Filmen heter Intruder (1999) med Charlotte Gainsbourg och Nastassja Kinski. Från en online-översyn :
Catherine [...] meets soundtrack composer Nick Girard (Charles Powell) at a gallery opening, and in no time they’re wed and she moves into his gorgeous loft-apartment. Nick doesn’t talk about [his previous wife] Stella, but Catherine learns she was found dead clutching a large pair of scissors amid signs of a fierce struggle. [...]
Despite its cutting-edge decor, the building is old, with a sinister handyman and electricity that often fails, requiring the use of candles and flashlights. Catherine starts noticing strange things around the house — a glass of wine with tell-tale lipstick, a brush with strands of someone else’s hair, a crooked painting, an unexplained reflection and, finally, a diary with the initials “SG.”
