Blessings (слэш)

This is the final part of the Random Strangers series. It started with a letter addressed to a random stranger, ends here, at Reichenbach. The narrator is John, speaking to Sherlock throughout. Some parts are memory, others are reality, and others blend the two. John wrestles with his past while trying to solve the problem of Moriarty.
This will make more sense if you have read the previous parts. There are echoes here from those stories.
