She married for love. Now she must spy on her guests.
Elizabeth Darcy has mastered the art of being Mistress of Pemberley—until the Home Office asks her husband to host a group of American diplomats suspected of conspiring with Bonapartist agents. Suddenly, her drawing room becomes a battlefield, and every dinner party is a test of loyalty.
But when she discovers the brilliant American cryptographer Silas Vance is using her beloved library for a dead-drop system, Elizabeth can’t resist cracking the code. The messages reveal a plot to liberate Napoleon from St. Helena—and a web of secrets that threaten to entangle everyone at Pemberley.

Darcy’s duty. Elizabeth’s curiosity. And a dangerous American who makes her question everything.
As intellectual sparring turns into something more complicated, Elizabeth must navigate a world where a misplaced word isn’t just a social faux pas—it’s treason. Because in 1815, the line between enemy and ally is written in invisible ink.
Pride and Prejudice meets John le Carré in this Regency spy thriller where wit is the deadliest weapon and love is the ultimate risk.

In a house full of spies, who can be trusted?
As Darcy navigates the icy waters of international diplomacy, Elizabeth must use her keen wit to outmaneuver a master codebreaker. From the silent galleries of Pemberley to the rain-swept docks of Liverpool, the Darcys must work as a team to prevent a global catastrophe.

In this high-stakes JAFF variation, a misplaced word isn’t just a social faux pas—it’s treason.

📝 AUTHOR'S NOTE
Dear Reader,

I wroteThe Federalist at Pemberley because I wanted to answer a question that haunted me after every re-read of Pride & Prejudice:
What if Elizabeth Bennet's intelligence wasn't just social—but operational?
Jane Austen's heroines are brilliant observers of human nature. They decode social hierarchies, detect hypocrisy, and navigate power structures with surgical precision. In the Regency era, a woman's survival often depended on her ability to "read the room" and anticipate threats.

So I asked: What if the room Elizabeth was reading was a nest of traitors?
This book is my love letter to two genres I adore:
Austen's Regency World – where wit is a weapon, marriage is a legal contract, and social intelligence determines your fate
Le Carré's Espionage Craft – where loyalty is currency, information is power, and everyone plays a double game

What you'll find here:
Elizabeth's sharp tongue deployed against bureaucrats and spymasters
Darcy's "pride" reframed as operational security (never reveal your assets)
A Regency England where the real war isn't on the battlefield

If you've ever wanted to see Elizabeth Bennet outwit a spymaster, dismantle a conspiracy, and marry Darcy —
This book was written for you.

With gratitude and a loaded flintlock,
Iviana Hedera
