A 1975 board game by Gammon Games. A game card is drawn to select what Adventure of Sherlock Holmes is being played. A short story is read off the card to all the players setting up the Adventure. The players roll dice moving a token around a board depicting an abstract map of Holmes' London. When a player lands on one of several special locations a clue number is read off of the game card and found in an index within a clue book. The clue is read by that player alone. When a player has gathered enough information to make a stab at solving the Adventure they must move their token back to 221b Baker Street and procalim the answer.

The game comes with a few dozen Adventures to solve. After those are solved the replay value plummets rapidly.
