Sandra Dee stars as Millicent, a young woman whose twin sister Marion, a tap dancer, has committed suicide while alone one night. Then Millicent comes to believe she's being haunted by the sibling, as she is always hearing piano music in the house and hearing the sound of tap-shoes. All of this while she is being pressured by a developer (Dane Clark) who wants to purchase her property.
This whole tale has too much familiarity for it to be completely effective (all the way to the reveal & resolution), but at least director Jeannot Szwarc builds up a respectable atmosphere and mood. It also helps that Dee is so affecting in the main role, and she does make Millicent a sympathetic character. She receives able support from an under-playing Clark, a likeable Christopher Connelly as her well-meaning friend, and a solid Russell Thorson as a very straightforward and forthcoming doctor. The house itself has an ominous presence, and Eddie Sauters' music is good.
This one has good intentions, but isn't one of the more inspired 'Night Gallery' episodes.
Written by Gene R. Kearney, based on a story by series producer Jack Laird.
