This is the fourth installment in the Inspectora Escudero series.

In the city of Cartagena, where the humidity curled the pages of even the oldest books, there lived a man named Luis David Pérez. To the local authorities, he was a nuisance; to the librarians, he was a phantom. But to the underground world of collectors, he was known simply as El Ladrón de Letras —The Thief of Letters.

: The investigation forces Marta to delve into the writer's mind and explore a remote village in the Asturian mountains, where she uncovers dark secrets and deep-seated human sins.
