Likeable giallo with a bit of a gothic or even krimi feel.
Subs do exist for the old Italian vhs release.
However there seems to be missing info on the sides of the picture and also some footage seems to be misplaced.
I think this is a good description:
"Similar to 1967's Assassino Senza Volto in its melding of classical Gothic trappings with the giallo thriller elements just coming into renewed vogue, this castle-set horror mystery from Italian filmmaker Ferruccio Casapinta benefits from a slicker look and a better sense of humor. Casapinta lays on the atmosphere thick and heavy, with thunderstorms, howling wolves, and a Hammer Films-inspired score by Franco Potenza to heighten the mood. It all seems a bit overwrought, but fans of Italian horror don't come to it for subtlety. Indeed, the nearly operatic histrionics on display are immensely enjoyable..."

I do wonder how they forgot to mention Erna Schurer's (looking gorgeous here) nude scenes?
Trying to keep it civil...
