Chicago in 1958 is a very dangerous place. When private eye Lou Fleener and his friend Dion Monkton are tricked into helping a Chicago mob boss in his takeover of Mayor Daley’s office, it makes the other mobs angry enough to kill. Through guns and bombs and the unsteady affections of Cassidy Adams, a blonde with a heart for pure gold, the scary attentions of a hit man who prefers a scalpel to a .38 and a baseball fan who’ll kill them if the Cubs lose, Lou and Monk devise an amazing plan of vengeance against the mobs. All of them. At the same time.
