On a sweltering day in Florence, art student and newlywed Mary Warren wandered into a shady tunnel of trees. Within minutes, she was brutally attacked and her husband murdered. And within months the killer was identified, caught, and dead. It'¬"s now two years later, and Mary has returned to Florence at the invitation of her lover '¬ ; a relationship that predates what she insists on calling the '¬Saccident.'¬ Crumbling and beautiful, Florence is eternally compelling. But more and more, what Mary sees is not the glories of the city, but its dark underside '¬ ; specifically, one dead young woman after another. She also can'¬"t help seeing a terrifying pattern: Either this is a copycat killer, or her husband'¬"s murderer is still on the loose.
