Why this is on Radar
A Swedish dystopia from 1940 built around a truth serum, predating the better-known English-language equivalents.
A chemist invents a drug that removes the ability to lie, and the state immediately requisitions it. Boye's novel is one of the earliest fictional accounts of total surveillance through pharmaceuticals.
