Read Chapter 15: The Emperor's Poison

The Bodleian’s lower reading room smelled of dust and old leather, the kind of air that felt centuries thick. Eliza had bribed a junior librarian with a bottle of sherry and a convincing lie about a research grant, and now she sat in the west alcove with the Codex of Nero open before her, its pages guarded by a chain that felt ceremonial at best.

She had expected something grander. A dark tome bound in human skin, perhaps, or pages inked with warnings. Instead, the codex was small, almost unassuming—a tenth-century compilation of imperial gossip, court intrigues, and remedies. Remedies. That was the euphemism the catalogues used. Eliza had spent three hours cross-referencing Marcus’s marginalia against the manuscript’s folios, and her hands were shaking.

The passage was on folio 47v, tucked between a treatise on oratory and a recipe for a digestive tonic. Marcus’s pencil marks were faint but unmistakable—a thin, trembling line beneath three lines of Latin describing a compound of aconite, hemlock, and something the scribe called *sanguis imperatoris*. Emperor’s blood. Eliza’s Latin was better than most, but the term made no sense. She checked the glossary. *Sanguis imperatoris*: a rare fungus said to grow only in the ruins of Nero’s Golden House, harvested at the new moon, dried, and ground to a powder so fine it dissolved without trace.

Untraceable. That was the word Marcus had written in the margin, twice, underlined.

Eliza sat back. Her pulse hammered in her ears. Fifteen years ago, her father had died of a heart attack at fifty-two, healthy as an ox. The coroner had ruled it natural causes. Her mother had never questioned it, not publicly. But Eliza remembered the way her father had flinched at dinner parties when anyone mentioned the Classics faculty at Oxford, the way he’d changed the subject whenever Marcus Whitmore’s name came up. She had been twelve. She had thought it was just academic rivalry.

Now she understood it was something else entirely.

She photographed the folio with her phone, then carefully closed the codex and returned it to the reading room desk. The librarian barely looked up. Eliza’s lies were getting better. That should have frightened her more than it did.

Whitmore’s office was on the second floor of the Ashmolean’s north wing, a corner room with windows that caught the late afternoon light. His door was ajar. Through the gap, Eliza could see him at his desk, head bowed over a stack of papers, fountain pen moving in slow, deliberate strokes. He looked older than she remembered—grayer, thinner, the skin around his jaw slack. But his eyes, when he finally looked up and saw her, were sharp as ever.

“Eliza.” He set down his pen. “I wasn’t expecting you. I thought the council had—well.” He gestured vaguely. “Given your recent… difficulties.”

“They haven’t expelled me yet.” Eliza stepped inside and closed the door behind her. “May I sit?”

Whitmore hesitated, then nodded. She took the chair across from his desk, the same chair she’d sat in as a nervous first-year, asking about Roman elegy and trying not to sound as intimidated as she felt. The irony was not lost on her.

“I’ve been reading about poison,” she said.

Whitmore’s pen hand stilled. His face did not change—it was a mask he had perfected over forty years in academia—but his fingers curled slightly around the pen. “That’s an unusual topic for a classicist.”

“I found a codex. The Codex of Nero.” She watched him carefully. “Marcus was studying it before he died. He had notes in the margins. A recipe for something allegedly untraceable. *Sanguis imperatoris*.”

Whitmore said nothing. The silence stretched. In the corridor, a group of students laughed, their voices muffled and distant.

“My father,” Eliza said, “died of a heart attack when I was twelve. He was healthy. He ran every morning. He had a checkup three months before. The coroner said natural causes.” She paused. “My father knew you, didn’t he?”

Whitmore’s jaw tightened. For a long moment, he looked at her, and Eliza saw something flicker behind his eyes—not guilt, exactly. Regret, perhaps. Or calculation.

“Your father,” he said slowly, “was a brilliant man. One of the finest minds I ever taught. He made a mistake. We all make mistakes.”

