"Martín León Mercado, historiador frustrado y anacoreta urbano, cegado por el relumbrón del exotismo y anestesiado por el beinestar material, acepta ser parte de un estudio sobre un brote de fobias contagiosas por la zona litoral de Guayanilla y Tallaboa. Rodeado de eventos altamente sospechosos y subordinado a instrucciones incomprensibles de parte de un jefe críptico e inaccesible, se somete al encierro cada vez mayor del Castillo, que poco a poco intenta engullirlo a pesar de múltiples intentos por liberarse de su pasado, de su desidia y de sus fobias"-- Martín León Mercado, frustrated historian and urban anchorite, blinded by the glitter of exoticism and anesthetized by the material beinestar, agrees to be part of a study on an outbreak of contagious phobias in the coastal zone of Guayanilla and Tallaboa. Surrounded by highly suspicious events and subordinate to incomprehensible instructions from a cryptic and inaccessible chief, he is subjected to the castle's increasing confinement, which gradually attempts to engulf him despite multiple attempts to free himself from his past, his laziness, and his phobias.
