Your Vice Is A Locked Room And Only I Have the Key - 1972 - 6/10
AKA - Il Tuo Vizio è Una Stanza Chiusa e Solo io ne ho la Chiave

Kinky, sleazy, degenerate, incestuous, oft times confusing, but what the hey?
An entertaining Giallo with plenty of twists and slashings to please cult fans.
Washed up, philandering alcoholic writer holes up in his inherited manor house.
He entertains homeless hippies, humiliates his downbeat wife, and chases tail when not suffering whisky dick.
When some of his paramours are split open with a hook knife, locale polizia zero in on him.
Out of the blue, his niece (the succulent Edwige Fenech) arrives and shares the velvet spasm with eager comers.
There are like five plots going on, but you will be transfixed by the nudity, rompings, gore, dirt bike races, and a contrary black cat named Satan who knows more than his human counterparts.
