Born in 1929 in Orpington, Kent, Margaret Biggs was the daughter of a local Sales Manager for Chivers. Her family moved to Barnet, in Hertfordshire, in 1935, where she attended Queen Elizabeth’s Grammar School until 1946. When she left school, she went to work for the editorial department of the Evans Brothers publishing company, in Bloomsbury. She married David Cadney in 1953, and moved with him to Finchley, and then (in the 1960s) to Solihull, in the West Midlands, where she still lives today. She has one daughter and two sons. The author of a number of popular and collectible girls' school stories, Margaret Biggs is probably best known for her Melling School series, which is set at a weekly boarding school and is unusual, in that it shows boarding school life and home life side by side. The interaction between girls and boys is also atypical of the genre at that time.
