If you're not satisfied with any non-fiction that you find on Schultz, you could try E.L. Doctorow's novel, "Billy Bathgate," which contains many factual threads. This was an ok (not great) movie, too--enlivened by a superb performance by Dustin Hoffman as Schultz.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
