El último verdugo (Trilogía del verdugo 1) (Spanish Edition)

A series of brutal murders confounds police investigators. The victims bear a strange mark on the back of their necks, and each body is accompanied by a cryptic note reading "Alguien tiene que hacerlo" (Someone has to do it). A serial killer is executing victims using a garrote vil—the same instrument employed by executioners centuries ago and considered one of the cruelest killing devices ever created. Why does the killer employ such a macabre method? What connects the victims? Why does he leave bodies in specific Barcelona locations, as if the city itself is part of his message? When Dr. Lena Mayoral, a renowned forensic psychologist with a troubled past, is tasked with investigating the killer's mind, the case becomes increasingly complicated and dangerous. As the body count rises and media pressure mounts, Lena becomes obsessed with a killer who appears to be playing a deadly game directly with her. This is the first book in the Trilogía del verdugo series.
