In the event he was obliged to create new schools such as Carcroft and Sparshott, as well as trying the romance genre under the name of Winston Cardew. By 1946, however, he had received permission to write Greyfriars stories again, and obtained a contract from publishers Charles Skilton for a hardback series, the first volume of which, "Billy Bunter of Greyfriars School", was published in September 1947. The series was to continue for the rest of his life, the publisher later changing to Cassells. In addition, he wrote further St Jim's, Rookwood and Cliff House stories, as well as the television scripts for seven series of Billy Bunter stories for the BBC.
