The Trail of the Shadow(1917)

Sylvia Mason, a mysterious girl, lives in a cabin by herself and sells her bead work to the visitors at a large hotel nearby. At the hotel, Sylvia meets Easterner Henry Hilliard, who falls in love with her, but she refuses to marry him and will not explain her reasons. Thus Henry returns East without learning that Sylvia's father had been murdered by his private secretary Jack Leslie in revenge for her refusal to marry him. One night after Henry's departure, Leslie, now known as the outlaw "The Shadow", breaks into Sylvia's cabin. There is a struggle that leaves Sylvia unconscious, and when she awakens she finds a note claiming that because Leslie has violated her, she must marry him.
