The Mechanicsburg Mystery Bookshop in Mechanicsburg, Pa., held a dual fête on Saturday that honored both Nancy Drew, who turned 80 this year, and the store's 20th anniversary. "I don't know who had more fun... the customers or me," said owner Debbie Beamer, who gave a talk and slide show about the fictional heroine. Both grown-ups and kids were entertained with a screening of one of the first Nancy Drew movies, a quiz with prizes, a cardboard cut-out of Nancy Drew for photo ops and a custom-made cake to feast on. Aspiring sleuths were given "Nancy Drew Detecting Kits" with a magnifying glass, a notepad and pen, a flashlight keychain and chocolates. "We had an absolute ball," Beamer said. "I think every girl wants to grow up to be Nancy Drew."
