Fifty years after Calvin Coolidge's death, Leonard Hemmings, the late president's greatest fan and impersonator, has been murdered. Detective Sergeant Natalie Dvorak of the Vermont State Police must find out why the kindly grandfather was targeted and by whom. Complicating the investigation is Natalie's ex-husband, back in her life after many years for a not-so-happy reunion. Meanwhile, Natalie deals with the pressures of being a supportive wife, a responsible stepmother, and a caring aunt. A suspected conspiracy reaches into both Natalie's work and family lives as she draws nearer to solving the case.
