Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.Mary Elizabeth Braddon (4 October 1835 - 4 February 1915) was an English popular novelist of the Victorian era.She is best known for her 1862 sensation novel Lady Audley's Secret.Born in London, Mary Elizabeth Braddon was privately educated. Her mother Fanny separated from her father Henry in 1840, when Mary was five. When Mary was ten years old, her brother Edward Braddon left for India and later Australia, where he became Premier of Tasmania. Mary worked as an actress for three years in order to support herself and her mother. In 1860, Mary met John Maxwell (1824-1895), a publisher of periodicals. She started living with him in 1861.[2] However, Maxwell was already married with five children, and his wife was living in an asylum in Ireland. Mary acted as stepmother to his children until 1874, when Maxwell's wife died and they were able to get married. She had six children by him, including the novelist William Babington Maxwell. Braddon was a prolific writer, producing more than 80 novels with inventive plots. The most famous is Lady Audley's Secret (1862), which won her recognition, and a fortune as a bestseller. It has remained in print since its publication and been dramatised and filmed several times. R. D. Blackmore's anonymous sensation novel Clara Vaughan (1864) was wrongly attributed to her by some critics.
