Yes, Joe, I did read "A Man of Honor." Look back at my post: it was the first source I quoted. I acknowledged that Bonanno said Magaddino kidnapped him. Others thought differently.
My conclusion was (sorry to quote myself): "You decide." With Bonanno dead, no one will ever know for certain what happened with that disappearance. But, as I said, there was ample reason for Bonanno to have arranged his own disappearance.
