The Crimson Rooms is set in post World War I London, England in the year 1924. Evelyn Gifford is haunted by the death of her cherished brother James, who died in the Great War. Evelyn is stunned when a young woman named Meredith and her 6 year old son Edmund show up on the families doorstep. Meredith who is a nurse, claims that Edmund , conceived in a battlefield hospital, is the son of her brother James. The family take Meredith and Edmund in but they are still grief stricken from James death as well as the recent death of Evelyn's father. Evelyn is 30 years old, unmarried and lives with her mother, grandmother and Aunt Prudence and supports her family. This is quite unusual as Evelyn is one of few female lawyers and is struggling in a field that is dominated by men and a society that is not accepting of female lawyers. Most women of this time do not attend college and have their own careers. They are to focus on finding a husband and starting a family.
