Violación fatal (1977)

In the psychological thriller Violación fatal (1977), a writer retreats to a remote hotel to work on his novel but discovers that he’s got his hands full with a psychopathic innkeeper. Ágata Lys plays Veronica, the mentally unhinged owner of a country inn. The writer (Prince Heinrich Starhemberg) is quick to recognize her quirks--she’s imagined a husband for herself and seems repulsed by all mention of sex. But when the inn’s guests begin getting knifed to death, the writer realizes that the woman’s fragile psyche is more dangerous than he realized. Lys is picture perfect in the role of the villainous femme fatale--even knowing her propensity for murder, it’s hard to resist her tantalizing curves. Isabel Pisano also appears as the writer’s wife, and her happy screwing only serves to incense the jealous Lys.
