Harvey's tough talking, Aeschylus quoting, former Irish cop turned PI, Michael Kelly, is back in another sizzling murder mystery that pits him against a merciless sniper on the loose in Chicago's public transportation system. After witnessing a shooting on an L platform-and receiving a phone call from the killer himself-Kelly is drawn toward a murderer with an unnerving link to his own past, to a crime he witnessed as a child, and to the consequences it had on his relationship with his father, a subject Kelly would prefer to leave unexamined. But when his girlfriend-the gorgeous Chicago judge Rachel Swenson-is abducted, Kelly has no choice but to find the killer by excavating his own stormy past.
