Jack Frost is a gritty, dogged and unconventional detective with sympathy for the underdog and an instinct for moral justice who attracts trouble like a magnet. Despite some animosity with his superintendent, Norman “Horn-rimmed Harry” Mullett, Frost and his ever-changing roster of assistants manage to solve cases via his clever mind, good heart, and cool touch.
