THE writer should know his subject well because, in 1996, he produced an award-winning, long profile for Esquire magazine with which Sinatra cooperated fully. It gives a sense of the man behind the kaleidoscope of images through which he projected himself: crooner, actor, tough guy, comic, ladies' man, man's man, hellraiser. Zehme made it his business to collect the myriad stories that bore witness to these various personae. The article was notable because it was the first time Sinatra was revealed in all his flawed humanity: generous, jealous, loyal, tempestuous. He was a lot more than a pretend mobster.
