Clark Carrados: Compradora de Vidas

"Compradoras de Vidas" by Clark Carrados This Spanish-language horror story concerns Norman Shearer, a sociologist in retreat, whose peaceful evening is interrupted when a naked, terrified woman named Rheba Cheadlin arrives at his door fleeing through the rain. A tall, severe man named Robur Crawford appears moments later, claiming Rheba is his patient undergoing nervous treatment at his isolated house, Smoky Hill. Crawford takes her away, but the narrative reveals his true purpose: he and a dying woman named Alitha have been conducting blood transfusions. Crawford extracts nearly four liters from the unconscious Rheba to revive the pallid Alitha, who regains vitality while Rheba expires on the surgical table. Alitha celebrates her three months of renewed normalcy before the cycle must repeat. Shearer, investigating the enigmatic Crawford and the mysterious house amid the sulfurous geothermal features of Smoky Hill, learns from townspeople that Crawford and Alitha maintain a strange cyclical residence pattern—present monthly, then absent for three months. The narrative suggests Crawford systematically procures victims for transfusions sustaining Alitha's vampiric existence.
