<Dt> Postscript from the Killer </Dt> <P> In a postscript, a fishing ship picks up a bottle inside its trawling nets; the bottle contains a written confession of the killings, which is then sent to Scotland Yard . It is not clear how long after the killings the bottle was discovered . </P> <P> In the confession, Justice Wargrave writes that he has long wished to set an unsolvable puzzle of murder . His victims would be of his choosing, as they were not found guilty in a trial . He explains how he tricked Dr Armstrong into helping him fake his own death under the pretext that it would help the group identify the killer . He also explains that he replaced the chair in Vera's room . Finally, he reveals how he used the gun and some elastic to ensure his own death matched the account in the guests' diaries . Although he wished to create an unsolvable mystery, he acknowledges in the missive a "pitiful human need" for recognition, hence the confession . </P> <P> He describes how his first victim was Isaac Morris, the sleazy lawyer and drugs trafficker who anonymously purchased the island and arranged the invitations on his behalf, making nine murders and two suicides. Morris was poisoned before Wargrave departed for the island . Wargrave's intention is to stymie the police as to which person on the island was the murderer . He states that, although there are three clues that could guide the police to the correct killer, he is confident they will be unable to find them and that the mystery will remain unsolved until the confession is read . </P>

Who was the murderer and then there were none
