His final screen appearance was in an episode of the romantic comedy series "William and Mary" (2004), directed by his son Matthew, which also co-starred Martin Clunes (who, coincidentally, is the nephew of Evans' colleague Jeremy Brett). Evans made few appearances in films. His most prominent parts were as a murderous teacher in "Walk a Crooked Path" (1969), and as a detective in the thriller "10 Rillington Place" (1971), the film about the infamous British serial killer John Christie starring Richard Attenborough.

Serial killer Serial killer A serial killer is typically a person who murders three or more people, usually in service of abnormal psychological gratification, with the murders taking place over more than a month and including a significant period of time between them. Different authorities apply different criteria when designating serial killers. While most set a threshold of three murders, others extend it to four or lessen it to two. The Federal Bureau of Investigation (FBI), for example, defines serial killing as "a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone".
