Robert Fawcett “Sherlock Holmes”
From 1952 to 1953 Adrian Conan Doyle, Arthur Conan’s yongest son, wrote a total of one dozen “Sherlock Holmes” stories with John Dickson Carr.
Published in both Good Housekeeping and Colliers.
All twelve stories were illustrated by Robert Fawcett.
The stories were published in the book: The Exploits of Sherlock Holmes. Publication has ceased, though you can find the book through several third-party sellers.
