A year after the devastating events that took place in Fool Me Once, Harlan Coben's bestselling thriller and #1 Netflix series, a secret from former Detective Sami Kierce's college days comes back to haunt him. Present day is hard enough for the disgraced Kierce, but his past isn't through with him yet...

Sami Kierce, a young college grad backpacking in Spain with friends, wakes up one morning, covered in blood. There's a knife in his hand. Beside him, the body of his girlfriend. Anna. Dead. He doesn't know what happened. His screams drown out his thoughts--and then he runs.

Twenty-two years later, Kierce, now a private investigator, is a new father who's working off his debts by doing low level surveillance jobs and teaching wannabe sleuths at a night school in New York City. One evening, he recognizes a familiar face at the back of the classroom. Anna. It's unmistakably her. As soon as Kierce makes eye contact with her, she bolts. For Kierce there is no choice. He knows he must find this woman and solve the impossible mystery that has haunted his every waking moment since that terrible day.

His investigation will bring him face-to-face with his past--and prove, after all this time, he's nobody's fool.
