T. I. S. "Tizzy" Harrison is the Children's Book Editor at Hamilton Press and a friend of Selina Gascoigne. In Susan Rushes In, Midge writes a story called The Greedy Dragon and Charlotte adds illustrations to it. At Mrs. Gascoigne's suggestion, Charlotte submits The Greedy Dragon to Hamilton Press using the pen name of Marjorie Charlotte Carmichael. Mr. Harrison buys the story for ten guineas. He also expresses interest in any other stories about the same dragon, believing that it would be possible to build a small series.
