"Shirlah Combes," William answered proudly. "Famous Muggle policeman. He was always one of my favourite historical figures; my parents used to read me the stories from his published biography. He was very clever. He would have been a Ravenclaw if he hadn't been a Muggle."
He touched his head worriedly. "You can't tell?" he asked. "Have you seen pictures of Combes? Because Mikey did the hat, and I think he did an excellent job. It's his official Muggle policeman hat, it's in all of the portraits."
