Maj Sjöval, Per Wahlö. Rosanna. The Swede Who Disappeared. The Man on the Balcony. Flight to the Scaffold.

Per Wahlöö and Maj Sjöwall 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.
The detective genre, under the pen of the couple Wahlöö and Sjöval, "ceases to be a figment of the imagination and a piece of entertaining fiction divorced from reality" (The Times). Certainly, each novel contains a challenging puzzle that the police officers led by Martin Beck must solve, but there is also a secondary context: Sweden of that time, with all its problems and contradictions. The reader follows the criminal through the real streets of Stockholm, becoming acquainted with both the best, most prestigious places of the Swedish capital and its lesser known corners.
This book includes the first four novels of the decalogy: Roseanne (1965), The Swede Who Disappeared (1966), The Man on the Balcony (1967), and Flight to the Scaffold (1968).
