This is a lovely Sherlock story:
http://seriousfic.livejournal.com/503757.html#cutid1 It's from Harriet's POV, with brief appearances by other canon characters and is a lovely look at a possible ending to the Great Game (it involves character death, FYI). We never met Harriet in the show, and probably never will, and the author doesn't pretend that Harriet and John had some deeper relationship than the awkward one the show sketched out. Still, that they were family is clear and the fact that Harriet knew next to nothing of his current life didn't shake that.
