A vile criminal who eluded police for 17 years

Martin Clunes again takes on the low-key yet effective persona of DCI Colin

Sutton, having played him in the first series about the investigation to catch

Levi Bellfield, who murdered Milly

Dowler in 2002. This time the story is of a criminal who burgled homes and, shockingly, raped and sexually assaulted elderly people over 17 years before he was finally caught. In a terrific performance, Clunes seems to have grown even more into the part of the eagle-eyed policeman, who is drafted in to re-energise a directionless team, while the four-part series really highlights the painstaking and forensic nature of great detective work.
