who was the murderer in and then there were none
Agatha Christie: And Then There Were None 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.
Ordeal by Innocence The killer is revealed to be Kirsten Lindstrom, the Argyles' middle-aged housekeeper. Jacko had persuaded the plain Kirsten that he was in love with her, and persuaded her to murder his adoptive mother under cover of a "foolproof" alibi to steal some much needed money. But once Kirsten learned that Jacko was secretly married, she decided not to cover for Jacko, abandoning him to his fate.
