Inspector Rafael sought nothing more than a few days of peace and tranquility at a luxurious, secluded spa in the northern peninsula. However, when an unrelenting blizzard completely isolates the resord, his anticipated rest vanishes into the freezing air: the lifeless body of a colonel is discovered under deeply suspicious circumstances.
What initially appeared to be a tragic, isolated accident soon reveals itself as the first link in a macabre chain of deaths that shatters the calm of the sanctuary. Unable to call for reinforcements and surrounded by guests harboring dark secrets—from the enigmatic and seductive Ángela to the reserved Father Tomás—Rafael is forced to cobble together an impromptu investigative team to stop a calculating killer lurking among them.
Trapped by the unforgiving winter and a pervasive atmosphere of mistrust, the inspector and his makeshift team face a labyrinth of moral dilemmas, hidden loyalties, and long-buried vengeances. Can the inspector unmask the murderer before they strike again, or before he becomes the next victim?
Murder at the Spa intertwines the suspense of the finest classic mysteries with the unspeakable secrets of a retreat that, far from curing ailments, has become the stage for a lethal game of chess.
