What is the name of the title character of the John Fowler novel "The French Lieutenant's Woman"?

"The French Lieutenant's Woman" is a 1969 postmodern historical fiction novel by John Fowles. It was his third published novel, after "The Collector" (1963) and "The Magus" (1965). The novel explores the fraught relationship of gentleman and amateur naturalist Charles Smithson and Sarah Woodruff, the former governess and independent woman with whom he falls in love. The novel builds on Fowles' authority in Victorian literature, both following and critiquing many of the conventions of period novels.

Sarah Woodruff is the main protagonist according to the narrator. Formerly a governess, she becomes disgraced after an illicit, but unconsummated, liaison with an injured French naval merchant. The feminist critic Magali Cornier Michael argues that she is more a plot device, not interpretable as a main character because her thoughts and motivations are only interpreted from the perspective of outside male characters. Sarah offers a representation of myth or symbol within a male perspective on women.
