Moonmist

Moonmist is an interactive fiction computer game written by Stu Galley and Jim Lawrence and published by Infocom in 1986. The game was released simultaneously for many platforms, including the IBM PC, Apple II, Amiga, Atari ST and Commodore 64, and is Infocom's twenty-second game. Galley and Lawrence had previously written Seastalker for Infocom. The character is a young detective who is asked by his girlfriend Tamara Lynd to investigate her new home, Tresyllian Castle in Cornwall, England. Tamara has recently become engaged to the lord of the castle, Jack Tresyllian. She was very happy until she started seeing the White Lady, a ghost that has supposedly haunted the castle for centuries. As if seeing a ghost wasn't nerve-wracking enough, she begins to fear for her life. Is Tamara's imagination just overactive because she lives in a big old castle, or is someone really trying to kill her? And if her life is in danger, is it a ghost or someone using it as a disguise?
