Mortville Manor is an adventure based within a large house in France, where you play the role of the great detective, Jérôme Lange and have been invited to stay, only to find yourself in the middle of a mystery.

The scenario has a lot of atmosphere, although there are limited descriptions for each location - instead you have to rely on the pictures which are drawn and the interaction with other people around the house, if you are to solve the mystery.

The range of commands is more limited than normal, as this is supposed to be more interactive than a normal text adventure. For example, enter the command OPEN and a small cursor appears on the screen for you to move and indicate which object you wish to open.

A challenging puzzle, this proved a great hit and later versions were  released for the Atari ST computer (with speech generation), the Amstrad CPC, Commodore Amiga and DOS.
