Doherty, a former New York prosecutor is now in a dead-end legal job with the city's Department of Education. His life suddenly changes when a school principal asks him to look into the 30-year-old murder of her twin sister. The murder was one of a series of unsolved killings of young women in New York dubbed the Ides of June Murders by the media. Along with his close friend Hank Lowrie Jackson, a Native American working for an unnamed Executive Branch agency, Doherty delves into the killing, only to find out someone is desperate to derail his investigation. Pursuing the matter, Doherty manages to raise the suspicions of the FBI, incur the wrath of a mobster, and match wits with a hired assassin, all the while tending to his three cats and convincing Dana, his long time love, not to take a job in Boston. Doherty realizes his investigation must go on; the only way Dana and he can stay alive is to solve the murder and expose those responsible.
