Noel Streatfeild’s children’s classic Ballet Shoes, published in 1936, remains a favourite for anybody interested in theatre. Whenever one mentions a first-class book of this kind, if the adult addressed knows it, their face will light up, and they’ll look exactly as they must have done as a child. This is true of either sex. E. Nesbit’s name gets many nods and smiles, particularly from elderly gentlemen who remember the Psammead: ‘a little beast’, said one. Mention of Narnia produces endless discussions on the merits of the seven books. And every woman who discovered I was writing about Ballet Shoes responded in exactly the same way. A sharp intake of breath was followed by, ‘Oh! My favourite book!’
