Twisted is a 1985 horror and psychological thriller directed by Adam Holender and starring Christian Slater, Lois Smith, and Tandy Cronyn.
One evening, the Collins, Phillip and Evelyn, a married couple with two children, discover their maid, Mrs. Murdock, dead at the end of their steps; her neck is broken.
She does not know Susan's teenage brother Mark (Christian Slater): technically skilled and good in school, but restive and cunning.
Helen simply turns down the offer and drives back home herself, with Phillip refusing to have her arrested immediately and suggesting they clean up the house.
Secretly, Susan dons her late brother's glasses and proceeds to listen to his Nazi music and the cycle begins anew.
