After a 4AM crash at her banking job, Elena Chen wakes up not in New York—but as a consulting detective in an 18th-century city where murder comes before breakfast. With a dangerously perfect assistant, Adrian, and a mysterious outsider, Lucien, watching her every move, Elena must solve deadly cases to survive a world that feels more like a game than reality. But the deeper she digs, the more she realizes the real mystery isn’t who’s dead—it’s why she’s here.
