Firewall, Paperback

Stopping to use a cash machine one evening, a man falls to the ground: dead. A taxi driver is brutally murdered by two teenage girls who demonstrate a complete lack of remorse. One girl escapes police custody and disappears without trace. Soon afterwards, a blackout covers half the country. When an engineer arrives at the malfunctioning power station, he makes a grisly discovery... Inspector Kurt Wallander is sure that these events must be linked - somehow. Hampered by the discovery of betrayals in his own team, lonely and frustrated, Wallander begins to lose conviction in his role as a detective. And somehow these criminals seem always to know the police's next move.
