Meursault leads an apparently unremarkable bachelor life in Algiers until he commits a random act of violence. His lack of emotion and failure to show remorse only serve to increase his guilt in the eyes of the law, and challenges the fundamental values of society - a set of rules so binding that any person breaking them is condemned as an outsider. For Meursault, this is an insult to his reason and a betrayal of his hopes; for Camus it encapsulates the absurdity of life.

In The Outsider (1942), his classic existentialist novel, Camus explores the predicament of the individual who refuses to pretend and is prepared to face the indifference of the universe, courageously and alone.
