In 1970, Harold Stamp, a retarded 20-year-old, was convicted on disputed evidence and a retracted confession of brutally murdering his grandmother. Less than three years later he is dead, driven to suicide by isolation and despair.

He finds alarming disparities in the evidence and has little doubt that Stamp's conviction was a terrible miscarriage of justice. But how far is Hughes prepared to go in the search for justice? Is the forgotten story of one friendless young man compelling enough to make him leave his books and face his own demons? And with what result?
