I have always thought that The Eagle of the Ninth (published in 1954) was the first book of Rosemary Sutcliff’s to be turned into a serial on Children’s Hour on BBC Radio. But it wasn’t! It was Brother Dusty Feet (published in 1952) which was billed as ‘A Chronicle of the Road by Rosemary Sutcliff’ in the Radio Times. I learn this from a website I have come across which is new to me—the BBC Genome project, which contains the listings information which the BBC printed in Radio Times between 1923 and 2009. You can search the site for BBC programmes, people, dates and Radio Times editions.
