After her twin sister Marian hangs herself, Millicent (Sandra Dee) returns home, only to hear Marian – a dancer – tapping across the floor upstairs, footsteps rapping in the room where she left this world.

“Specter In Tap Shoes” was directed by Jeannot Szwarc and written by Gene R. Kearney from a story by Jack Laird. After the death of her twin, Millicent is sure that Marian is still here, as she doesn’t just hear her; she smells the smoke from her cigarettes.

Maybe she should just leave. That’s what William Jason (Dane Clark), a property developer who is a mutual friend of Millicent’s pal Sam (Christopher Connelly, soon to depart for Italy), thinks would be best. She’d get closure and away from all the memories.

Millicent keeps hearing her sister’s voice, urging her to hang herself as well. She stops at the last minute and finds William in her sister’s studio. He demands letters that Marion wrote to him, letters that she somehow can discover immediately. She also finds a revolver that she uses to shoot him.

The logical explanation is that the entire house was wired so William could gaslight Millicent just like he did Marion. But then, how did she know where the letters were?

This is a decent enough episode, but as always, Serling writes the better Night Gallery stories. Szwarc does a good job of making the story mean more than it does.