“What kind of mistake?”

“He asked the wrong questions.” Whitmore leaned back in his chair. “The Archai are not a debating society, Eliza. They are a covenant. A covenant requires trust. Your father began to suspect that some of the society’s earliest families had—how shall I put it?—purchased their positions. That information was not meant to be uncovered. He approached me, because I was his advisor. He wanted me to help him expose it.”

Eliza’s heart was beating so hard she could feel it in her throat. “What did you do?”

“I advised him to drop it. He refused. He went to the Bodleian the next week to examine the founding charter.” Whitmore’s voice dropped. “He never came home.”

“The charter was stolen,” Eliza said. “The night my father died.”

“Yes.”

“And you knew about that.”

Whitmore’s silence was answer enough.

“Why didn’t you tell anyone?” Eliza’s voice cracked. “You were his advisor. He trusted you.”

“I owed Marcus a favor.” Whitmore’s eyes met hers, and for the first time, she saw something like shame there. “Years ago, Marcus did something for me. Something that saved my career. Perhaps my life. When your father’s investigation threatened to resurface, Marcus asked me to keep quiet. He said he would handle it. I believed him.”

“And did he? Handle it?”

“I don’t know.” Whitmore’s voice was barely a whisper. “He came to me a month before his death. He told me he had found something. That he was going to make things right. He asked me to protect his papers until he returned. Then he went to the Bodleian, and—” He stopped. “I never saw him again.”

Eliza’s mind was racing. Marcus had been researching the poison. Marcus had been the Librarian, keeper of secrets and poisons. Marcus had gone to the Bodleian and died. And now the Codex of Nero was sitting in a reading room two floors below them, its recipe intact, its margins marked with Marcus’s trembling hand.

“The codex,” she said. “Where did it come from?”

“It resurfaced at auction five years ago. Purchased anonymously. Donated to the Bodleian with the condition that it be made available for scholarly study.” Whitmore shook his head. “Marcus believed the donor was connected to the society. He suspected it was a warning.”

“A warning about what?”

“About the poison. About what it could do. About the fact that someone knew it existed and wanted to ensure it was never used again.” Whitmore’s eyes were dark. “Or that they wanted to remind the Archai that the recipe survives. That they can still reach—anyone.”

Eliza’s father had been a warning. That was what Whitmore was implying. A demonstration of what the Archai, or someone within them, could do to an inconvenient question.

“Who killed my father?” she asked.

“I don’t know. I truly don’t.”

“But you have suspects.”

Whitmore’s silence was longer this time. When he spoke, his voice was rough. “After you leave this office, you will not return. You will not ask me again. I have told you more than I should—more than I ever intended. I owed Marcus a favor, yes. And now I have repaid it by telling you the truth. That is all I can give you.”

He stood and walked to the window. His reflection was pale in the glass.

“There is one more thing,” he said. “Marcus wasn’t the only one studying the Codex. Lord Wren requested the manuscript six months before Marcus’s death. The reading room records will show it. I know because I granted the request.”

Eliza stood. Her legs felt weak. “Wren?”

“Be careful, Eliza. Wren is not a man who issues warnings. He issues verdicts.” Whitmore turned to face her. “If I were you, I would find the codex’s original owner. The anonymous donor. That is the thread Marcus was pulling before he died. And it is the thread that will kill you if you pull it too hard.”

He crossed to the door and opened it. The gesture was unmistakable. Eliza walked past him, into the corridor, her mind churning. She had come seeking answers about her father. She had found a conspiracy. And now she knew one more thing, something she had not known when she walked in:

Marcus Whitmore was afraid. Not of her. Not of the council. Of a man who issued verdicts.

And Eliza was beginning to understand that she had been looking for the wrong kind of answer this entire time. She had been looking for a reason. What she needed was a weapon.

The Codex of Nero was made of paper, ink, and poison. But there were other poisons. And she intended to find them all.
