My Novel 'The Versailles Formula' Is on Sale

The day has arrived!

The Versailles Formula, my eighth historical novel, is available in paperback and ebook format in North America, the United Kingdom, and Australia. I've created a suspenseful story rich with atmospheric detail that I hope will plunge you deep into mid-18th-century England and France.

Here's the story:

May 1766: Genevieve Sturbridge lives a quiet life in the countryside with her husband and son. But an invitation to dine at Sir Horace Walpole's eerie Gothic estate pulls her back into a deadly world of espionage. Genevieve uncovers a shocking secret - a rare pigment of pure blue is being produced again. Coveted by royalty, chemists, and spies, the formula is priceless . . . and lethal. Only Genevieve can recognise the formula and discover the truth before time runs out, because this time the price of failure will cost more than just her own life.

What Other Authors Say About 'The Versailles Formula'


With one day left before the official publication of The Versailles Formula, I would love to share the early reviews and endorsements from other novelists. Some are historical novelists, some are thriller writers, and some are historical mystery scribes. I deeply appreciate the time they took to read it and wanted to share the response to the book from my peers.






"Nancy Bilyeau's Versailles Formula is the continuing compelling adventure of whip-smart and determined heroine Genevieve Planché. It’s replete with spies, political intrigue, gorgeous gothic manor houses, romance, impeccably researched history—and the shocking history of the color blue."

--Susan Elia MacNeal, New York Times bestselling author of the Maggie Hope series



"A plucky heroine, intriguing mystery, and rich, well-researched historical background. Nancy Bilyeau has found the winning formula!"

--Eva Stachniak, author of The School of Mirrors



"Nancy Bilyeau has done it again. It is a masterful work which weaves great characters not to mention a plot that Poe himself would love. The story unfolds through the eyes of the protagonist and we see a treacherous world where nothing is as it seems. When we enter the Gothic world of Sir Horace Walpole then the reader treads a thrilling path which keeps you on the edge of your seat."

--Griff Hosker. author of An Officer and a Gentleman


"The excitement and action ramp up steadily, and Bilyeau's exquisite pacing will have you wanting to binge the novel in one sitting. Part espionage novel, part intriguing look at the historical importance of art and the porcelain industry to 18th-century diplomacy, The Versailles Formula is a riveting and deftly written tale that will keep you up much too late at night, for all the right reasons."

-- Paulette Kennedy, author of The Artist of Blackberry Grange



"Bilyeau gives the reader a fabulous tour of 18th-century Paris from its convents and opera houses to the louche masked balls of the aristocracy. Genevieve is a complicated, highly intelligent character who never falls into the dull predictability of the "spirited woman ahead of her time" tropes. The ending leaves the possibility open for another Genevieve Planche novel, and I very much look forward!"

-- Mariah Fredericks, author of The Wharton Plot


"In Genevieve Planché, Bilyeau has created a wonderfully wilful woman: as smart as she is sensitive, as brave as she is bold. Compelling to read . . . This is a series going from strength to strength."

--Kate Braithwaite, author of The Scandalous Life of Nancy Randolph



"An indomitable artist turned spy heroine on a near impossible mission. A color of blue so seductive that men will kill for it and countries will go to the brink of war. A star-crossed love, as delicious as it is forbidden. Thoroughly researched and exquisitely wrought, The Versailles Formula has all the ingredients of a rollicking, riveting historical mystery must-read!"

-- Hope C. Tarr, author of Irish Eyes and Stardust



"What impressed me the most is her gift for detailed description. When Genevieve lands in Paris to begin her dangerous mission, we can see the narrow streets with their buildings that 'sagged towards each other, nearly touching.' Inside the Comedie Française, we smell the 'thick, intoxicating swirl of perfume, a hothouse of human flowers blooming all at once.' And we can laugh at the absurdity of the nobility in their white silk socks, jeweled shoes, and heads covered in wigs that 'resemble sparkling beehives.' The Versailles Formula is a master class in the lost art of description, and I loved it for that."

--Jodi Daynard, author of A Transcontinental Affair


"With action-packed scenes to rival the classic The Scarlet Pimpernel, Nancy Bilyeau's excellent third book in the Genevieve Planché series, The Versailles Formula, solicits page-turning suspense until the very end. Reader, be ready for the world outside of reading this book to disappear."

