Hannibal is John's father

[jaddistiger.livejournal.com]

Just like the title said, I'm looking for a story where Hannibal is John's father and Sherlock finds out after they meet on a case. From what I remember John helped his father with killing when he was a kid and that's how he got his training as a doctor. I can't remember what site I found this on, but probably Fanfiction.net or A03.
