In Silk Suit/Stone Heart, two high-profile murders are investigated by Homicide Detectives Cat Leigh and Marci Welles. First, they must track a killer who is murdering politicians during dinner in local restaurants. The fact that he or she is using a radioactive chemical element more commonly found in Russia than the U.S.A. gives the crimes an aura of international intrigue and espionage.
Cat and Marci are also tasked with investigating the murder of one of Palm Beach County's most well-known organized crime leaders. Sixty-year-old Vincent Colangelo was ruthless. While still in his forties, he gained control of the most powerful families on the east coast and rules with an iron fist. When his body was found in the penthouse suite of the Ritz Carlton Manalapan, the list of suspects included his most trusted confidant his wife.
