GENEALOGY OF A MURDER

The entangled history of the people, incidents, and systems that led to the murder of a police officer in 1960.

On July 7, 1960, a convict out on parole killed David Troy in a holdup gone wrong. Belkin, a former New York Times correspondent and author of Show Me a Hero and Life’s Work, begins her story decades before, tracing the twists and turns of four families to the moment they entwined in that tragic event. From the years before the Great Depression through the following decades of war and economic growth, we come to know not just Troy and his killer, Joseph DeSalvo, but also their ancestors and Dr. Alvin Tarlov, whose support led to DeSalvo’s being granted a second chance. Obsessed with “how any of us become who we are,” Belkin inspects the inflection points that push an individual—and their family tree—into one plot rather than another. As generational stories overlap, the author masterfully builds hand-wringing anticipation of the fateful evening despite having already revealed its shape. Wading into the details of characters’ personal dispositions, successes and failures, and attempts to correct course, she creates a rich backdrop against which to probe the implications of punishment, rehabilitation, and recidivism in America’s system of imprisonment and parole. She deftly manages the particularities of a wide catalog of individuals and their historical and cultural contexts, teasing out pertinent insights into how America treats its prisoners; the tenuous position of parolees and the system surrounding them; and the messy connections among fate, dispositions, and outcomes. If never decidedly answering some of her questions about the case, Belkin creates an impressive work of in-depth narrative journalism that artfully conveys the countless paths a life can follow and exposes the instinctual human desire for alternative endings.

An absorbing, thought-provoking inquiry into what it means to change and defy the odds.
