Memoir From Scientology Leader's Dad May Be Due to Leah Remini 'His story is important' By Michael Harthorne, Newser Staff Posted Apr 28, 2016 5:38 PM CDT 74 comments Comments The cover of the book, “Ruthless: Scientology, My Son David Miscavige, and Me,” by author Ron Miscavige. (Courtesy St. Martin’s Press via AP) (Newser) – Actress Leah Remini, who knows a thing or two about Scientology memoirs, says she prompted the father of Church of Scientology leader David Miscavige to write his own memoir, which is slated to be published May 3, Us Magazine reports. "His story is important," Remini tells ABC News. "We're all gonna speak up. You're not gonna just bully people telling their stories." Ron Miscavige spent more than 40 years with the Church of Scientology—27 of them with Sea Org—before leaving in 2012. "I called him and I offered my support because I know he must've felt alone," Remini says. The church is attempting to block the publishing of Ruthless: Scientology, My Son David Miscavige, and Me, which it calls a "literary forgery" and blatant attempt to make money. In addition to the memoir, Ron Miscavige gave an exclusive interview to 20/20 scheduled to air Friday. In a preview published by ABC News, he says he was spied on by private investigators for two years after leaving the church. At one point, police contacted one of the PIs and found rifles, handguns, ammunition, and multiple license plates in his SUV. “It sounds like he’s a hitman, doesn’t it?” Miscavige asks 20/20. Police say one of the PIs was told by David Miscavige to "let him die" if Ron was to have any sort of medical emergency. Ron Miscavige says it felt like a "shot to the head" to hear his own son say that.
