A woman is shot as she waits for her train to work. An hour later, a second woman is killed as she rides an elevated train through the Loop. Then, a church becomes the target of a chemical weapons attack. The city of Chicago is under siege, and Michael Kelly, former cop turned private investigator, happens to be on the scene when all hell breaks loose. Kelly´s brassy investigating and razor-sharp instincts lead him into an intricate plot involving a retired cop, a shady train company, and a quietly ticking weapon nestled deep in the city´s underbelly. But when his girlfriend - the gorgeous judge Rachel Swenson - is abducted, Kelly realizes that the only way he´s going to find the killer is to excavate his own stormy past.
