Chicago, 1889. "Find her" is the only instruction that private detective Cobb Bridger receives from Andrew Charles Mackey III. The scion of a wealthy Chicago family, Mackey is desperate to know the whereabouts of the woman who disappeared from his employ, taking with her something of great value. Intrigued as much by what Mackey won't say about the missing item as he is by Mackey's description of the missing woman, Cobb accepts the assignment. Bitter Springs, Wyoming, has a new schoolteacher who may or may not be exactly what she seems. But upon making the acquaintance of Miss Tru Morrow, Cobb begins to question the guilt of this golden-haired lady.
