London, 1839. With the cemeteries full and money to be made in death, tricksters Crawford and Bonnie survive on wicked schemes and ill-gotten coin. But one blistering evening, their fortunes flip. A man lies in a pool of blood at Bonnie’s feet and now she needs to disappear.

Crawford secures her a position as lady’s maid in a grand house on the Thames. As Bonnie comes to understand the family – the eccentric Mr Moncrieff, obsessively drawing mausoleums for his dead wife, and their peculiar daughter Cissie, scribbling imaginary love letters to herself – she begins to question what secrets are lying behind the house’s paper-thin walls and whether her own presence here was planned from the beginning.

Because Crawford is watching, and perhaps he is plotting his greatest trick yet . . .
