Paris, 1810.

Haunted by the French Revolution, Marie Tussaud has locked herself away in her shop with the death masks she was forced to make to avoid the guillotine. Philidor, a famous magician, offers her the chance to accompany him to London to assist in creating a wax automaton that will bring them both money and success.

Following a disastrous performance on their opening night in which the wax on their prized spectacle melts, the eccentric Duke, William Cavendish, invites them to his rambling estate, Welbeck, where he suggests they take up residence, use his underground ballroom for a new show and in return create a private commission for him: a wax automaton in the likeness of Elanor, a beautiful girl who mysteriously disappeared from the estate when he was a child.

In this delicious novel of twists and turns, Welbeck, with its locked doors and rooms, is full of secrets and no-one is who they seem. There is the seductive aura of Shelley, Dickens and Du Maurier in Tussaud. Marie must fight for survival in a world dominated by male advantage and power in a mesmerising story filled with wisdom about human behaviour and motivations.
