Creep

If he can''t have her...
Psychology professor Dr Sheila Tao is an expert on human behaviour, so when she begins an affair with charming graduate student Ethan Wolfe, she''s well aware she''s playing with fire. Consumed by lust and riddled with guilt, Sheila ends their three month fling when she becomes engaged to a kind and loving man who adores her. But Ethan has different plans...
NO ONE CAN.
When a star student is stabbed to death, it''s clear someone is raising the stakes of violence, sex and blackmail on campus. Before long, Sheila is caught in a terrifying cat-and-mouse game with Ethan: the lover she couldn''t resist is now the monster who will never let her go.
