9. Come and Kill Me

July 4, 1930.  40,000 horse racing fans fill Arlington Park.  Ness and his men have Arnold ""Spats"" Vincent under surveillance; they will close in on him as soon as he gets a piece of paper: a list with the names of officials in high places who are ready to do business with the crime cartel.  2 hoods (one tall, one short), apparently associates of Spats, approach him.  The tall hood sits next to him and whispers something to him; then he stabs Spats.
