Policing a wild town like Chicago takes strong nerves and a steady hand. Billy Doran has been doing it for 20 years. Now he is joined by a partner he never wanted, rookie Arthur Diamond. Together they meet the challenge of reining in the wicked and unruly in a partnership forged out of necessity and refined in fire. Here for the first time in one volume are their first three explosive cases, Madman, Poison & Vendetta.
