Mortville Manor (French: Le Manoir de Mortevielle) is a point-and-click adventure game developed and published by Lankhor released in 1987 for Atari ST.

[2] The plot begins in the office of Jérôme Lange, a famous private detective, who receives a letter from his childhood friend Julia Defranck, in which she writes that she is ill and asks him to investigate strange events at Mortville Manor.

The first version of Mortville Manor was released for the Sinclair QL and was developed by two employees of the Kyilkhor studio who operated with the Pyramide publishing house Bruno Gourier and Bernard Grelaud.

With its technical qualities and attractive price, the Atari ST was gaining momentum in France and the company decides to develop for this machine as a priority.

[10] Eric See-To for New Straits Times wrote that the game was a "fairly absorbing adventure", calling it unique, while criticizing the graphics and stating it was difficult to hear the digitised speech.
