With political tensions running high due to a controversial new motorway scheme, the chilling and ritualistic murder of a high-flying local government minister sends shockwaves through the island. When her home is ransacked and another brutal killing occurs, Isabel Flores Montserrat, unorthodox former detective, joins up once again with Mallorca's police chief, Tolo Cabot, in a perilous race for answers. Meanwhile, fear and distrust grow in Isabel's village as fake signs and cairn markers send disorientated hikers plunging off cliffs. Is this mountain mischief the work of environmentalists or is something far more sinister afoot?
