After Sherlock, John, and the others receive an odd letter, things go spiraling quickly out of control- and John learns that nothing is ever as it seems- and there are some unexpected new members of the Holmes family along the way. A BBC Sherlock fanfiction, with a blend of elements from Stranger Things, Doctor Who, and Marvel's Agents of S.H.I.E.L.D. Expect weirdness and sci-fi. No, there will be no Johnlock, I don't ship that (I regret nothing). I honestly don't know at this point if there will be shipping, although I do like Sherlolly. This is my very first story. Enjoy!
