Adrian Conan Doyle

For people who check facts
Adrian Conan Doyle (1910-1970) was the youngest son of Arthur Conan Doyle, and his father's literary executor. Adrian Doyle was described as a race-car driver, big-game hunter, explorer, and writer. He was born in Crowborough, England and died in Geneva, Switzerland.

Either alone or with the assistance of John Dickson Carr, Adrian Doyle produced additional Sherlock Holmes stories. The basis of his production was to complete the tales referenced in his father's stories, but which his father had never written. These Sherlock Holmes tales were written in 1952 and 1953, but have been republished subsequently. Other authors have also written Sherlock Holmes stories based on the same references within the original tales.
