"When his old friend and former colleague is shot dead at his home, Detective Superintendent William Lorimer is devastated. And his problems are only just beginning. It's not long before two further deaths are reported: both victims ex-policemen. This is a targeted campaign against their own, and with no other leads to the killer, Lorimer's team are panicking. Who will be next? Lorimer knows he must keep his cool if he is to solve the case. But with time running out before the next attack, he's struggling to ignore one horrifying question: Will he get to the killer before the killer gets to him?"--Page 4 of cover.
