A meticulous investigative narrative examines the contested conviction of Oscar Slater, reconstructing the violent attack on an elderly woman, the discovery of evidence, and the responses of witnesses and police. The author lays out trial testimony, highlights inconsistencies and procedural problems, and critiques the Scottish legal handling that produced a divided jury verdict and a severe sentence. Interleaving factual reconstruction with legal argument, the work argues that the conviction rests on shaky evidence, calls attention to investigative oversights and social prejudices, and urges reconsideration of the case and of safeguards against wrongful punishment.
