What to Expect

Players take the role of investigators following clues from previously unpublished Watson diaries. The game mixes Deduction with Bluffing as you visit locations on a modular board to collect evidence. New adventures add special rules and challenges, and sessions can be played cooperatively, competitively, in teams, or solo.

Who Is This Game For?

Aimed at fans of deduction and the Sherlock Holmes setting, suitable for seasoned players and groups willing to invest about 90 minutes. The range from solo to seven players makes it flexible for different table sizes. Some prior experience with deduction or bluffing games is helpful.

How It Works

Deduction is the core mechanism, augmented by Auction / Bidding and Variable Player Powers. The modular board changes the investigation layout each game, auctions create tactical contests for clues or actions, and variable powers make player roles asymmetric. Together these mechanics drive decision-making and replayability.
