It's been a while since a giallo title has cropped up for Title Card Tuesday, so here's a firm favourite, the super sleazy whodunit caper starring Farley Granger and Sylva Koscina. Also known under the provocative title, The Slasher is the Sex Maniac, as Penetration (a cut that features hardcore inserts with Harry Reems & Kim Pope), and by the lengthy original Italian title, Rivelazioni di un maniaco sessuale al capo della squadra mobile.
