Not That Sort of Girl (1987) is a novel by British author Mary Wesley. The novel is set in Southern England and takes its beginning in the late 1930s and follows the life of Rose Peel throughout 48 years of marriage.
At the age of 19 Rose is in love with the passionate but penniless Mylo Cooper but agrees to marry Ned Peel. She doesn't love Ned, but it's the safe thing to do. Ned has inherited a country house called Slepe from an uncle, and the married couple move in shortly after the wedding. Rose immediately falls in love with the house and its garden, if not with its owner. During the war Ned is away from the house a lot and her real love, Mylo, starts visiting her at Slepe. They go on meeting each other secretly through all 48 years of Rose's marriage until her husband's death.
Shortly after Ned dies, Rose leaves Slepe, her beloved home for half a century (now her son's and not so beloved daughter-in-law's), taking only a few things with her. Temporaril
