Daughters of Night (Broché)

London, 1782. Caroline "Caro" Corsham disco a well-dressed woman in the bowers of the Vauxhall Pleasure Gardens - mortally wounded and alone. When the Bow Street constables unearth the identity of the dead woman, they cease to care entirely. However, Caro has motives of her own for wanting justice done, so sets out to solve the crime herself, enlisting the help of thief-taker Peregrine Child. Their inquiries will throw them headlong into the deepest hidden corners of Georgian society, a world of artifice, deception and secret lives.
And with many gentlemen refusing to speak about their dealings with the dead woman, and Caro's own reputation under threat, finding the killer will be harder and more treacherous than she can know...
