destroy someone.

"Dr. Hart. I need you to come with me."

"What's happened?"

"Professor Whitmore was found dead in his college rooms an hour ago." Marsh paused, watching her reaction with the patience of a man who'd learned to read people in the space between their words. "The manner of death is consistent with Professor Vance's."

The floor tilted. Eliza gripped the doorframe. Whitmore. The man she'd confronted barely a week ago, who'd admitted knowing about the society's role in her father's investigation, who'd warned her about Wren and the anonymous donor. Dead. Same poison. The untraceable one from the Codex—the one her father had made.

"Consistent," she repeated. "You mean the same poison."

"We mean the same method." Marsh's eyes didn't leave her face. "There's something else. The body was arranged. Professional. Hands folded over the chest. A symbol drawn on the wall above him in what looks like lampblack."

"What symbol?"

Marsh pulled a photograph from his coat. A silver-green eye, stylized, almost serpentine. Not the Archai's owl. Something older. Something she'd seen in the crypt's marginalia, sketched in the margins of the ledger beside her mother's name.

The owl's sight. The debt collector's mark.

"I don't know what it means," she said, which was almost true.

"That's not why I'm here, Dr. Hart." Marsh stepped forward, and the uniforms moved with him. "We have a witness. The college porter saw a woman matching your description leaving Whitmore's rooms at approximately two in the morning. Whitmore's notes mention a scheduled meeting with you regarding a manuscript."

The air left her lungs. "I was here. Alone. All night. I didn't—"

"Can anyone corroborate that?"

Julian. But Julian was the last person she could invoke. The police would find his calls to Wren, his ledger entries, his entire architecture of half-truths and hidden alliances. Bringing him into this would bury them both.

"No," she said. "No one."

The interrogation room at St Aldate's Police Station smelled of stale coffee and recycled anxiety. Marsh sat opposite her, a manila folder closed on the table between them. She'd refused a solicitor, which she suspected he took as either arrogance or guilt. It was neither. She simply couldn't afford the delay.

"The symbol," Marsh said. "Think harder. Does it mean anything to you?"

"I'm a classicist, not an epigrapher. There are dozens of obscure symbols in the Roman magical tradition—"

"Whitmore was poisoned with a compound we can't identify. The same compound that killed Professor Vance, a man whose death you were also intimately connected to. And now the only other person who knew about the Codex of Nero is dead, and a witness places you at the scene." Marsh leaned forward. "That's not a pattern, Dr. Hart. That's a thread."

"The thread goes through the Archai," she said. "But I didn't pull it."

Marsh's expression didn't shift. "The Archai. The secret society you claimed was responsible for your father's death."

"It is responsible."

"And yet Whitmore—a member of the Archai, by your account—was murdered by the same method used to kill the man who was investigating them. If the Archai wanted Whitmore dead, why use the same poison that would immediately implicate you?"

She had no answer for that. Because it wasn't the Archai. Not Wren's faction, at least. The masked figures who'd taken the Codex were a rival element, seeking its destruction. And now someone had used the poison—her father's poison—to kill Whitmore and leave a debt-collector's mark above his body.

The pieces shifted, reformed, and clicked into a shape she didn't want to see.

Her mother. Standing at the crypt entrance decades ago. Her mother, an initiate. Her mother, who owed a life-debt.

Her mother, who was alive and in London and had never once asked where Eliza had been going these past weeks.

"Do you know who Rowena Ashworth was?" she asked.

Marsh's eyes flickered. "An antiquities dealer. Died in 1994. Car accident. Why?"

"Because I think Whitmore's death is connected to hers. I think someone is collecting a debt that's been owed for thirty years, and the Codex is collateral."

Marsh opened the folder. Inside, a second photograph. Whitmore's rooms, taken before the body was moved. A desk covered in papers, and among them, clearly visible, a page in familiar handwriting—her father's handwriting, the flowing script she'd grown up reading in letters her mother said were from a mentor.

"What is that?" she asked, though she knew.

"Correspondence. We found it in Whitmore's rooms. A letter from your father, dated twelve days before his death." Marsh slid the photograph closer. "In it, your father tells Whitmore that he's found a way to break the debt. That he's going to use the Codex to do it. And that if anything happens to him, Whitmore is to destroy the Codex and protect you."

Her father had known. He'd known about the debt, about the Archai, about everything. And he'd written to Whitmore not as a conspirator but as a guardian.

"He knew Whitmore," she said slowly. "He trusted him."

"Did you?"

No. She'd trusted no one. She'd confronted Whitmore like an enemy, accused him, pressed him. And now he was dead, killed in the same way as Marcus, the same way her father—the letter was wrong about one thing. Her father hadn't died in an accident. He'd been arranged. Wren had said so. Arranged by someone who never met him.

The debt collector.

She looked up at Marsh. "I need my phone call. Now."

"Who are you calling?"

"The one person who might still have the answers. The woman who owes the debt."

Marsh frowned. "Your mother."

"No." Eliza stood. "The woman who married my father after 1994. The woman who was there when the debt was made. My mother—my real mother's debt—belongs to the Archai. But the woman I call mother isn't the one who owes it."

The realization landed like a physical blow. The photograph in Julian's ledger. The woman at the crypt entrance. The 1994 letter demanding payment.

Her mother's first husband, the initiate who disappeared.

Her mother, who married her father—Whitmore's student, Whitmore's colleague—three years later.

The debt had been her mother's. But the blood was her father's.

And the Codex, the poison, the letter Whitmore had hidden—it was all one thing.

Her father had made the poison out of love for her. And someone had used it to kill the man trying to protect her because she'd come too close to the truth.

"Dr. Hart," Marsh said. "You need to sit down."

"Tell me one thing," she said, her voice steady despite the racing in her chest. "Was Whitmore's body found with a ring? A gold ring, shaped like an owl?"

Marsh's silence was her answer.

"The ring is mine," she said. "And I can prove who put it there."

She reached into her pocket, pulled out the gold owl ring Julian had found in her mother's house, and set it on the table between them.
