What if thoughts are no longer free - the rediscovery from Sweden: the great dystopian novel by Karin Boye, first published in 1940, more relevant than ever.

With a truth drug, chemist Leo Kall has found a way into the souls of his fellow citizens. The state's new interrogation method takes control over the people. Anti-state thoughts are exposed, all citizens are brought into line, and marriages are typically formed as mere partnerships to provide the state with children. Yet secretly, resistance is stirring. Some people seek meaning in life beyond the official doctrine. Leo Kall also begins to doubt and questions his role as a loyal comrade. Nevertheless, he chooses a dangerous path. He is determined to find out if his wife is having an affair, even if it means resorting to a perilous experiment.
