A fierce and respected Parisian cop, Alice wakes up on a Central Park bench with no memory of the night before, handcuffed to a complete stranger—a musician named Gabriel. The night before, she was on the Champs-Élysées, while Gabriel was playing a gig in Dublin. Was she drugged? Kidnapped? And whose blood is on her clothes? Over the next 24 hours, Alice and Gabriel race across New York in search of answers, and in this thriller by France's Guillaume Musso, Alice must finally confront her memories of hunting the serial killer who took everything from her.
