Young Scout Edvin is dropped on a deserted island and ordered to gather mushrooms and berries for the communal pot. But he’s in for a different kind of discovery—a shot-through human skull. The inquisitive teenager realizes he must show it immediately to the police commissioner and his older friend at home, Everth Bexström. The official investigation begins with genetic testing, which identifies the victim. The result shocks: this woman died twice! An opening like that would throw off a less experienced investigator, but not Bexström—because he’s made his name as the best specialist in murder investigations.
