Skull Face by Robert E. Howard

A grim pulp-horror/espionage tale in which a scarred, skull-masked mastermind engineers a worldwide conspiracy to wreck Western civilization using a blend of occult knowledge and modern subversion; pursued by a hard-bitten, war-scarred narrator, the plot unfolds through betrayals, exotic investigations, and violent confrontations as the protagonist unravels the villain’s vengeful motives and seeks to stop an impending catastrophe.
