When Harvard professor and forensic scientist Will Hewitt autopsies the victims, he discovers that Munro was murdered. Dr. Hewitt needs help navigating the city and its complex society to find the killer. He turns to governess Nell Sweeney, who understands the world of the rich and how their power can be used to hide their secrets. The investigation leads to the conclusion that these men were concerned more with keeping some things hidden than with the loss of their money.
