When a new case comes to Sherlock, he and John may be in over their heads. While they're trying to track serial killer, the Winchesters are on a hunt for an angry spirit.

If you haven't read my first story I'd highly recommend that you do, I'm not sure how much you'll understand if you don't, but I don't run your life. With Sherlock and John getting into hunting, they may be in over their heads with this new case. It's up to Sam and Dean to get them out, or all of their heads are on the chopping block.
