Two cops hunt a serial killer, and a young blind woman fights to stay alive Crossing Flatbush Avenue is never easy, and for Lorraine Cho, it's the most dangerous part of her day. Her job as a medical report transcriber is on the other side of Flatbush--and Lorraine was blinded in an accident several years ago. She is waiting to cross one evening when a stranger offers to help. Just before they reach the safety of the sidewalk, Lorraine's benefactor shoves her into the back of a van and speeds away.   Across town at police headquarters, Roland Means toils in purgatory. A street cop with a violent streak, he's on ice in the ballistics lab, waiting while the New York Police Department tries to decide whether he's a psychopath or a thug. Lucky for him, a serial killer has been terrorizing New York, and Captain Vanessa Bouton needs a tough detective. Bouton wants evidence to prove a cover-up theory, and Means is willing to be cannon fodder just to get back on the street. Though neither of them knows it, Lorraine Cho's life is in their hands.
