Tuesday, Doug is joined by Pulitzer prize-winning author Lawrence Wright whose latest book investigates the Church of Scientology. Wright says that he's fascinated by why people would be drawn to what he's called "the most stigmatized religion in America." Over the course of three years, Wright sat down with more than 200 current and former members to get at that question. The result is an exhaustive look at the history and the inner workings of Scientology. His book is called Going Clear: Scientology, Hollywood, and the Prison of Belief

Lawrence Wright is an author, screenwriter, playwright, and a staff writer for The New Yorker magazine. Among his other books is The Looming Tower: Al-Qaeda and the Road to 9/11, which earned him the 2007 Pulitzer Prize for General Nonfiction.
