Sweden, winter, 1991. Inspector Kurt Wallander and his team receive an anonymous tip-off. A few days later a life raft is washed up on a beach. In it are two men, dressed in expensive suits, shot dead.<br> <br> The dead men were criminals, victims of what seems to have been a gangland hit. But what appears to be an open-and-shut case soon takes on a far more sinister aspect. Wallander travels across the Baltic Sea, to Riga in Latvia, where he is plunged into a frozen, alien world of police surveillance, scarcely veiled threats, and lies.<br> <br> Doomed always to be one step behind the shadowy figures he pursues, only Wallander's obstinate desire to see that justice is done brings the truth to light.
