Ostensibly the adventures of Sherlock Holmes were recorded by his friend John Watson. But of the 60 canonical tales, two (“The Adventure of the Mazarin Stone” and “His Last Bow”) are told in the third person. Who wrote these? Sherlock’s brother Mycroft? One of Watson’s wives? Watson himself, strangely? Arthur Conan Doyle?

In The Annotated Sherlock Holmes, William Stuart Baring-Gould writes only, “There has been much controversy as to the authorship of these two adventures.”
