No one in 1840s New York likes fires, but Copper Star Timothy Wilde least of all. So when an arsonist with an agenda begins threatening Alderman Robert Symmes, a corrupt and powerful leader high in the Tammany Hall ranks, Wilde isn’t thrilled to be involved. His reservations escalate further when his brother Valentine announces that he’ll be running against Symmes in the upcoming election, making both himself and Timothy a host of powerful enemies.
Meanwhile, the love of Wilde’s life, Mercy Underhill, unexpectedly shows up on his doorstep and takes under her wing a starving orphan with a tenuous grasp on reality. It soon becomes clear that this wisp of a girl may be the key to stopping those who have been setting fire to buildings across the city—if only they can understand her cryptic descriptions and find out what she knows. Boisterous and suspenseful, The Fatal Flame is filled with beloved Gotham personalities as well as several new stars, culminating in a fiery and shocking conclusion.
