The game has you controlling Sherlock and dear trusted associate Dr. Watson at certain points in an attempt to solve the mystery surrounding a murder. Valuing collecting information above anything else, all conversations are logged in a notebook along with points of note that you’ve spotted on the way. Unlike most other adventure games, you may only progress through the game when you have collected all of the evidence in an area. This can range from interviewing all suspects and asking all possible questions to a pixel hunting style search around every location for anything suspicious.
