United States and the Empire of Japan, a popular subject at the time. Japan does not declare war but instead launches sneak attacks on United States ships en route to the Philippines and Hawaii; an invasion fleet about to launch a surprise attack on San Francisco is stopped by the hero using the weapon from a captured Japanese vessel. The title refers to an ultraviolet searchlight used by the Japanese, but invented by the Americans, to blind American crews. Robertson authored Primordial / Three Laws and the Golden Rule, a novella about shipwrecked children growing up together and falling in love on a desert island. Fans of Edgar Rice Burroughs acknowledge Robertson's contribution to the works of Henry De Vere Stacpoole, particularly The Blue Lagoon. They believe that both Robertson's and Stacpoole's writings influenced Burroughs in his creation of Tarzan of the Apes. Death On the afternoon of March 24, 1915, Robertson was found dead in his room at the Alamac Hotel in Atlantic City, New Jersey. He was 53. It was believed that he died of an overdose of paraldehyde.
