Doc Savage: El Aniquilador

"El Aniquilador" by Kenneth Robeson, the 23rd Doc Savage adventure (Spanish-language pulp). A mysterious killer strikes New York: victims die with grotesquely bulging eyes, their bodies showing no violence. After seven deaths across Manhattan and the Bronx, the pattern becomes public panic—an apparent epidemic. At a health association office, a small, dark-haired man murders a portly official with gunshots, then dies on the stairwell exhibiting the same horrifying eye dislocation. Police discover an identification bracelet on the corpse referencing "Doc Savage," summoning the bronze-skinned adventurer. Doc—described as an extraordinarily powerful, golden-eyed man of scientific genius—arrives in his reinforced roadster, contacting his team via radio. The narrative establishes a serial murder mystery entangling Doc and his specialized companions in uncovering the killer's method.
