Annie looks after a ghost mother's ghost baby for a day, making George broody and keen to move in with Sam and her brattish daughter Molly. Chief Constable Wilson fetches Mitchell to kill a paedophile but Mitchell refuses, recalling an incident from forty years earlier with Herrick when he first learnt to experience compassion (and where Herrick got the idea of being a policeman). He warns the offender to give himself up instead and later kills Wilson. Covered in the policeman's blood he arrives for a dinner date at Lucy's flat. She knows he is a vampire and has a stake, given her by Kemp, with which to kill him.
