Ten Little Indians

Number 10 in the Mysterious Adventures series of interactive fiction is inspired by the Agatha Christie book "And Then There were None". The player's aim is to find the gold statue, formed by Major Johnstone-Smythe from most of his assets shortly before his death. The Major also made 10 worthless copies in various colours, and hid them in and around his mansion. Only the 10 'little indian' figurines, assembled together, would reveal the location of the final golden one. These figurines are hidden behind and under ordinary household objects, and in various hiding places. The game begins in a train carriage and the player's first task is to prevent the train from crashing, which must be achieved in a limited number of moves. Once this has been achieved the train arrives at Lower Massington station and the player must then find their way to the Major's mansion in Upper Massington.

Around this time, Scott Adams' game engine was redone to allow complete sentences instead of the more primitive 2-word input that had been used previously. Brian Howarth gained the chance to use this in the Mysterious Adventures games, although early versions of the game may have still used the cruder parser.
