Murder on the dance floor

The first death at the Kismet Klub in Newbury is put down to an Ecstasy mishap, and even when a second drug-related death is connected to the club, it doesn't occur to Superintendent Gregory Summers that there could be a serial killer. He does discover that the deaths are not due to Ecstasy, but to a new, lethal drug - Entium Trilenium. When DC Nicolaides's fiancee holds her hen party in the Kismet Klub, on the same night as an undercover police enquiry, the killer strikes again - terrifyingly close to home.
