Arne Dahl - Valaki figyel

In Västeras, Sweden, a fifteen-year-old girl disappears without a trace, and a year later another similar case occurs. Inspector Sam Berger, who investigates the cases, finds only one tiny metal gear after the victims, but he is sure that they were left there by someone who knows that he will understand the mysterious clues.
Soon a third teenage girl goes missing, and Sam tries to convince his superiors that they are dealing with a serial killer. The police continue to search for victims, and Sam is forced to face his own long-buried demons once again. He has no other choice if he wants to decipher the message of the killer, who seems to kill only for his "sake"...
