In his previous best-seller, Natural Causes, Dr. Michael Palmer drew on decades of emergency-room experience to create a terrifyingly realistic world where the line between medicine and murder is scalpel-thin. In Silent Treatment, he crosses this line with a heart-pounding thriller guaranteed to satisfy fans of medical suspense. When his wife mysteriously dies the night before she is scheduled for surgery, Dr. Harry Corbett realizes a killer is moving through the wards of Good Samaritan Hospital-a killer so sophisticated and silent that he can only be a doctor.
