No one is more sympathetic than a mother whose child faces a life-threatening illness. But what if the mother is the cause of the illness? What if the sympathy is the point? Munchausen by proxy (MBP) has fascinated and horrified both professionals and the general public since this disturbing form of child abuse was first identified. But even as the public has been captivated by these tales of abuse and deception, there remains widespread misinformation and confusion about MBP. Are these mothers unfeeling psychopaths, or sick women who need help? And how can we protect the children whose lives are at stake? THE MOTHER NEXT DOOR offers a groundbreaking look at MBP from an unlikely duo: a Seattle novelist whose own family was torn apart by it, and the Texas detective who has worked on more medical child abuse cases than anyone in the nation.