-- Susan Wands, author of Magician and Fool


"Nancy Bilyeau's engaging protagonist, Genevieve Planché, returns in an undercover mission to 18th-century Paris, where she risks her life to unearth a secret that could reignite war between England and France. But Genevieve’s quest is as personal as it is political — Cracks have begun to form in her once-happy marriage, and she finds herself drawn to the man assigned to be her partner in France. With a cast of real and fictional figures, prose as smooth as French silk, and breathtaking twists, The Versailles Formula is exactly the book any lover of historical fiction would want to have in their hands right now."

-- Mally Becker, author of The Paris Mistress


"Thanks to the depth of Bilyeau’s craft, readers will share Genevieve’s tension and fear as she races through settings from rough, working-class Southwark to glittering Versailles. As Genevieve’s heart races, so will yours. If you like your mystery with twisty, dark history, The Versailles Formula is for you."

-- Sophie Perinot, author of Medicis Daughter



"Sumptuous and deeply engaging, Nancy Bilyeau's Versailles Formula is a gorgeously written adventure . . . brimming with mystery, beauty, romance, and history's most fascinating luminaries."

--Emilya Naymark, author of Behind the Lie



"The action takes place in England and France, castles and cemeteries and chateaux, grand ballrooms, sinister prisons, and cloistered convents. Historical figures flit through, from Horace Walpole, the father of the Gothic novel, to the Marquis de Sade, who lived one. The Versailles Formula is Bilyeau at her best, a classic tale of mystery and intrigue that only lacks a cameo from a dueling D'Artagnan to make my life complete. If you've read the first two books in the series, this is one you've been eagerly awaiting. If you haven't, this is a hellacious introduction."

--Timothy Miller, author of The Strange Case of the Pharaoh's Heart.



"The Versailles Formula takes readers on a fascinating journey to eighteenth-century England and France, where vicious aristocrats play a deadly game of forgery and espionage . . . Nancy Bilyeau treats us to another tale full of intrigue and delightful historical details."

-- Mark Alpert, bestselling author of The Doomsday Show

A New Design for My Genevieve Planché Series

After I turned in my final edits on The Versailles Formula, I felt a tug of excitement over seeing what cover design my publisher's designer had created for the novel. Both The Blue and The Fugitive Colours displayed lovely covers, and I was curious to see the plan for the third in the series.

To my surprise, my editor emailed me that the team at Joffe Books had come up with a bold new idea: to redesign the covers of the first two novels along with the cover of the third. The series would take a fresh approach, emphasizing that these were suspenseful historical novels with a woman protagonist at the center who was facing obstacles and searching for answers. (Once I think about it, the covers of the first two, while striking, did not convey that.)

They fiddled and fussed over the details for a while—I have to say the suspense was building in my house! But when my editor emailed me the covers, I was enthralled. They have a rich atmosphere, a touch of eeriness, and a mood that I think conveys the spirit of Genevieve Planché.

Here they are:






I hope you like the new look of the series!


To kick off the series and find new readers, The Blue's ebook is discounted at 99 cents (or pence)

Cover Reveal of 'The Versailles Formula'

 I am so excited to share the cover of my third novel in the 18th-century Genevieve Planche series: 'The Versailles Formula.'


Genevieve Sturbridge has left the dangers of London for a quiet life in the countryside with her husband and young son. But when she is invited to a dinner party at Sir Horace Walpole’s magnificent Gothic estate, she is drawn into a terrifying web of deception, espionage and murder.

At the mysterious dinner party Genevieve makes a shocking discovery — a secret pigment of the deepest, purest blue is being produced once more. The formula is so rare, it’s the obsession of chemists, royalty, and spies.

Some will kill to possess it. Others will kill to keep it buried.

Only Genevieve can recognise the formula and stop it falling into the wrong hands. But when a ghost from her past resurfaces, Genevieve must determine who she can trust. Years ago, this secret nearly cost her and her husband their lives. Now, someone is willing to kill for it once more.

Genevieve must discover the truth before time runs out, because this time the price of failure will cost more than just her own life.
