The
player moves around London via an elaborate overview map. Additional locations become available when Holmes finds additional leads. In each location, the player can select nine different
verbal options to interact with objects or people. When accessing the inventory menu, the player has three different verbal actions to manipulate any
items Holmes has picked up. When talking to people, Holmes has different dialogue options to gain information or try to get their cooperation. Dr. Watson can give his views, which may serve as puzzle hints. He may even help Holmes to perform an action he cannot do alone. Dr. Watson's journal also references the events in the gameplay. The graphics are
VGA, with
MIDI music and a few scenes with digitalized speech (in the intro and end sequence, and the
cutscene at St Pancras Station. In the other scenes there are sound effects, but no speech). The player interacts with the characters through a command menu with verb icons that is intuitive for anyone who had played other adventure games of the period. The
3DO version consists of full voiced dialogue and the portraits of the talkers were replaced by
clips with filmed actors, but also drops Dr. Watson's journal feature. In the video clips in the 3DO version, Sherlock Holmes was played by David Ian Davies, and Dr. Watson was played by
Laurie Main. ==Reception==
