The clue

The Clue! (known as Der Clou! in Austria) is a remake of the 1986 game They Stole a Million. It would form a two-game series, with a sequel following in 2001, under the guise of The Sting! or Der Clou 2!. In 2000 the source code was released to the public. The game was since then ported to modern platforms (Windows, Linux) via SDL and receives still updates by the game's community (2015).

An adventure game, assuming the identity of Matt Stuvysant, a burglar who is looking beyond just the clothes on his back and a hotel room on Holland Street, the player is tasked with finding accomplices, scouting potential targets, and plotting plans of burglary, down to the finest detail. Featuring the archetypal point-and-click interface during investigations, engaging in planning a job would alter the controls to include keyboard, using it to control the planned movements of the personnel.
