We have London's blue plaques on the Post this week. Or, rather, blue plaques which are not there but we feel should be. Several of our authors do have plaques (eg Winifred Holtby, Katherine Mansfield), but why, for example, does Noel Streatfeild (above) not? She went to RADA, set Ballet Shoes (1936) in a house on the Cromwell Road where she lived, and 'lived a busy London literary life'. In addition to her novels for adults, her contribution to children's literature is immeasurable, and deserves recognition.
