Jack Lime, amateur private eye, solves mysteries for his high school classmates in exchange for future favors. He stops at nothing — except for an occasional bout of narcolepsy — to crack three seemingly standalone cases while dodging bullies, Principal Snit and tireless reporter KC Stone. In the tradition of 1950s noir but with a thoroughly modern hero, these stories — shot through with Lime's acid wit — are best served with a root beer float.
