"Il tuo vizio è una stanza chiusa e solo io ne ho la chiave", a.k.a. "Your Vice Is a Locked Room and Only I Have the Key" is a giallo with despicable characters and a good story based on Edgar Allan Poe's "The Black Cat". The plot has racism, lesbianism, orgy, betrayal, drugs, alcohol, abuse, prostitution, and in the present days when the "politically correct" rules, Sergio Martino could have problem with this film. But fortunately it was made in the 70's. My vote is seven.
Title (Brazil): "No Quarto Escuro de Satã" ("In Satan's Dark Room")
Note: On 14 June 2020 I saw this film again.
