The story centers around Philip Merriwether, an ordinary man with a remarkably poor memory who unwittingly becomes the most knowledgeable person on Earth due to a bizarre incident involving a top-secret scientific experiment. The novella explores themes of intelligence, espionage, and the unforeseen consequences of technology. In the narrative, Dr. H. Wolstadt conducts an experiment on a communication beam that inadvertently transfers vast amounts of knowledge into Merriwether's mind when he faintly crosses its path. After this unusual event, Merriwether steps into a new identity, showcasing incredible intelligence and knowledge about highly classified information, which ultimately leads to an FBI investigation that labels him an espionage suspect. As authorities scramble to understand how Merriwether obtained this critical intel, the story culminates with him realizing that he can use his newfound abilities to further accrue secrets, setting the stage for a blend of comedy and intrigue in a world where mere incompetence can transform into unparalleled genius.
