Mystery Mania David Leithauser was published in Compute! Magazine December 1987. It creates logic puzzles with a murder mystery theme to them; 32000 variations with five levels of play to choose from. I've added a graphic title screen and made a few changes to make it more Sherlock Holmes like. For example, when you win, the level your win is recognized by being awarded different levels of the Order of the British Empire.
The game can be played at my GameJolt page:
Just select "Play Our Educational Game." Then select MYSTMANI and type RUN in the main emulator window. Thanks to Mike Tinnes for letting me use his emulator.
