From the Publisher:
The ritual murder of a prostitute named Ada McKinley in a bedroom on decrepit Pentecost Alley would ordinarily occasion no stir in Victoria's great metropolis. But, under the victim's body, the police find a Hellfire Club badge inscribed with the name Finlay Fitzjames - a name that instantly draws Superintendent Thomas Pitt into the case.
