In the summer of 1979, five Chicago women went missing. The predator, nicknamed The Thief, left no bodies or clues behind--until police received a package from a mysterious woman named Angela Mitchell, whose unorthodox investigations appeared to unmask the killer. Then Angela disappeared without a trace. Forty years later, The Thief is about to be paroled for Angela's murder. But the cryptic file Rory finds in her father's law office suggests there is more to the case.

Making one startling discovery after another, Rory becomes helplessly entangled in the enigma of Angela Mitchell and what happened to her. As she continues to dig, even Rory can't be prepared for the full, terrifying truth that is emerging . . .
