Conan Doyle for the Defense: How Sherlock Holmes's Creator Turned Real-Life Detective and Freed a Man Wrongly Imprisoned for Murder

A sensational Edwardian murder. A scandalous wrongful conviction. Sir Arthur Conan Doyle to the rescue—a true story.

After a wealthy woman was brutally murdered in her Glasgow home in 1908, the police found a convenient suspect in Oscar Slater, an immigrant Jewish cardsharp. Though he was known to be innocent, Slater was tried, convicted, and consigned to life at hard labor. Outraged by this injustice, Arthur Conan Doyle, already world renowned as the creator of Sherlock Holmes, used the methods of his most famous character to reinvestigate the case, ultimately winning Slater’s freedom.

With “an eye for the telling detail, a forensic sense of evidence and a relish for research” (The Wall Street Journal), Margalit Fox immerses readers in the science of Edwardian crime detection and illuminates a watershed moment in its history, when reflexive prejudice began to be replaced by reason and the scientific method.
