The Calendar Man

A story roleplaying game about a serial killer whose crimes challenge police, journalists, and other investigators. Players portray disparate characters confronting disturbing evidence, personal isolation, and questionable investigative methods as the case unfolds. The game uses vignettes, interrogations, interludes, and ensemble scenes to build a shared narrative without a dedicated game master. It requires no preparation and supports three or more players, using a poker deck and tokens to track drama points. Game length increases with the number of players and assumes familiarity with scene framing and shared authority.
