Jealousy breeds betrayal. A young woman is strangled in her bed. The door is smashed in and the apartment ransacked. Is this a robbery gone wrong? A random attack? A jealous lover? Or a serial killer? It's up to Detective Erin O'Reilly, her K-9 Rolf, and the rest of her Major Crimes squad to find out the truth before anyone else dies. It's a simple case; or is it? Erin has been able to keep an uneasy balance between her personal and work lives. She's always known it was risky to let herself fall for a gangster. But now, she and her boyfriend, smooth-talking Irishman Morton Carlyle, find themselves drawn into a situation in which the only escape is for the two of them to choose a side and take a stand. Jealousy and betrayal are in the air. Who do you trust when your lover could be your enemy?
