The episode "The Grand Old Lady" was actually intended as an
"Ellery Queen" (1975) episode but was shelved after the series was cancelled. It was filmed as a
"Murder, She Wrote" (1984) episode using entirely new names for the characters, and Jessica was given the prologue and epilogue that originally belonged to the
Jim Hutton character Ellery Queen. The role of the radio reported was intended for the Simon Brimmer character, who was played by
John Hillerman. The role of the inspector, who's the "Ellery" character's father, was intended for
David Wayne.
