But when he arrives, he's disturbed to find blood on Marla's front door. He's even more disturbed to find Marla nursing a baby, that she claims was delivered to her 'by an angel'. Soon afterwards, a woman's body is discovered, stabbed to death, her own baby missing. It looks as if Marla has done something truly terrible. The evidence seems overwhelming, but David just can't believe that his cousin is a murderer. Then who did kill Rosemary Gaynor? Why did they then take her baby and give it to Marla? It's up to David to find out what really happened, but he soon discovers that the truth could be worse than he ever imagined ...
