On Christmas Eve, a desperate young woman arrives with an impossible request: find her vanished father before her grandmother dies. For a detective who has spent months avoiding real cases, it should be easy to say no. But once he steps into the world of the Aldens—a powerful family polished by money, silence, and old secrets—he finds himself trapped in a web of disappearance, inheritance, and carefully managed lies. Moody, elegant, and razor-sharp, The Arrangement is a literary mystery where every closed door hides another bargain, and the truth is the one thing no one can afford.
