Mapleton, Colorado’s police chief, Gordon Hepler, would rather be on the streets than behind a desk, but he promised his late mentor he’d accept the position. And to Gordon, a promise is a promise, even if the person you made it to isn’t around anymore. However, doubts creep in, and he wonders if he was shoved into the job because his mentor thought he couldn’t cut it on the streets.
Everything changes when a fatal traffic accident well outside Mapleton seems connected to the elderly Rose and Sam Kretzer, two of Mapleton’s most beloved citizens. When Gordon ties the car accident to a grisly murder in Mapleton—the first anyone in town can remember—he’s afraid he’s into more than he bargained for.
The arrival of Megan, the Kretzers grown godchild, and Justin, their grandson, add to Gordon’s troubles when Megan is mugged and someone breaks in and ransacks the Kretzers’ home. Gordon’s fears that he’s in over his head are realized when his investigation seems to link the Kretzers to a Nazi war criminal. Can he work with the big-city detective brought in to assist? Will he be able to solve the crime without revealing the secrets of his citizens?
