A review by lieslindi
Conan Doyle for the Defense: The True Story of a Sensational British Murder, a Quest for Justice, and the World's Most Famous Detective Writer by Margalit Fox

You know from the outset that the man wrongfully imprisoned is released, but the ending struck a gut-punch from another direction. I did wonder whether he would go home to Germany. Good thing he didn't: he still had siblings there in 1939. He didn't in 1945.
