As she lies dying, she gives Helen a letter of introduction to a man she was to have married in the East, urging her to leave Nugget City.

Helen goes East and learns that Taylor is the man whom Myrtle was to have married, but because she immediately falls in love with him, she conceals her own identity and masquerades as Myrtle.
