Coming in September there will be a documentary airing on Netflix about the life and crimes of Tomasso Buscetta. The creators managed to track down Buscetta's wife and last living son in Florida and ultimately convinced them to partake in their film. One of the best mafia books I ever read was The Last Days of The Sicilians and it gave a really in depth look into who he was and his relationship with Gaetano Badalamenti who was more than likely responsible for the death/disappearance of atleast one of Buscetta's sons in Sicily. He was one of the more interesting Sicilian cooperators imo.
