Dear Enemy is the sequel to Jean Webster's novel Daddy-Long-Legs. First published in 1915, it was among the top ten best sellers in the US in 1916. The story is presented in a series of letters written by Sallie McBride, Judy Abbott's classmate and best friend in Daddy-Long-Legs.
Among the recipients of the letters are Judy; Jervis Pendleton, Judy's husband and the president of the orphanage where Sallie is filling in until a new superintendent can be installed; Gordon Hallock, a wealthy Congressman and Sallie's later fiancé; and the orphanage's doctor, embittered Scotsman Robin 'Sandy' MacRae (to whom Sallie addresses her letters: "Dear Enemy").
Webster employs the epistolary structure to good effect; Sallie's choices of what to recount to each of her correspondents reveal a lot about her relationships with them.
Jean Webster was the pen name of Alice Jane Chandler Webster (July 24, 1876 – June 11, 1916), an American author whose books include Daddy-Long-Legs and Dear Enemy. Her best-known books feature lively and likeable young female protagonists who come of age intellectually, morally, and socially, but with enough humor, snappy dialogue, and gently biting social commentary to make her books palatable and enjoyable to contemporary readers.
