<p>Has anyone ever heard of this story?  I have just found a copy of it, but it is an undated photocopy of a typed manuscript, and the actual author is not named.  Josiah Holmes is the narrator character, identified as the son of Adrian Holmes, who is the son of Mycroft; this makes Josiah the great-nephew of Sherlock.  Obviously this is not canon, but I am not very familiar with the wide world of Sherlock Holmes pastiches, and I am wondering what I have found.  </p>
