Massingham is not the only super fan. Tracey Nicol-Lewis, 43, and her 15-year-old son Brenden like to dress up in Hogwarts uniform for trips to the supermarket in Cardiff, Wales. Nicol-Lewis' obsession with Rowling's world of wizards started when her husband gave her one of the books, "Goblet of Fire," shortly before he died. "We kind of clung to that," she said. She has since spent around 40,000 pounds ($50,600) on all things Harry Potter, putting together a collection of 2,506 pieces of memorabilia.
