French Lieutenant’s Woman written by John Fowles mainly talks about the developing relationship between Sarah Woodruff and Charles Smithson.Sarah Woodruff known as“Tragedy”,or“The French Lieutenant’s Woman” is caught between the Victorian and modern ages.Rumors spread around that she stands by the sea to wait for the French Lieutenant who seduced her to return.And Charles is a young,lazy but intelligent English gentleman,who breaks off his engagement to a traditional young woman Tina to pursue Sarah.The novel is very special and attractive in many ways,so my purpose of the paper is to analyze how characters’ desire and postmodern environment wind through the story.
