She headed to the back of the store and found the solitary copy of "Who am I?" by Gilderoy Lockhart. Looking round until she could confirm that she was in fact alone she then opened the book to the first page. A key dropped to the floor at her feet, but she managed to catch the folded piece of letter stock. She knelt down to pick up the key. It was simple and nondescript. The only identifying mark as a small heart keychain that she thought was adorably punny.
