The Dark Mirror

Priscilla Maine, a wealthy young woman, is plagued by visions of menacing people and strange adventures, which she confides to Dr. Philip Fosdick, a young physician. Later, while reading a newspaper account of a crime, Philip recognizes the people from Priscilla's dreams and investigates. He discovers that Priscilla has a twin sister named Nora O'Moore, who has just escaped from the clutches of gang leader Red Carnahan. The criminal stalks Nora and takes revenge by drowning her in a lake. Priscilla has a vision that draws her to the lake, where she finds Carnahan. The gang leader, terrified by Priscilla's resemblance to his victim, is driven by fear to drown himself. Priscilla faints and is nursed back to health by Philip. They then discover that Priscilla's father had married a gypsy who gave birth to twin daughters, then ran off with Nora while Priscilla remained with her father. With the mystery solved, Philip and Priscilla marry.
