From the recent reading piles I've been catching up with - strong first book in what's intended as an ongoing series.

From the Blurb:

London, 1863: Women in Waterloo are turning up dead, their sexual organs mutilated and removed. When another girl goes missing, fears grow that the killer may have claimed their latest victim.

The police are at a loss and so it falls to courtesan and professional detective, Heloise Chancey, to investigate.
