In Silk Suit/Stone Heart, two high profile murders are investigated by Homicide Detectives Cat Leigh and Marcia Welles. Under pressure from higher ups in the Palm Beach County Sheriff's office, the partners must uncover who is murdering politicians using a nearly untraceable radioactive chemical element more commonly found in Russia than the USA. Cat and Marci must also solve the murder of Vincent Colangelo, Palm Beach County's well-known, handsome, debonair law breaker. Vincent was ruthless. While still in his forties, he gained control of the most powerful organized crime family on the east coast and ruled with an iron fist. When his body is found in the penthouse suite of the Ritz Carlton Manalapan, everyone is a suspect… even his most trusted confidant.
