(This is the second edition of this book through a different publisher.) Joyce Lattimer is thrilled to work in a Boston hospital's Neonatal Intensive care Unit, but while caring for the helpless infants she discovers that someone is murdering them there. She and her friend, Nancy, uncover evidence to show that Martha Ryan is responsible for the deaths of at least 20 infants. The hospital administrators refuse to believe that one of their own would do such a horrible thing and their solution is to "upgrade" the NICU to all RN's which removes Martha, who is an LPN, from the unit. Martha is moved to the pediatric unit where she continues to create problems.Joyce wants Martha's license revoked and continues to work to that end only to find that a mysterious caller begins to threaten her family and friends. Trying to protect those she loves and the children at the hospital becomes her obsession and her downfall.
