In Search of the Unknown is a module for the Dungeons & Dragons roleplaying game, designed for use with the Basic Set of rules. It was written by game designer Mike Carr and was first published in 1978 by TSR, Inc. The module details a hidden complex known as the Caverns of Quasqueton. Reviewers considered it a good quality introduction to the game that was written in the so-called dungeon crawl style, where the primary goal of the players is the exploration of a dangerous labyrinth to battle monsters and obtain treasure.
