An occasional feature of published pages about John Watson
Several people have addressed the question of who wrote “His Last Bow”, “The Mazarine Stone” and the second half of A Study in Scarlet because they are written from an unusual third person perspective. For many, the obvious fact is they were written by someone other than Watson, and, therefore, they are not to be trusted. But there is nothing so deceptive as an obvious fact.
These stores were all written by Watson. However, he makes it clear when he is not reporting from personal experience by turning to the third person. It is his way of letting us know that while the facts are accurate to the best of his knowledge, that knowledge is second hand and may be liable to error.
