Awesome!

Ohhhhh... I would love to find out what happens next. Pity this is (presumably) a one-shot. But the anticipation is good too.

This was great. Loved the line about elves and changelings bc it makes a lot of sense within that context

Mmm... the fever of the brain... so Sherlock. I do love how Holmes is willing to frame the Doctor to get a crack at him. *laughs* And Mycroft is so very very good about warning Sherlock off, only to actually encourage him. I love the detailing of John's boundaries...
