<P> Following the game's completion, the player is given one last challenge that will reward them with the original ending to the book . The original ending to the book, where Wargrave is the killer . Dying, he wants to mete out justice personally to criminals who have escaped punishment, who he has invited to the island . The alternate ending details the events of the book, And Then There Were None, wherein all the guests on the island are killed by Wargrave except for the last two, Vera and Lombard . Vera then shoots Lombard, thinking him the murderer (since Wargrave has faked his own death), and then hangs herself . Wargrave then shoots himself . </P> <P> And Then There Were None was announced on February 3, 2005, as the first in a series of games based on novels by Agatha Christie . For the release, The Adventure Company collaborated with developer AWE Productions . Lee Sheldon was named Lead Designer and writer for the game, while Scott Nixon, from AWE, was appointed Managing Director . The Adventure Company chose the novel And Then There Were None as the first game, instead of other Christie novels involving famous detectives Hercule Poirot and Miss Marple, for several reasons . Among them was the popularity of the novel, which would help with marketing; and the island nature of the story which would provide a natural barrier, while allowing more freedom of movement for the players within that confined area . </P> <P> One major obstacle in the development of And Then There Were None was gaining the approval of aspects of the game from Chorion, the company which owns the rights to Agatha Christie's works . The development team met with Mathew Prichard, Christie's grandson, and other members of Chorion . While protective of Christie's license, Chorion was quite open about changes to the plot, as long as they were within the style of Christie's novels . These included a change to the identity of the killer, the addition of a player character, and changes to the figurines at the table - renaming them "sailor boys", to fit in with the boat motif of being moored on the island . Chorion did not accept all the changes proposed by the developers, for example rejecting the idea of a one - man submarine the player could operate as not being in the style of Christie's work . The survival of Vera and Lombard, and the change of the General's name from MacArthur to MacKenzie, were both used by Christie herself in a 1943 stage adaption of the novel . Patrick Narracott as the eleventh character was a major plot change, and was done to explore a semi-romance between him and Vera Claythorne, as well as the developers' desire to have players connect to a more human character, rather than a nameless one . </P> <P> The main concern designer Lee Sheldon had was the emphasis placed on story and dialogue, he had considered the idea that the killer could change every time a player played the game; this idea of open - ended, modular gameplay was quickly discarded, as Sheldon thought it didn't pay homage to Christie's work . The orders of the murders forced Sheldon down a linear path, and the numerous cut scenes, cinematics and long dialogues were needed because the novel is composed largely of dialogue . Sheldon strived to make the puzzles a seamless part of the game's environment and plot, and not simply tacked on for the sake of a puzzle . </P>

Who the murderer in and then there were none
