Алекс by Pierre Lemaitre

When a young woman is violently abducted from her ordinary life, a brilliant but troubled detective throws himself into a relentless manhunt that peels back layers of cruelty, obsession and secrecy; as the investigation exposes unexpected connections and moral compromises, it becomes a tense, emotionally charged race to confront a remorseless perpetrator and to reckon with the costs of justice and revenge.
