Mai Cheval, Per Wahlöö. Locked Room. Police Killer. Terrorists

Maj Sjöwall and Per Wahlöö are Swedish journalists and authors of the famous series of novels about Commissar Martin Beck, which have won prestigious literary awards both in Europe and America.
In the final novels of the series, the immersion in social context becomes even more profound than in the earlier books. The conflict within the police itself comes to the fore: between old-school investigators like Martin Beck, who delve into the smallest details of a case to resolve all its contradictions, and senior police officials who believe such meticulousness is unnecessary and even harmful. They favor the new breed of investigators, like Sten Olsson, aptly nicknamed "Bulldozer," who take a head-on approach and are adept at pushing the right leads. What will this hasty approach lead to?
