Book excerpt: A tale of crime and punishment from a prizewinning writer. A few years ago, Andy Rosenzweig, an inspector for the Manhattan District Attorney's office, was abruptly reminded of an old, unsolved double homicide. It bothered him that Frankie Koehler, the notoriously dangerous suspect, had eluded capture and was still at large. Rosenzweig had known the victims of the crime, for they were childhood friends from the South Bronx: Richie Glennon, a Runyonesque ex-prizefighter at home with both cops and criminals, and Pete McGinn, a spirited restaurateur and father of four. Rosenzweig resolved to find the killer and close the case. In a surprising, intensely dramatic narrative, Philip Gourevitch brings together the story of Rosenzweig's pursuit with a mesmerizing account of Koehler's criminal personality and years on the lam. A Cold Case carries us deep into the lives and minds, the passions and perplexities, of an extraordinary cop and an extraordinary criminal whose lives were entwined over three decades. Set in a New York City that has all but disappeared, and written with a keen ear for the vibrant idiom of the colorful men and women who peopled its streets, this is nonetheless a book for our times. Gourevitch masterfully transforms a criminal investigation into a searching literary reckoning with the forces that drive one man to murder and another to hunt murderers."
