This is American crime novelist Jim Thompson's turf, unquestionably. It's set in a small town where everyone knows everyone. Secrets are buried by the residents. The town has a bad person, and the local police force (just one man, in this case) get pulled in by the town's sinister past. A murder is covered up.

But then there's another, related, murder. Suspicion grows exponentially.

Terribly Happy begins with the punishment posting of a Copenhagen cop to a distant village because of something bad he has done (we learn the details later). This village is in the nastiest possible place, Jutland, a part of Denmark that looks like Kansas, but without the corn and loaded with swampy bogs. It's really depressing. The cop, Robert (Jakob Cedergren), tries his best to bring professional law enforcement to the town, but is almost immediately in trouble over his head.

This is a town that doesn't cotton to strangers. It doesn't help when the town nympho, an abused wife who is married to the town bully, starts coming on to him. This is the kind of town where if someone talks to someone in public, everyone knows immediately. These are not friendly people and they love to gossip.

Terribly Happy works as a primo noir because it is utterly plausible, right down to the bitterly ironic ending. This is an outstanding crime drama.
