A Contribution to the History of Happiness reads like a detective story. The police find the body of a businessman hanged in his home, accused by the police without evidence of having groped some women. An honest policeman who questions the story of his suicide leads him to a house inhabited by women who have decided to implement justice in their own way, tracking down the men who desecrated women's bodies and punishing them mercilessly, not because the genre is popular, but because rape is a crime.
The policeman has an affair with the businessman's wife, in order for the author to prove that rape has nothing to do with sex, a thorny topic that makes the reader, after reading the novel, grateful to the author for presenting a thorny issue and following it until the end, which will not be happy, of course.
