Historical Fiction Book Launch: The Versailles Formula (The Genevieve Planche Mysteries Book 3) by Nancy Bilyeau

Available from Amazon UK and Amazon US 

Genevieve Sturbridge thought she’d left danger behind in London. Now she 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 deception, espionage and murder.

A missing formula. A deadly secret. A race against time that could alter the fate of nations. In the simmering unrest of 18th-century Europe, Genevieve Sturbridge is thrust into a perilous mission—one she never imagined but cannot refuse. 

A formula for a dazzling shade of blue has resurfaced, one tied to alchemy, espionage and a power that could tip the balance between France and England. Some will kill to possess it. Others will kill to keep it buried.

As revolution stirs and shadows lengthen in the ornate drawing rooms of Paris and the back alleys of London, Genevieve must navigate treacherous alliances and a past that refuses to stay hidden. The formula’s secrets could bring untold wealth—or unimaginable destruction.

 

With time running out, Genevieve must unravel the mystery before the Versailles Formula falls into the wrong hands — because this time, the price of failure is more than just her own life.
