Elma Mary Williams (1913–1971)

"Elma Williams always loved the countryside and always wanted to write. Pant Glas and Valley of Animals are the inevitable result. But Miss Williams also has several successful thrillers and romances to her credit, and, before settling in Wales, ran her own secretarial service and travelled in Tanganyika. At present she is plotting the progress of a new member of the family - a small pink pig called Bumble."
