La Vallée de la peur
Reports of McParland's success against the Molly Maguires came to the attention of Sir Arthur Conan Doyle, author of the Sherlock Holmes detective novels. Conan Doyle wrote McParland into "The Valley of Fear", creating an encounter between the fictional Sherlock Holmes, and a character whose history loosely recalled McParland's experiences with the Molly Maguires.
