It is 1908, and international tensions are mounting as the world plunges toward war. When a brilliant American battleship gun designer dies in a sensational apparent suicide, the man's grief-stricken daughter turns to the legendary Van Dorn Detective Agency to clear her father's name. Van Dorn puts his chief investigator on the case, and Isaac Bell soon realizes that the clues point not to suicide but to murder.

A no-nonsense detective is on the trail of the sharpest and deadliest criminal mind he has ever encountered: a serial robber who murders any and all witnesses in cold-blood.

Billy Harney was born to be a cop. The son of Chicago's chief of detectives, whose twin sister is also on the force, Billy plays it by the book. Alongside Detective Kate Fenton, Billy's tempestuous, adrenaline-junkie partner, there's nothing he wouldn't sacrifice for his job. Enter Amy Lentini, a hard-charging assistant state's attorney hell-bent on making a name for herself - who suspects Billy isn't the cop he claims to be. They're about to be linked by more than their careers.
