Cold Light 
(Resnick 6)

»Forty-eight hours, that»s what they reckon, isn»t it? Forty-eight hours. If you don»t find them in that, likely they»re sodding dead…»
A cabbie»s just been beaten up, there»s a drunk and disorderly in the interview room and a possible child abuser on the way in. Nothing unusual there, then, just a pretty normal Christmas holiday for DI Resnick and his team.
Normal, that is, until Dana Matthieson calls to report her flatmate, Nancy, missing.
Dana»s had a pretty grim Christmas herself: she»s been sexually harassed by her boss, and may even have lost her job as well as her friend. Pretty soon the police have proof that Nancy was kidnapped, and then – as the New Year celebrations wind down – the first tape arrives, and Resnick knows they»re dealing with a dangerous psychopath.
