This Danish crime thriller is so dark and stormy it will leave you dazed as the credits roll. ‘The Absent One’ is the second instalment of the bestselling Department Q series of novels by Jussi Adler-Olsen and follows a boozy, brooding cold-case cop and his rational-thinking partner as they investigate a spate of twisted crimes that took place at a posh boarding school in the ’90s. In some ways the film is quite formulaic: you can guess who the bad guys are from the word go. Still, it’s a pleasure to watch. Suspense is built with gory flashbacks and a willingness to show cruel violence without cutting away. Expect to feel tense right up to the end.
