The Wife of Martin Guerre by Janet Lewis

The Wife of Martin Guerre (first published 1941) is a short novel by American writer Janet Lewis based on the story of Martin Guerre, the 16th-century French peasant who apparently returned home to his wife after a long absence but was later revealed to be an impostor. The novel has its origins in research Lewis made into trials based on circumstantial evidence, after reading in-depth about famous trials turning on circumstantial evidence, which prompted her to write a pamphlet describing the risks of using it.
