From a New York Times–bestselling author—a chilling crime thriller set in colonial America about a mass murderer's bargain with his captors.

In 1702, Matthew Corbett is an apprentice problem solver for the Herrald Agency, currently tasked with accompanying serial killer Tyranthus Slaughter on a journey from a Philadelphia asylum to the New York City waterfront. But during the trip, Mr. Slaughter tempts Matthew and his colleague Hudson Greathouse with an unexpected offer—leading to catastrophic outcomes.

This darkly compelling novel delves into both the mind of a murderer and the process of a city and a nation moving into the future.
