This episode opens with a young drug dealer having run-ins with various characters; the next day his body is discovered, he had been stabbed to death. Beck's team are on the case and quickly link the victim to a small shop; here they make an arrest of a man who tried to flee and is carrying a pistol and drugs. Once he is in the car he demands to be released... he is an undercover policeman, named Josef Eriksson.
I thought this was a decent enough episode; even though Beck's role in the series that bears his name seems to be diminishing. The central mystery had a good number of twists with suspicions about Eriksson remaining for much of the episode. Some humour is provided when colleagues encourage Steinar to sign up to dating app Tinder. The cast does a solid job throughout. This might not be the best episode but I thought it got the latest season off to a solid start.
