Revealed: John Lennon Feared For His Life

According to a recently released memo he wrote to his personal assistant, John Lennon already had notions of a possible threat on his life, months before he was murdered.

"Explain to me why we are sleeping here with a front door that any nut can open (it doesn't lock)," he wrote in the note dated April 28, 1980. "People know I'm here- gardeners, painters, etc."

His anxiety and frustration is clearly evident in his agitated ending directive to assistant Fred Seaman: "You're usually last in at nite you better check."
