Two impoverished children, Edred and Elfrida Arden, inherit the decrepit Arden Castle and search for the lost family fortune that will allow them to rebuild it. With the assistance of the magical Mouldiwarp, they travel back in time to earlier periods of English history, searching for clues.... Edith Nesbit (married name Edith Bland; 15 August 1858 - 4 May 1924) was an English author and poet; she published her books for children under the name of E. Nesbit. She wrote or collaborated on more than 60 books of children's literature. She was also a political activist and co-founded the Fabian Society, a socialist organisation later affiliated to the Labour Party. Nesbit was born in 1858 at 38 Lower Kennington Lane in Kennington, Surrey (now part of Greater London), the daughter of an agricultural chemist, John Collis Nesbit, who died in March 1862, before her fourth birthday. Her sister Mary's ill health meant that the family travelled around for some years, living variously in Brighton, Buckinghamshire, France (Dieppe, Rouen, Paris, Tours, Poitiers, Angoulême, Bordeaux, Arcachon, Pau, Bagnères-de-Bigorre, and Dinan in Brittany), Spain and Germany, before settling for three years at Halstead Hall in Halstead in north-west Kent, a location which later inspired The Railway Children (this distinction has also been claimed by the Derbyshire town of New Mills). At eighteen, Nesbit met the bank clerk Hubert Bland in 1877. Seven months pregnant, she married Bland on 22 April 1880, though she did not immediately live with him, as Bland initially continued to live with his mother. Their marriage was a stormy one. Early on Nesbit discovered that another woman believed she was Hubert's fiancee and had also borne him a child. A more serious blow came later when she discovered that her good friend, Alice Hoatson, was pregnant with Hubert's child. She had previously agreed to adopt Hoatson's child and allow Hoatson to live with her as their housekeeper. After she discovered the truth, they quarrelled violently and she suggested that Hoatson and the baby should leave; her husband threatened to leave Edith if she disowned the baby and its mother. Hoatson remained with them as a housekeeper and secretary and became pregnant by Bland again 13 years later. Edith again adopted Hoatson's child. Nesbit's children were Paul Bland (1880-1940), to whom The Railway Children was dedicated; Iris Bland (1881-1950s); Fabian Bland (1885-1900); Rosamund Bland (1886-1950), to whom The Book of Dragons was dedicated; and John Bland (1898-1971) to whom The House of Arden was dedicated. Her son Fabian died aged 15 after a tonsil operation; Nesbit dedicated a number of books to him: Five Children and It and its sequels, as well as The Story of the Treasure Seekers and its sequels. Nesbit's adopted daughter Rosamund collaborated with her on the book Cat Tales....
