The tables have turned. The Informant is dead; the Collector is on the run. Valkyrie knows the serial killer's real name now. She's about to learn his past. The only thing coming between Val and her long-sought revenge is the final missing piece of the puzzle: Why her? What connects the killer to her family? If Val can unravel the plot in time, she might find the answers to all her questions and save dozens of lives. But if her plan succeeds, and she finally meets the Collector face to face, one chilling fact remains, which the killer reminds her in his own words: "Somebody's gotta die."
