After suffering several minor nuisances, the Southern Pacific Railroad hires the J&K Agency to uncover the identity of the vandals before they hurt a passenger or crew member. J&K Agency partners Fremont Jones and Michael "Archer" Kossoff catch the Chicago-bound train in San Francisco. On the train, the lovers pretend to meet for the first on the train and to flirt with one another. However, the vandals devastate the plan when they blow up a railroad bridge east of Salt Lake City that derails the train, killing many and severely injuring numerous other people. Michael suffers a broken collar bone and the shock that Fremont has vanished without a trace.
Melancthon Pratt rescues Fremont, who suffers a severe head trauma and two broken legs. However, the pious Mormon also abducts his patient because he decides she will become wife number six. As Fremont tries to figure out how to escape, Michael desperately searches for her even as Melancthon plans their wedding.
DEATH TRAIN TO BOSTON is a refreshing Fremont Jones historical mystery that will send readers searching for the previous best selling novels. The story line is interesting as the chapters alternate between what is happening to Fremont and Michael's frantic quest to find her. A lesser talent than the delightful Dianne Day would leave readers totally confused, but the awesome author turns the book into two rotating subplots that cleverly tie back into a fabulous story. Though already the fifth story in this series, Fremont and Michael retain their originality. The secondary players, especially Melancthon and his spouses provide readers with a feel for the era. Fans of historical mystery will want to catch this entertaining tale.
