I agree. I think Murder Machine is one of the best books about the mafia ever. And a great read for anyone interested in true crime or serial killers.

Gaspipe is good as a companion piece to other books. If you are looking for a history of Casso's mafia career, you can get most of it from the good rat by jimmy breslin, five families by selwyn raab or the new book on al d'arco by capeci - all great books. If you are looking for every little fact about Casso, then go ahead and read Gaspipe.

But many people have said the book is biased and bends the truth. It's written by a close family friend of his who lived next door to him. I think Casso may have personally edited it.
