Michael Jackson may be gone, but the questions he left unanswered about his mysterious life have not been forgotten. In Touch has learned exclusive details about an explosive new tell-all book about Michael’s controversial behavior. The most sensational claim in Unmasked: The Final Years of Michael Jackson by Ian Halperin, due out this month, is that Michael was not a pedophile. “The book claims that Michael was innocent of the molestation charges and a victim of extortion,” an insider who has read the book tells In Touch. “This is what led to the heavy drug abuse and everything that followed.”
