Your Vice Is a Locked Room and Only I Have the Key
An Italian twist on Poe’s “The Black Cat.” All the standard giallo elements are here in this better-than-average entry into that genre.
UPDATE: It’s summer 2020, and I have re-watched this along with Sergio Martino’s other Giallos from the same period. This is the weakest of the lot and I found the depictions of domestic abuse to be just too much to believe. Although, Edwidge has never looked better than she does with her short hair style here.
