Into the Hills

When Sherlock Holmes barges into their living room at 221B Baker Street covered in blood and wielding a harpoon, John Watson dismisses the incident. But as it turns out, the case of the dead pig is still waiting to be solved, and doing so may take a heavy toll on both of them... A canon-compliant extra episode. Casefic, Drama, Angst and H/C. Gen; no pairings.
