Austin Freeman

Richard Austin Freeman (1862–1943) was an English writer of detective fiction, best known as the creator of Dr. John Thorndyke, a medico-legal investigator whose scientific methods revolutionized the genre. Born in London, Freeman trained as a pharmacist and physician before serving as a colonial surgeon on the Gold Coast (modern-day Ghana), an experience that later shaped his travel writing and early fiction. He began his literary career co-writing novels with John James Pitcairn under the pseudonym Clifford Ashdown.

Freeman is widely credited with inventing the "inverted detective story," a format in which the criminal and the methods of the crime are revealed to the reader at the start, and the suspense lies in watching the detective unravel the case. His first inverted tale, "The Case of Oscar Brodski," appeared in The Singing Bone (1912).

His major works include The Red Thumb Mark (1907), which introduced Dr. Thorndyke; The Eye of Osiris (1911); The Mystery of 31 New Inn (1912); A Silent Witness (1914); The D'Arblay Mystery (1926); Mr. Pottermack's Oversight (1930); and The Jacob Street Mystery (1942). Praised for rigorous plotting and authentic forensic detail, Freeman strongly influenced the Golden Age of detective fiction and later writers such as Dorothy L. Sayers.
