Don't listen to the Hype. It's awful

What a freaking movie. So many twists and turns. Absolutely intense from start to finish.

By the time the dramatic fireworks start popping off, each one feels earned.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

A train journey represents a tension-building arena. Specially if you intend to have a large number of participants killed. This is a Sjöwall/Wahlöö script. Trying to argue that the murderer is among us. Could be your or me. An odd and intriguing ensemble of men and women. Hyperactive acting and editing. Not a quiet moment. And a strange mix of comedy and thriller. Some forced nudity. Kinky at times. With prejudice, the film describes deviant sexual behavior A couple of train passengers are also reported to have been treated at a mental hospital. Allan Edwall, Heinz Hopf, and Erik Hell stands out. Unusually many good female roles. A typical Swedish film from the mid-sixties. "Mördaren is a consistently dispassionate and highly gross film". - Stig Björkman Chaplin.
