#1 New York Times bestselling author Kathy Reichs returns with a twisty, surprise-packed thriller featuring forensic anthropologist Temperance Brennan, who finds herself at the center of an arson investigation, a deepening mystery, and a stunning culmination of violence and deception.

It’s never easy working fire scenes, Tempe thinks. Called to Washington, DC to analyze the victims of a building set ablaze amid mysterious circumstances, she sees all of her misgivings justified. The building site is in Foggy Bottom, a neighborhood with a colorful past and present, and the residence’s ownership becomes even more suspicious when Tempe delves into the building's past.

The pieces start falling into place strangely and quickly, and, sensing a good story, Tempe teams with a new ally, telejournalist Ivy Doyle. Soon the duo learns that back in the thirties and forties the property belonged to a member a group of bootleggers and racketeers known as the Foggy Bottom Gang. Though interesting, this fact seems irrelevant—until the son of a Foggy Bottom gang member is shot dead at his farm in Fairfax County, Virginia. Coincidence? Targeted attacks? So many questions.

As Tempe and Ivy dig deeper, an arrest is finally made. Then another Foggy Bottom Gang-linked property burns to the ground, claiming one more victim. Slowly, Tempe’s instincts begin raising flags. Have too many of her moves while in Washington been anticipated in advance?

Long after that first fire is extinguished its flames of consequence spread outward, and eventually Tempe finds herself fighting for her life.
