The Godfather's revenge

It is 1963 in New York, and things have never been better for the Corleones. They've taken out their Mafia rivals, and legitimised the Family. Michael Corleone and Tom Hagen - Vito Corleone's adopted son, and the glue that holds the family together - are closer than they've ever been. Outside the fortified building owned by Michael, newly undisputed Boss of Bosses, a parade of people wait to ask the great man for favours. Among the visitors are former mob rivals, an emissary from the Mayor of New York, even faces from the past like Jonny Fontane; all come to pay homage. The Mafia Don walks the streets of his New York, beloved and protected.
But one problem remains. Michael has sworn revenge upon the traitorous former Corleone capo, Nick Geraci. Up until now Geraci, who has powerful friends and far too much to say, has evaded him. And that night, as the fireworks begin to explode over First Avenue, comes the news that Jimmy Shea, President of the United States, has been assassinated. Was another mob family involved? Or did the Corleones have a hand in the killing of their old friend?
