Private Vegas by James Patterson

Private investigator Jack Morgan is on the hunt for a murderer in Las Vegas—and the murder ring he uncovers is unlike anything he's ever seen. Las Vegas is a city of contradictions: seedy and glamorous, secretive and wild, Vegas attracts people of all kinds—especially those with a secret to hide, or a life to leave behind. It's the perfect location for Lester Olsen's lucrative business. He gets to treat gorgeous, young women to five-star restaurants, splashy shows, and limo rides—and then he teaches them how to kill. Private Jack Morgan spends most of his time in Los Angeles, where his top investigation firm has its headquarters. But a hunt for two criminals leads him to the city of sin—and to a murder ring that is more seductively threatening than anything he's witnessed before. Chilling and marvelous, Private Vegas brings James Patterson's Private series to a sensational new level.
