Former English professor Roberta Cambridge's corpse is found in one of the NYC cars destined to bring mayor Robert Weldon's party to a literary event but it's reported stolen and she was murdered hours earlier. Even her sister ignores why she left, six months earlier, her fine career and apartment to become a phone sex worker. She probably stumbled upon a dark secret there. Castle's friendship with the mayor may compromise his position on the team when the investigation leads to presumed transfers of charity - to electoral funds and the mayor, who hoped to run for governor, refuses further cooperation.
