The brick house with imitation Greek pillars around the front door, used as Rose Mellors' house, was also used as Johnny and Sheila Lyon's house in Queen's Pawn (1975).
Rose Mellors' white Mercedes 450SL bears the registration EUU 47V. This registration also appeared on a yellow Rover 2000 driven by Trenchard in Trenchard's Last Case (1989). According to DLVC records, the registration has never been used and is therefore fictitious.
Rose Mellors, played by Ann Lynn and Jack, played by Tony Selby previously appeared in Bury My Half at Waltham Green (1979)
