Seventh novel in the Martin Beck mystery series. The gruesome murder of a police captain in his hospital room reveals the unsavory history of a man who spent forty years practicing a horrible blend of strongarm police work and sheer brutality. Martin Beck and his colleagues feverishly comb Stockholm for the murderer, a demented and deadly rifleman, who has plans for even more chaos. As the tension builds and a feeling of imminent danger grips Bec, his investigation unearths evidence of police corruption.
