White Sister

Leaving L.A.'s Parker Center, Shane Scully and his wife, Alexa, agreed to meet at home in one hour. Shane gets there; Alexa doesn't.
This tale turns deadly, when in the middle of the night, he's called to a crime scene on Mulholland Drive, where the victim, who appears to be a gang member has been handcuffed and executed, gangland style. What's worse is that the victim's body is in Alexa's car. Her service revolver, which Shane discovers nearby, is probably the murder weapon. But Alexa is missing.
