About this book

What if a speck of dust tells you more about a crime than a confession?

In R. Austin Freeman's John Thorndyke's Cases, crimes that baffle the police meet a patient investigator. Dr. John Thorndyke is both a London barrister and a medical expert. From his chambers in the Temple, he studies the small physical traces that others overlook, asking not merely what seems likely, but what can be proved.

His friend and junior colleague, Dr. Christopher Jervis, tells these eight mysteries, learning the meaning of clues alongside the reader. The collection brings together puzzling events, worried clients, laboratory work and questions of legal proof. Behind the investigations stands Polton, whose skilled hands prepare the instruments and specimens that help turn observation into evidence.

What you’ll discover

  • Clues in ordinary things Follow dust, fibers and stains as small details become the key witnesses to a crime.
  • A mind that demands proof Watch Thorndyke test each claim with the care of both doctor and barrister.

  • The workshop behind detection Meet Polton, the craftsman whose instruments and prepared specimens support Thorndyke's patient investigations.

Los casos de John Thorndyke by R. Austin Freeman, the cover

From the 15-minute summary · Key idea 1

A lawyer and doctor who studies evidence

Dr. John Thorndyke lives and works in chambers in the Temple, the old legal quarter of London. He is both a barrister and a doctor, and he holds a post as a teacher of medical jurisprudence. That double training sets him apart from the police detectives of his day. He can read a wound as a physician would and then judge how it will stand up before a judge and jury.
