who was killer in and then there were none
And Then There Were None 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.
