<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, but is morally limited to victims who are themselves guilty and deserving of such an end . He explains how he tricked the gullible Dr. Armstrong into helping him fake his own death under the pretext that it would supposedly give him the freedom to help the group identify the killer, and also explains that after Vera died, he replaced the chair in her room neatly against the wall . 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 also describes how his first chronological victim was actually Isaac Morris, the sleazy lawyer and drugs trafficker who anonymously purchased the island and arranged the invitations on his behalf . Morris was poisoned before Wargrave departed for the island . Wargrave's intention is that when the police arrive they will find ten bodies, with evidence that someone had been alive after each death, but nobody else on the island, and no way to trace the killer through his invitations or preparations . 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 do so and that the mystery will remain unsolved until the confession is retrieved . </P>
