From Wikipedia:
Find your way through a run-down, foreboding mansion in order to find various treasures, solve a murder, sleep with the maid (if very lucky), and avoid getting "killed" in the process all before the mansion is destroyed by fire at midnight to end the game. In addition to the 3 rooms x 3 rooms x 3 stories cube-shaped mansion, there are gardens, tunnels, nefarious characters, and other obstacles to make one's way through or around.
The exact release/creation date for this program is unknown. The Renga in Blue blog examines some of the evidence and suggests the date of 1978 is most likely.
Originally written for the HP1000 running RTE and ported to HP3000 running MPE. A C port exists.
