Sherlock and John are at a murder scene when John finds a suspicious bottle. Instead of showing it to Sherlock as evidence, he becomes fascinated by it and decides to figure out what it is. When he finds out, who will he use it on?
I know I've said it before but I suck at descriptions, but please enjoy. It's based of the song Love Potion No. 9 and not the movie. (Although it's a good movie)
