Devil's Waltz

The doctors call it Munchausen by proxy, the  terrifying disease that causes parents to induce  illness in their own children. Now, in his most  frightening case, Dr. Alex Delaware may have to prove  that a child's own mother or father is making her  sick.

Twenty-one-month-old Cassie Jones  is bright, energetic, the picture of health. Yet  her parents rush her to the emergency room night  after night with medical symptoms no doctor can  explain. Cassie's parents seem sympathetic and  deeply concerned. Her favorite nurse is a model of  devotion. Yet when child psychologist Alex  Delaware is called in to investigate, instinct tells him  that one of them may be a monster.

Then  a physician at the hospital is brutally murdered.  A shadowy death is revealed. And Alex and his  friend LAPD detective Milo Sturgis have only hours  to uncover the link between these shocking events  and the fate of an innocent child.
