A police officer is murdered with a bayonet while staying in hospital. The investigative team, lead by Martin Beck, soon discover that the man had frequently abused suspects as well as civilians but that any complaints had been ignored owing to the misguided loyalty of his colleagues. The volatile mind of the killer means that Beck has to resolve the case quickly before more people are hurt.
