"Cranston Manor" is a 1981 adventure game by Harold DeWitz and Ken Williams, and published by On-Line Systems. It runs on any Apple ][ with 48K.

Description from Mobygames:

Cranston Manor is the fourth game in On-Line System's Hi-Res Adventures series, along with Mystery House, The Wizard and the Princess, and Mission Asteroid. In the game, you must invade a mansion that was occupied by a late millionaire and steal the sixteen treasures that lie in it. You perform actions in the game by only typing a one- or two-word command (e.g. "west", "get shovel", etc.), and you can save the game at any point in the game by inserting a disk and pressing a letter.

Cranston Manor was based on the original text adventure, The Cranston Manor Adventure, by Larry Ledden.
