to win her back in the eleventh series. Criminals and their families Ricky Hanson Ricky Hanson (David Troughton) (2006–2009): Ricky Hanson is a career criminal whom Jack and Sandra were investigating for at least three murders in Jack's last case before he retired. This was no coincidence, as an investigation by UCOS several years later revealed that Hanson had run over Jack's wife, Mary. Jack retired to care for Mary, although she did not live very long after the incident, which was thought to be a simple hit-and-run. When Jack confronts Hanson, he cruelly confesses the crime in detail, prompting Jack to attempt revenge by running the criminal down, but Jack is prevented from doing so. Hanson later attempts to murder Jack in the hospital by smothering him with a pillow but is stopped by Brian. When Hanson attempts to strangle Brian, Jack strikes him with an oxygen cylinder. Hanson is subsequently found not guilty on the charge of attempted murder. However, in an apparent continuity error, no reference is made to a ward nurse being attacked by him during the incident. Later, in the sixth series, Hanson is linked to the disappearance of two Anti-Fascist activists. UCOS discover from Frank Patterson that Hanson's son, Luke, was in the car that ran down Mary. Luke admits this when it is revealed that Ricky has had an incestuous relationship with his secret daughter. Luke also had a relationship with the girl, although neither knew they were half-siblings at the time. Ricky is arrested for running down Mary, as well as the murder of the activists, and is sent to prison. Luke Hanson Luke Hanson (Joe Absolom) (2006–2009) Luke is the son of Ricky Hanson and gets his father arrested for the murder of Jack's wife Mary after he admits he was in the car with his father.
