Clemenza - The Godfather Returns

Clemenza's gradual takeover of the Corleone empire in New York is briefly covered in The Godfather Returns, Mark Winegardner's sequel to Puzo's original novel. It also tells of Clemenza's involvement during Michael's return from exile and eventual, official initiation into the Corleone crime family. Most noteworthy, the novel depicts Clemenza's fatal heart attack (mentioned in The Godfather Part II), and the many conspiracy theories that he had actually been murdered by the Rosato Brothers, enemies of the Corleone Family.
