"I need you darling, come and go with me." Song lyrics

Lisa Scottoline provides a view of the depth of a mother and step-mother's love and the extent that a mother might go to in order to protect her family.
Jill's former stepdaughter, Abby appears at Jill's home in a distraught manner and announces that her father, Jill's former husband, William, has been murdered.
Jill is a pediatrician and learns that William died four days ago from a heart attack brought on by mixing perscription drugs and alcohol. Abby thinks he was murdered and since Jill is a doctor, she could check into William's death.
Jill is moved by Abby's sadness. When she and Megan, Jill's and William's daughter attempt to attend a memorial for William, his other daughter, Victoria, demands that she leave and accuses Jill of abandoning them.
Megan is a young teenager and asks her mother for an explination. Jill explains that when Jill and William were wed, he stole from her, even took perscription pads which could have ruined her as a doctor.
Reluctantly, Jill does investigate the facts surrounding William's death and comes to certain conclusions while Abby acts like a pampered, selfish, dislikable brat. Jill excuses her behavior and overlooks everything in her love for her.
Things are going in what seems to be a predictable manner when Lisa Scottoline demonstrates her story telling skills with a wonderful change of direction. The concluding part of the novel will make the reader sit up in their seat and cheer.
