I Am Mary Dunne is a novel, first published in 1968, by Northern Irish-Canadian writer Brian Moore about one day in the life of a beautiful and well-to-do 31-year-old Canadian woman living in New York City with her third husband, a successful playwright. Triggered by seemingly unimportant occurrences, the protagonist / first person narrator remembers her past in a series of flashbacks, which reveal her insecurities, her bad conscience concerning her first two husbands, and her fear that she is on the brink of insanity. I Am Mary Dunne has been described as "perhaps [Brian Moore's] best book". Robert Fulford, writing in Canada's The Globe and Mail, calls it "[a] feminist novel written before the wave of feminist novels began".In its original draft, I Am Mary Dunne was called A Woman of No Identity.
