Harley Quinn follows the evidence-and it leads her to a dangerous conclusion: she might know the true identity of the serial killer she's hunting. But as Harley digs deeper into The Joker's past, he is watching heràand leaving a trail of bodies in his wake. Gotham City has never needed a hero more!
