The Son, Jo Nesbo

Sonny Loftus’ father was a dirty cop and Sonny is a killer doing prison time for two murders and now a possible third, but there is a conspiracy revolving around Sonny. For some reason it is important to keep him locked up and doped up on heroin. For if Sonny should somehow learn the truth he might be motivated to escape, clean himself up and go after his father’s killers.

And for some people that would be very bad news indeed.

N.B. This is not a Harry Hole novel.
