Xibalba

A group of researchers who lived isolated inside deep Yucatan caves, trying to simulate life conditions of a mission to Mars, have suddenly severed all communications: there's no more trace of life from the group's members. While in Mexico City for a congress, the Detective of the Impossible stumbles upon the researchers' tracks and is forced to clash with a blood-thirsty gang of drug dealers. He will have to face an enigma whose roots are set in the depths of time and space. If he wants to solve the puzzle, Martin will have to cross the dark doorways of Xibalba, the afterworld ruled by the Mayan spirits of disease and death!
