221B Baker Street is a solid computer version of an underrated board game of the same name, which is similar to Clue! but with more challenging cases and innovations that evoke the feel of Holmesian London. As in the classic board game, up to 4 players first choose their alter egos from main characters in the classic series, including Holmes himself. Players then take turns travel through Victorian London gathering clues and solving mini-mysteries such as The Coded Message, The Clerk’s Demise, and The Nettlesome Bride.
