The Duke and the Viper (Paperback) (ISBN-13: 9781068525230)

A haunted house. A ghostly child. A ruthless French spy.

When the Duke's sister invites Kate and Adam to her seaside home on the Lymington estuary, whispers of a child ghost are the least of their worries. Robbers and smugglers stalk the shoreline, and rumours spread of "The Viper," Napoleon's deadliest spy.

When the Duchess's young niece-secretly tied to the French monarchy-is targeted, the Duke and Duchess are drawn into a desperate race for survival. The Viper will stop at nothing to claim the girl and the royal secrets she carries.

From moonlit coves to shadowed forests, Kate and Adam must outwit smugglers, unmask a spy, and uncover the truth behind the ghost of the estuary. But as the chase closes in, one thing becomes clear: the Viper has already set his sights on them.

Thrilling, romantic, and laced with gothic suspense, The Duke and the Viper is the second dazzling instalment of The Halton Abbey Mysteries.
