Not an organized crime book per se, but it delves into the Jewish (Zwillman and his Minuteman) fight against the Newalr/Irvington Nazi's. Its a interesting book to say the least. The book is "Nazi's in Newark" and I bought it for 25 bucks on line. Zwillman did not commit suicide, no way, no how. The police may say he did but he didn't. In fact, in my opinion his murder is as fascinating as JFKs.
