Always apprehensive about working fire scenes, Tempe is called to Washington, DC, to analyze the victims of a deadly blaze and sees her misgivings justified. The devastated building is in Foggy Bottom, a neighborhood with a colorful past and present, and Tempe becomes suspicious about the property's ownership when she delves into its history. 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 home was the hangout of 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 home in an affluent part of the district. 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 pointing to the obvious: somehow, her moves since coming to Washington have been anticipated, and every path forward seems to bring with it a lethal threat.
