Mo-Sanshon!

"Mo-Sanshon!" by Bryce Walton is a science fiction novella that was published in the summer of 1947. The narrative unfolds in a futuristic world where humanity grapples with the existence of a mysterious alien species known as the Mo-Sanshon, an ant-like civilization that may infiltrate and threaten humanoid societies. The story touches on themes of paranoia, identity, and the struggle for survival against an unseen menace. The plot centers around Professor Jonathan Ward, a beleaguered entomologist who believes that the Mo-Sanshon have penetrated human culture, causing chaos and disorder behind a facade of normalcy. After being labeled a “psycho” by the world psychometric council for his alarming beliefs, Ward desperately fights to escape his confinement and prove the reality of the alien threat. He is aided by a mysterious taxi driver named Red, who reveals himself to be a rebel against the Mo-Sanshon. Together, they concoct a daring plan to return to Mars with evidence to combat the alien threat by unleashing a specially bred army of mercenary insects. As they contend with the Mo-Sanshon's telepathic influence and formidable power, the precarious balance between sanity and insanity unfolds, ultimately leading to a gripping climax that challenges the essence of humanity and survival.
