 The drugs-related death of young man who lapsed into a coma at a rave club attracts the interest of Dalziel ( Warren Clarke  (qv)) and Pascoe ( Colin Buchanan  (qv)). As the detectives investigate deeper into the rave club they discover that the club is owned by Nicholas ( Andrew Lee-Potts  (qv)) and Sophie ( Sarah Jane Potts  (qv)), intense, inseparable twins and financed by their seemingly benign Uncle Henry ( Bernard Cribbins  (qv)), a maker of perfume. This bizarre trio cause problems enough for Dalziel but he comes under more pressure when, during a drugs raid, he arrests the son of his ex-wife, Mary Waddell ( Harriet Walter  (qv)). After another strange murder at the club, Dalziel and Pascoe are forced to dig even deeper into the private lives and motivations of the diverse group of suspects surrounding these murders with some startling results.
