This solo supplement is intended to compliment Brindlewood Bay by Jason Cordova and The Gauntlet.
What it adds to the game are tools for creating random mysteries, suspects, clues, and void clues.
You also get an Oracle that works like any other move, with positive and negative outcomes replacing hits and misses.
Alongside the core solo rules, you also get advice on solo playing the Murder Mavens, describing scenes and using all the individual tools.
