This is one of two episodes which feature Susan Hampshire as guest star, the other episode being You're Not In Any Trouble, Are You? The episodes are not connected, however they do share similarities, including both characters Ms. Hampshire portrays have golliwog dolls, and the tune, Mio Amore Sta Lontano - an Italian haunting vocal version of The Zombie's hit, She's Not There, is used through each episode as a leit motif.
The doll is a Harlequin. Lesley has a line about him needing his Columbine.
