Den första kvinnan

A few days before Christmas Eve 2023, a 17-year-old boy is shot to death at a tram stop in central Norrköping. At first, the police have no leads on the perpetrator, but the case soon escalates when it turns out that there are connections between the murder and a previous attempted murder where the same weapon was used. It soon turns out that it may be a contract killing and there are also many indications that the murderer may be a woman.
