There's an American Mafia article about the Last Testament Of Lucky Luciano and its authenticity. While it was a movie script originally, it only became a book after Luciano got word from NY that he wasn't allowed to make no movie. The people who doubted the book and if it even came from Luciano himself, have also written a shitload of inaccuracies in their own Luciano books. Neither of those containing Luciano's own words. I don't think it can be doubted that the Last Testament book is really Luciano's own testimony, however the common belief is he himself wasn't truthful with the author. It should be noted that all those who criticized the Last Testament book, in their own books write about the Night Of The Vespucci, as if it actually happened. It's now common fact that Luciano didnt have a bunch of mustache petes in 15 states murdered all within a few hours. The Last Testament was the only book at the time that denied it happening in the first place.

It's possible Luciano was directly involved with Marazano's murder. But I personally doubt it and think the Murder Inc. Jew squad theory, is a lot closer to reality than people think.
