Sherlock Holmes: Consulting Detective is an FMV adventure game and one of the first of its kind, as well as a very early CD-ROM game. It was released on PC DOS, Mac, Sega CD and TurboGrafx-CD in the early 1990s, and later saw an interactive DVD release in 1999.
The game follows Sir Arthur Conan Doyle's famous sleuth on three separate mysteries. Each is introduced with full-motion video and then moves to a menu-driven prompt that allows the player to investigate crime scenes, listen out for rumors and send out the Baker Street Irregulars - a group of street urchins Holmes befriends in the books - to discover what they can.
The game was followed by two sequels. The first of these sequels (Sherlock Holmes: Consulting Detective Volume II) also saw Sega CD and TurboGrafx-CD releases, but the second (Sherlock Holmes: Consulting Detective Volume III) was exclusive to computers. The three games were also packaged together in a compilation.
