Ladies' Night — Elisabeth Bowers

Meg Lacey is hired to find two missing young women, 15-year-old Lillian Kubicek and 19-year-old Alison Chase. Lillian is found dead of a heroin overdose, and Meg believes she can tie the death to Alison's fiance Danny Haswell who owns a nightclub that Meg suspects is a cover for child-pornography and drug rings. What starts as mere guesswork is substantiated when Meg and her friend Johanna, a prostitute, visit the club on "ladies' night" and witness debauchery that unnerves even hardened Johanna. Eventually Meg finds someone within Haswell's organization who will supply the necessary details to launch a full-scale police raid, provided that her identity is not revealed. But it all turns sour when the raid results in murder and Meg holds the key to the killer's identity.
