Stiles Long and Michael O’Leary were asked to join two agents from the Secret Service to break up a counterfeiting ring. They didn’t usually work with other agents, but since several Secret Service agents had been killed, the president wanted the Pinkertons in on the job.

Reginald McCullough did not want to be anywhere near his uncle, but this was a chance for him to move up in the ranks. His new partner, Rochelle Warner, was a stranger, but he’d do whatever it took to do a good job. When he entered his uncle’s office in St. Louis, he was shocked to see his old lover, Michael O’Leary there as well.

The assignment would take them on a new Pullman train across several states and cities. Death seemed to be at every turn. Stiles, Michael, Reginald, and Rochelle; all had attempts made on their lives. Every clue seemed to lead to a dead end.

Could Reginald pull Michael away from Stiles?  Could they discover who the head of the counterfeit ring was before the end of the line in Santa Barbara, or would they end up just another dead agent riding the Death Train?
