NYC's number one detective, Michael Bennett, has a huge problem – someone is recreating the crimes of infamous killers from New York's history. The city has never been more terrified.
A rash of horrifying crimes tears through the city, throwing it into complete chaos and terrorising everyone living there. Immediately, it becomes clear that they are not the work of an amateur, but of a calculating, efficient, and deadly mastermind.
The city calls on Detective Michael Bennett, pulling him away from a seaside retreat with his ten adopted children, his grandfather, and their beloved nanny, Mary Catherine. Not only does it tear apart their first vacation since Michael's wife Maeve died – it leaves the entire family open to attack.
Bennett enlists the help of a former colleague, FBI Agent Emily Parker. As his affection for Emily grows into something stronger, his relationship with Mary Catherine takes an unexpected turn. All too soon, another appalling crime leads Bennett to a shocking discovery that exposes the killer's pattern and the earth-shattering enormity of his plan.
