Runaway Pinkerton

When Matty’s high society parents grow tired of her refusal to pick a man and marry, they choose a potential husband for her. Matty has no intention of getting married, especially to the cold, boring man her parents have chosen. Matty wants adventures, to live a life of purpose, to be a Pinkerton agent like her grandfather. So she runs away from New York to St. Louis in a wild gamble for her freedom.
Cliff is leaving the Pinkerton Detective Agency, eager to return to ranching in western Montana. His days as an undercover agent are done. Well, once he completes one last job as a favor to the Chief. So Cliff takes a detour between Chicago and Montana via St. Louis, where he encounters a mysterious woman who disrupts a clandestine meeting with another agent. Something prompts Cliff to abduct the woman and drag her along on his last mission. There is no logical excuse for wanting to hang on to her after they meet, just a tugging at his heart warning him that if he walks away he will never see her again.
Both Cliff and Matty are running away from something. Matty is running away from a forced marriage and Cliff is running away from a terrible event in his past as a Pinkerton agent. Together they find something worth running to.
