Harry Slater is the late father of ex-police officer Roy Slater first mentioned in "May The Force Be With You" when his son arrested him for having a defective rear light on his bicycle. Harry would die a few years after Roy was arrested in "To Hull and Back", and Harry's widowed wife Ruby wrote a letter to the prison governor not to give her son compassionate parole.
