Poseídas del demonio (el perfume de la señora de negro)

Like Barbara Bach, Mimsy Farmer went to Italy and fell in love. She did, however, have a long career in the US, starting with Gidget Goes Hawaiian to a few biker movies. She remained in Italy making films until her divorce, and then moved to France where she continued acting.

This is more a psychological horror film that a true giallo. It was a tale of a woman going mad over unresolved traumas from her childhood. Or, maybe it was a tale of a woman being driven mad for nefarious purposes. It was not totally clear, but there were little clues throughout.

Whatever the case, the ending was a total surprise and nothing led you to expect it.
