R. Austin Freeman's first Dr. Thorndyke collection gathers eight short mysteries, opening with narrator Dr. Christopher Jervis's quiet seaside practice in the village of Little Sundersley — interrupted when a beach walk with his friend Dr. John Thorndyke turns up a set of peculiar footprints and a murdered body. Thorndyke, a "medico-legal expert" and one of fiction's earliest forensic scientists, applies real scientific method — trace evidence, medical analysis, careful observation — to unravel each case.
The stories that follow, including "The Moabite Cipher" and "A Message from the Deep Sea," established the template for the medico-legal detective story, grounding each puzzle in plausible forensic technique rather than pure deduction. A foundational work in the history of scientific crime fiction.
