Rhoda Gemignani, George Pan Andreas. Establishes a sympathetic character as prime suspect from the get-go and spends the hour teasing us as to their guilt or innocence. As the time passes we get more and more invested in their story, their love life and in the person that cares about them, hoping that when the end comes they are not revealed as the killer. Superb episode that achieves exactly what it sets out to do. 10/10
