(One Wrong Step). When the journalist Xavier Huguet decided to walk the Camino de Santiago to send a daily chronicle to his newspaper, he never imagined he would become the clue to solving the brutal murder of a university professor whose body turned up decapitated. And nothing could predict that the death would be connected with the mysterious anonymous messages against the Jubilee Year appearing on the door of the Cathedral of Santiago. Perhaps the most exciting thriller written to the backdrop of the Camino de Santiago.
