The striking seventh novel in the Martin Beck mystery series by Maj Sjöwall and Per Wahlöö, finds Beck facing one of the greatest challenges in his professional career.

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 strong-arm police work and shear 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 Beck, his investigation unearths evidence of police corruption. That’s when an even stronger sense of responsibility and something like shame urge him into taking a series of drastic steps, which lead to a shocking disaster.
