They spoke a bit on Giancana's rise in the book, The Outfit by Gus Russo. I find it very interesting how Giancana was basically given his start in the big money rackets, by a black gangster like Eddie Jones. It seems that at one point early on Giancana was extremely close to Jones and his group of ethnic racketeer's, much more so than he was early on with Outfit guys.
That was just his( Giancana's) way to weasel his way into Eddie rackets in order to usurp it from him. I doubt there was any true genuine friendship on Giancanas part.
