This Guy Thinks He's Found an Unpublished Conan Doyle Sherlock Holmes Story

To be fair, it's possible that it's a real long lost Sherlock Holmes story by Sir Arthur Conan Doyle, it's just not very probable.

The story in question is 1,300 words in length and appeared in a 1903 pamphlet for a bazaar that was held to raise money for a bridge restoration in the town of Selkirk, Scotland.  Sir Arthur Conan Doyle was a guest of honor at the bazaar, and provided some funding for the bridge restortation, but there's no mention of him writing a story for it.  The pamphlet story is unsigned, and is most likely a part of a series of three "Notable Inerviews" written for the bazaar.  The story opens with a nod to the previous two interviews, and it's terribly unlikely that Conan Doyle wrote those interviews as well.  It's more likely that someone else wrote the story as a nod to Conan Doyle's attendance. 

"Sherlock Holmes." — DISCOVERING THE BORDER BURGHS, and, BY DEDUCTION, the BRIG BAZAAR was found by historian Walter Elliot, who has apparently had it for 40-50 years, and brought it out of storage upon hearing that the bridge is to again be restored.  You can read the text in full here.
