Daughters of Night by Laura Shepherd-Robinson

From the author of Blood & Sugar, Daughters of Night is a chilling, evocative murder mystery set in the glimmering town houses and dark alleyways of Georgian London. 

From the brothels and gin-shops of Covent Garden to the elegant townhouses of Mayfair, Laura Shepherd-Robinson's Daughters of Night follows Caroline Corsham, as she seeks justice for a murdered woman whom London society would rather forget ...

Lucia's fingers found her own. She gazed at Caro as if from a distance. Her lips parted, her words a whisper: 'He knows.'

London, 1782. Desperate for her politician husband to return home from France, Caroline 'Caro' Corsham is already in a state of anxiety when she finds a well-dressed woman mortally wounded in the bowers of the Vauxhall Pleasure Gardens. The Bow Street constables are swift to act, until they discover that the deceased woman was a highly-paid prostitute, at which point they cease to care entirely. But Caro has motives of her own for wanting to see justice done, and so sets out to solve the crime herself. Enlisting the help of thieftaker, Peregrine Child, their inquiry delves into the hidden corners of Georgian society, a world of artifice, deception and secret lives.

But 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
