A widow must complete an undercover mission-and deal with feelings for an alluring man with a secret identity of his own-in this sensual, witty historical romance perfect for fans of Evie Dunmore and Netflix's Bridgerton!

Mrs. Euphemia Blount has spent a lifetime hiding her true feelings and conforming to others' expectations. So when the Wimpole Street Widows Society save her from certain death, it's natural for her to join them, and even more natural to do what she does best: disguise herself to help those who need it most. But when a mission has her going undercover as a lady's maid at an exclusive house party, the one thing she doesn't expect is to start falling for a valet.

Mr. Lucas Ducret spent a decade chasing the French spy La Vipere during the war, desperate to bring her to justice for the betrayal and execution of his father. After an accident that left her dead and him wounded, he has lived a ghost of an existence. Now, he has received word that La Vipere escaped and is, in fact, alive. He disguises himself as a valet at a country house-only to meet a lady's maid who touches his heart in ways it hasn't been before.

But with a French spy hiding somewhere in the house, danger lurks around every corner. And when true identities are discovered, betrayal threatens to destroy whatever tentative hope has managed to bloom between them. As Euphemia and Lucas realize that their disguises may have given them the freedom to finally be themselves, they must ask themselves which is the more dangerous mission-facing a murderous spy, or being true to their hearts?
