First Frost: A Longmire Mystery

Extended Synopsis

Past and future collide with gripping intensity in First Frost, the milestone twentieth volume of Craig Johnson’s bestselling mystery series. The novel employs a propulsive dual-timeline structure that catches Sheriff Walt Longmire at two defining thresholds of his life, matching the raw vulnerability of youth against the hard-earned stakes of his modern career. Moving seamlessly between the turbulent geopolitical shifts of the mid-1960s and the explosive fallout of modern-day frontier law enforcement, Johnson delivers a thorough examination of the choices that forge an American icon.

In the summer of 1964, recent college graduates Walt Longmire and Henry Standing Bear recognize the inevitability of the draft and enlist to serve in the Vietnam War. While catching a few final waves on the California coast before reporting for duty, they witness a sudden storm capsize a nearby cargo vessel. Springing into action, the former college football players pull survivors ashore, only to discover from arriving police that the vessel was trafficking illicit underground contraband. Deciding to put the incident behind them, the duo hits Route 66, but the dangerous consequences of the shipwreck tail them down the highway, threatening to derail their futures before their military service even begins.

In the present day, the narrative picks up immediately following the fatal, multi-generational conspiracy exposed in The Longmire Defense. Sheriff Longmire finds himself pulled from the field and forced to defend his actions before a judge. With powerful, hidden adversaries orchestrating a retaliatory campaign behind the scenes, the sheriff of Absaroka County must carefully calculate his next moves if he hopes to survive the legal crossfire and finish the fight he started. Standing between law and anarchy, compassion and cruelty, Walt must confront the ghosts of 1964 to preserve his present-day survival.
