Maj Berg (Ulla Jacobsson), who’s in charge of a fashion firm, realizes that she’s being stalked by a man who’s recently strangled a woman. At the time of the premiere, this thriller earned comparisons with international films, the most obvious example being Gaslight (1944). Poorly paced, too repetitive and Arne Mattsson fails to make the most out of his strangler, a character that becomes too bland. It’s a pity, because the cast is pretty solid and the best ingredient is Georg Riedel’s creepy music, set to a few effective scenes in a darkly autumnal Stockholm.
