"I'm going to steal the Declaration of Independence." This was the iconic line delivered in the 2004 movie National Treasure, which celebrates its 20th anniversary this year. Aubrey Paris and Emily Black, hosts of the hit National Treasure Hunt podcast, break down the film's history, science, ciphers, and movie magic in their debut book, National Treasure Hunt: One Step Short of Crazy. Now they're visiting Baltimore County Public Library, Essex Branch, for a 20th anniversary screening of the film, followed by a Q&A session and book signing.
