Cassie humors her fragile sister, Mia, who is recovering from a nervous breakdown, by purchasing two Harlequin dolls at a local antique store. The two dolls, one light-haired and the other dark, are a matching pair—like sisters!

Sibling rivalries from childhood begin to surface, as well as jealousy over Jason, who has married Mia, but was once Cassie's boyfriend. Cassie soon fears for her life when she receives a disturbing phone call in the eerie voice of Mrs. Jingles, her sister's doll. Is the toy bent on revenge for a sister scorned, or is Cassie about to encounter something even more sinister in the form of someone she's loved for years? A short story.
