This is Pippa Scott's final appearance playing Molly Wood. Subsequently, Molly Wood is not seen after Season One but is sometimes mentioned until finally 'killed' in Season Two Ep11. This contrasts the book, where Molly Wood remains a major character throughout.
Tom Tyron and Carol Lynley, who are teamed romantically in this episode, appeared as brother and sister the next year in "The Cardinal" (1963).
