“Written with Caputo’s customary style and razor-sharp prose, Equation for Evil is the rarest of novels: one that makes the reader think profoundly at the same time that he is driven to devour pages. Unflinching, compelling and engaging, it stands beside books like Presumed Innocent or The Silence of the Lambs and is equally fascinating.” -- John Banville From Pulitzer Prize-winning journalist and National Book Award finalist Philip Caputo, a timely thriller that is sure to have you on the edge of your seat On a quiet morning in California, a lone gunman opens fire on a busload of children headed for a field trip, then turns the gun on himself. Forensic psychiatrist Leander Heartwood and special agent Gabriel Chin team up to investigate the case, seeking at first only to solve this single disturbing crime but in time delving into issues of race, morality, and the complex forces at work in all horrifying acts of violence. Part mystery, part psychological thriller, part piercing social commentary, Equation for Evil is a riveting and incisive meditation on violence and the nature of evil.
