The Case of Oscar Slater, published in 1912 by Arthur Conan Doyle, is a non-fiction examination of the controversial murder trial of Oscar Slater, a Jewish immigrant wrongfully convicted of killing Miss Marion Gilchrist in Glasgow in 1909. Doyle critiques the Scottish legal system, highlighting flaws in the investigation and trial, including unreliable witness identifications and the prejudices faced by Slater. The book serves as a plea for justice, advocating for Slater's innocence and questioning the integrity of the judicial process that condemned him to death based on insufficient evidence.
