Piet Hoffmann burned inside Aspsås prison
Piet Hoffmann, a former convict working undercover for Swedish police inside a Polish mafia front, is sent into Aspsås prison to take over its drug trade, with senior police and government officials approving the plan in secret. When detective Ewert Grens's inquiry into a killing at a Stockholm flat, where Hoffmann was present, begins pointing at the operation, those officials leak that Hoffmann is an informer, which makes his death inside the prison almost certain.
