Brian Epstein, former manager of The Beatles, engaged in homosexual acts with one of the band a sensational new book is set to claim.

The book, by former Epstein aide Joanne Peterson, will expose “revelations of Intimacy” with at least one of the legendary quartet, but until its release she refuses to reveal which one. Epstein died of an overdose in 1967 and it is well known that he had a crush on John Lennon, leading many to believe he is the mystery lover reports Breakingnews.ie.

The book has a working title of ‘There’s a Beatle in my closet’. Peterson explains: "I didn't tell people I worked for Brian because I didn't want to spend my time talking about the whole thing. But I was persuaded to talk at a Beatles convention a few years ago.”

"Afterwards, people kept saying, 'That was fabulous - we'd love to read about this’. Now I'm not far from finishing the book." She added.

As yet there is no release date for the book, but with such sensational claims involved it is expected to be a best seller.
