GUMSHOE One-2-One is a system for designing and playing investigative roleplaying games and adventures for one player and one Game Moderator (GM). Together, you create a story that evokes the classic solo protagonist mystery format.

In a GUMSHOE One-2-One game, the player character discovers something which triggers their investigation, and then the (GM) guides them through a number of scenes, during which they use their Investigative Abilities to gather the core clues they need to move the narrative forward. They must then put the clues together to uncover the secrets behind the mystery.
