In the final days of summer in 2013, a young woman is shot dead in her apartment. Three floors above, the blue lights of the police cars awaken Leo Junker, a long-time police officer. Leo works in the internal affairs division as the lowliest form of officer a spy. Leo is even lower, however, having been suspended after committing a terrible mistake.
He can't stay away for long. A series of frightening connections emerge, linking this new murder to Junker's own troubled youth and forcing him to confront a long-ago incident that changed his life forever. Now, in backstreets, shadowed alleyways, and decaying suburbs ruled by Stockholm's criminal underground, the search for the young woman's killer and the truth about Junker's past begins.
