Agatha Christie: and Then There Were None

Agatha Christie: And Then There Were None is the title of a 2005 point-and-click adventure game developed by AWE Productions and published by The Adventure Company for Microsoft Windows. It was the first in The Adventure Company's Agatha Christie series. The game is a detective murder-mystery; it begins with nine people, including Patrick Narracott, the playable character, who meet and journey to the fictional Shipwreck Island. There, two additional onscreen characters are introduced, and the story then follows the events that unfold.

And Then There Were None retains most of the basic plot elements of Agatha Christie's novel of the same name, with the major differences being the inclusion of the playable character, Patrick Narracott, and the creation of a range of possible endings. In order to further the connection between the game and its source material, Christie's novel is included in the North American release of the game.

Reactions to the game were mixed, with many reviewers polarized in their opinions: some calling it a good adaptation of the novel; others, an extremely poor adventure game. Several reviews harshly criticized the game's character design and graphics as being archaic and outdated, whereas others praised aspects such as character dialogue and an immersive story.

A Wii version of the game was released in February 2008. It features several motion-sensitive puzzles, made possible with use of the Wii Remote, in which the player must make a motion that most naturally corresponds to an assigned task. One of the puzzles from the PC version was cut.

Agatha Christie: And Then There Were None was followed by a second game, Agatha Christie: Murder on the Orient Express; also based on a Christie novel, but with a plot unrelated to that of the first game.
