Mai Cheval and Per Vale are Swedish journalists, authors of the famous series of novels about Commissioner Martin Beck, which received prestigious literary awards both in Europe and America. In the latest novels in the series, the immersion in the social context becomes even deeper than in the first books. A 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 the contradictions in it, and senior police officials who believe that such scrupulousness is unnecessary and even harmful. They prefer the figures of the new formation, like Sten Ohlsson with the characteristic nickname Bulldozer, who go ahead and know how to “pull by the ears” the necessary versions. What will such haste lead to? This book includes the last three novels of the decalogy: “The Locked Room” (1972), “Cop Killer” (1974) and “The Terrorists” (1975).
