Cilla Troughton is a character appearing in the episode Last Man Out of the ITV crime drama Midsomer Murders. She is the daughter of James and Germaine Troughton and the mother of Leo Henderson's son, whom she gave up for adoption. After 19 years, her son contacted his biological grandmother in order to find his mother, so he can reunite with her.
20 years prior to the events of the episode, Cilla was left sobbing at the foot of the big oak tree by Serena Luthando and Melody Henderson. They bullied her into running off into hiding after finding out that she had been having an affair with Melody's husband Leo, unaware she became pregnant after the fact. She kept in contact with St John Beachwood who acted as a father to her, since her father died when she was young.
