She Slapped England’s Most Feared Duke… Then He Refused to Let Her Go

Chapter 3

“If you are correct,” he said, and his voice had dropped again, low and private, “then you have walked into this ballroom and accused the most powerful institution in England of forgery. If you are wrong —”

“Then you may ruin me,” she said, without hesitation. “Publicly. Thoroughly. I will deserve it, if I am wrong.”

A long silence followed. The Duke studied her as though solving a puzzle, as though she were a cypher and he had just found the key. His gaze moved over her face — the freckles she had never been able to hide, the stubborn set of her jaw, the widow’s peak of dark hair pulled into its neat governess knot. He looked at her the way men looked at maps of uncharted territory.

“Come to my library tomorrow night,” he said.

Isabelle froze.

A gasp rippled through the crowd — audible, unmistakable. A governess. At night. In a duke’s private library. Every whisper in every drawing room in London took root in that single instant.

“Your grace,” she said carefully, “I am a governess. Your sister’s servant. If I am seen entering your library at night—”

“You claim to understand patterns.” He stepped aside slightly, gesturing toward the back of the ballroom, where the great oak doors of Harrington House stood closed against the dark. “As it happens, the Crown has several messages that require deciphering. Messages that our own codebreakers have failed to solve.” His voice softened, and the change in it was almost intimate. “Prove your theory, Miss Fairmont. Solve them. And if you succeed —”

His eyes locked onto hers, and the next words fell into the silence of the room like lead.

“— I will personally reopen your father’s case.”

Isabelle’s heart slammed against her ribs. The ballroom felt suddenly too small, too warm, too bright. She could feel every eye in the room on her — the curiosity, the contempt, the envy, the greed. She could feel the scandal crystallizing around her like frost.

“Do we have an agreement, Miss Fairmont?”

She looked at him — the man she had just publicly humiliated. The man feared by half of England. The man whose family’s name had been burned into her memory five years ago, when the East India Company investigation had concluded that Thomas Fairmont, mathematician, had forged the records that ruined the Company — records his daughter had never once believed.

And yet, in his gaze, there was no anger.

There was curiosity.

Dangerous, burning curiosity — the same hunger that had lived in her father’s eyes when he leaned over a column of numbers and found the pattern hiding inside the chaos.

“Very well,” she said quietly.

The Duke’s mouth curved slightly — not a smile, precisely. The suggestion of one. A shadow of amusement, of anticipation.

“Excellent.”

He lifted his champagne glass again — the glass he had set down when she slapped him — and announced smoothly, to the ballroom:

“Let us continue dancing.”

The violins resumed. Conversations erupted. Scandal bloomed like wildfire in dry grass, and Isabelle Fairmont stood at the center of it, perfectly still, and realized something far more dangerous than humiliation had just begun.

She had challenged the most powerful Duke in England.

And somehow, instead of crushing her — instead of dismissing her, ruining her, discarding her as the world had taught her powerful men always did with inconvenient women — he had invited her into his secrets.
