One of the Best Sherlock Fics Ever

I just finished reading this exquisite piece of fiction. This is actually the second-best Sherlock BBC fic I have ever read (the other one being quite possibly the saddest thing that I have ever read).

Be warned, it is slash (Johnlock or Sherlock/John, in this case) and 8 chapters long. However, the slash isn't graphic and it's well worth the read- even if slash isn't really your thing (Unless you detest it. I can't help you there if that's the case). The whole story centers on how Sherlock and John's relationship evolves as they follow a mystery designed to bring them to an important realization.

A Very Cold Case
