HAVING read the letters relating to Mrs Dingwall, there is a book called Horsewoman: The Extraordinary Mrs D, a biography of Louie Dingwall, Dorset’s racehorse trainer by Alan R. Bennett with a foreword by Brough Scott and was first published in 1979 by Dorset Publishing Company. My copy is signed by the author and also Mrs D.
