The stories in Purity take the reader through cities and suburbs, apartments and streets, to find characters struggling to survive in modern society: a man has an outburst on a bus; a fugitive finds insight in a colour wheel; a social realist kills his friend with a hammer; a thief finds himself in books. And cleaners reluctantly go on cleaning. With gravity and humour, against the backdrop of a violent civilization, people are depicted as fallen, or waiting to fall, rendered by Tichy with the fury, compassion and emotional complexity of Kendrick Lamar. **2021 Nordic Council Literature Prize Finalist**
