Hi! I've made a themed rec list of crossover case fics - crossovers between crime or medical procedurals and speculative fandoms, where the format and focus is on solving a case - over at my journal.


This is one of my favorite genres of crossover fic, and I'm excited to share my favorites with you all. Most of these will be on AO3, but a few are on other archives like A Teaspoon and an Open Mind, or Twisting the Hellmouth.

This list will be updated if/as I discover or remember more fic that fits the theme.

Please come take a look if you're interested!

Fandoms currently include CSI, Criminal Minds, NCIS, House, Numb3rs, Law and Order, Buffy, Supernatural, Highlander, Dark Angel, X-Men, Batman, Doctor Who, Torchwood, The Sandman, The Sentinel, Lucifer, Teen Wolf, and Murder She Wrote.

Link to story on Ao3.
Several years ago I promised selenak that I would write a Beatles story. It took a lot longer than I expected. This is a crossover between Doctor Who, Torchwood and the film Help! (1965), in which the Beatles played a fictionalised version of themselves. While the Beatles (and some other real people) appear in this story, it is the fictionalised versions that are portrayed in this story, not the real people. Major spoilers for Help! if it’s actually possible to spoil a 50+ year old film, and a lot of plot derailing.

Note to mods - need a Fandom: Help! or Fandom: Beatles tag if possible
