The End Of The Affair is based upon the classic novel by Graham Greene. Writer Maurice Bendrix (Ralph Fiennes) discovers that his friend, Henry Miles (Stephen Rea), is convinced that his wife, Sarah (Julianne Moore), is having an affair. This does not come as a surprise to Bendrix as he himself had an affair with Sarah during the war. Jealous that she appears to have found a new lover to supercede him, he employs a private detective to get to the truth of whether she is being unfaithful to her husband, beginning a course of events that will eventually lead to a tragic outcome.
