The Accused (1949)

Wilma Tuttle, psychology professor, lets aggressively brash student Bill Perry drive her home. Big mistake. After an attempted rape, Perry is dead; panicked, Wilma hides her traces and flees. As time passes, she watches the investigations of Homicide Lt. Dorgan with painfully concealed apprehension. Complicating matters: her budding romance with Warren Ford, Perry's guardian. How long can she stand the strain?
