Enter and explore an inherited mansion. Deal with the inhabitants and find the two parts of the treasure.
After finding the first part of the treasure you enter a Master's Game where the save-game feature is removed and a limit placed on the number of moves you may make.
Notes
The date of publication of this game is unclear; with sites split between 1980 and 1981. The games does appear in the HCS "November 1980" catalogue, but references to the game only appear in magazines from early 1981.
At first I think it was another clone of Mystery House, but I find it really fun, and the master part is weird but more fun than the first part.
A good game for 1981.
