It is also a portrait of a woman’s obsession and her unflagging pursuit of the truth. Framed by an introduction by Gillian Flynn and an afterword by her husband, Patton Oswalt, the book was completed by Michelle’s lead researcher and a close colleague.Utterly original and compelling, it is destined to become a true crime classic - and may at last unmask the Golden State Killer.
