I wanted to pin a Fan Fiction but Pinterest was having a problem with it, so we have to use my blog as a stopping point. The story is called "The Hidden Photograph" and it takes place after The Empty Hearse and before The Sign of Three. A lot of Fan Fiction is rather silly, but this is a solid story. Feel free to leave a review.

Hope you all enjoy.
