In a world where a joke can pass for gospel and truth is treated like a rare chemical, a skeptical narrator remembers his formidable Grandma, a tiny farm matriarch with an iron will and a mysterious "lie soap" that could cure a child of falsehood forever. Her comic, ruthless discipline, once tested on a boastful city cousin, becomes the seed of a much larger obsession when the narrator grows up amid chemistry labs, corporate research, political disappointment, and a broken engagement that leaves him disillusioned with a culture built on spin. Returning to Grandma's farm, he seeks the recipe as a way to change the world, only to discover that the soap does more than stop lies: it destroys self-deception itself. With the help of an advertising man, the miracle becomes a wildly successful toothpaste and mouthwash, and soon truth spreads through society like fire. Churches, lawyers, politicians, criminals, and even global powers are forced into startling honesty, toppling institutions and reshaping the world. But as peace and candor grow, so does a new danger: a population too gullible to imagine deceit. In the end, the narrator faces the mirror and the hardest question of all: "Did I do right?"
