Celebrity biographer Charles Higham, who wrote about the lives of Lucille Ball, Errol Flynn, Katharine Hepburn, Howard Hughes and others, has died in Los Angeles at age 81.
Friend Todd McCarthy tells the Los Angeles Times that Higham died of an apparent heart attack April 21 at his home.
Higham was the author of dozens of biographies, many of them sensational books detailing political and sexual intrigue.
In 1980's Errol Flynn: The Untold Story, Higham wrote that the matinee idol was a Nazi spy.
Flynn's ex-wife, Nora Eddington Black, denounced the allegation, saying Higham lacked documented proof.
Higham defended the book, but he told The New York Times he had no documents saying Flynn was a Nazi agent.
