1845. New York City forms its first police force. The great potato famine hits Ireland. These two seemingly disparate events will change New York City. Forever. Timothy Wilde tends bar near the Exchange, fantasizing about the day he has enough money to win the girl of his dreams. But when his dreams literally incinerate in a fire devastating downtown Manhattan, he finds himself disfigured, unemployed, and homeless. His older brother obtains Timothy a job in the newly minted NYPD, but he is highly skeptical of this new "police force." And he is less than thrilled that his new beat is the notoriously down-and-out Sixth Ward - at the border of Five Points, the world's most notorious slum. One night while making his rounds, Wilde literally runs into a little slip of a girl - a girl not more than ten years old - dashing through the dark in her nightshirt... covered head to toe in blood. Timothy knows he should take the girl to the House of Refuge, yet he can't bring himself to abandon her. Instead, he takes her home, where she spins wild stories, claiming that dozens of bodies are buried in the forest north of 23rd Street. Timothy isn't sure whether to believe her or not, but, as the truth unfolds, the reluctant copper star finds himself engaged in a battle for justice that nearly costs him his brother, his romantic obsession, and his own life.

Six months after the formation of the NYPD, its most reluctant and talented officer, Timothy Wilde, thinks himself well versed in his city’s dark practices—until he learns of the gruesome underworld of lies and corruption ruled by the "blackbirders," who snatch free Northerners of color from their homes, masquerade them as slaves, and sell them South to toil as plantation property. The abolitionist Timothy is horrified by these traders in human flesh. But in 1846, slave catching isn’t just legal—it’s law enforcement. When the beautiful and terrified Lucy Adams staggers into Timothy’s office to report a robbery and is asked what was stolen, her reply is, "My family." Their search for her mixed-race sister and son will plunge Timothy and his feral brother, Valentine, into a world where police are complicit and politics savage, and corpses appear in the most shocking of places. Timothy finds himself caught between power and principles, desperate to protect his only brother and to unravel the puzzle before all he cares for is lost.

The final installment in Lyndsay Faye’s Timothy Wilde series, which Lee Child called “solid-gold” and Gillian Flynn declared “spectacular.” No one in 1840s New York likes fires, copper star Timothy Wilde least of all. After a blaze killed his parents and another left him with a terrible scar, he has avoided flames of all kinds. So when a seamstress turned arsonist threatens Robert Symmes, a corrupt tycoon high in the Tammany Hall ranks, Timothy isn’t thrilled that Symmes consults him. His dismay escalates when his audacious and charismatic older brother, Valentine, himself deeply politically entrenched, decides to run against the incumbent, who they suspect is guilty of assault and far darker crimes. Immediately after his brother’s courageous declaration, Timothy finds himself surrounded by powerful enemies who threaten to harm those he cares about most. Meanwhile, the love of Timothy’s life, Mercy Underhill, unexpectedly appears on his doorstep and takes under her wing a starving Irish orphan who may be the key to stopping the combustions threatening the city—if only they can make sense of her cryptic accounts. The closer they come to deciphering her wild tales of witches and angels, however, the closer Timothy comes to the fiery and shocking conclusion that forces him to face everything he fears most. A boisterous and suspenseful book from a master of historical adventure, The Fatal Flame is a tale for the ages.
