R. Austin Freeman 
John Thorndyke’s Cases 

Dr John Evelyn Thorndyke is a fictional detective in a long series of novels and short stories by British author R. Austin Freeman (1862–1943). Thorndyke was described by his author as a ’medical jurispractitioner’: originally a medical doctor, he turned to the bar and became one of the first — in modern parlance — forensic scientists. His solutions were based on his method of collecting all possible data (including dust and pond weed) and making inferences from them before looking at any of the protagonists and motives in the crimes. (Freeman, it is said, conducted all experiments mentioned in the stories himself.) It is this method which gave rise to one of Freeman’s most ingenious inventions, the inverted detective story, where the criminal act is described first and the interest lies in Thorndyke’s subsequent unravelling of it.
