New York, Feb 13 : Former heavyweight boxing champion Mike Tyson is all set to send his memoir for publication, and is leaving no stones unturned to avoid any leaks.

He has made it a point that only five publishers see his book proposal, according to reports.

"It is similar to the way the Kurt Cobain journals were sold, which went for 4 million dollars," the New York Post quoted a source as saying.

"Just eight people were invited down to the Inn on Irving Place to view Kurt''s actual journals and hear his unreleased song.

"The book went on to be a No. 1 best-seller," the source added.

Tyson started penning his own story while he was in jail.

"Me and my cellmate would read to each other at night," he told one editor.

"One night I would read out loud to him, the next night he would read out loud to me. And we would do that back and forth until the book was completed," he added. (ANI)
