Fresh-faced homicide detective Tracy Sterling has been thrown into the deep end. She's navigating the city's darkest corners to unmask a killer whose methods are as chilling as they are cryptic. A grotesque spectacle was discovered in an alley by a nightclub. Another chilling scene lay within the shadows of an alley next to a public library. Who could commit such monstrous acts? And what is the sinister pattern hiding within their horrific handiwork? Tracy must grapple with a shocking lack of evidence, while potential witnesses seem to shroud the truth in fear and lies. And all the while, the nameless killer observes the investigation from the shadows, delighting in the terror he sows. The case seems unsolvable. But failure is not an option. For if she cannot solve the puzzle, the dance of death will continue unabated, and the killer will strike again and again. But Tracy isn't just determined, she's obsessive. And she won't stop until she's put every puzzle piece in place, exposing the killer, along with other shocking surprises that will shake the city to its core.
