Numb3rs Fanfic Finders

I'm looking for any fic in which Don plays a big part [or at least not a minor one] that also have supernatural elements to it

vampires, werewolves, magic...
anything of this nature in the /numb3rs/ universe
or perhaps Don goes away from la and comes across it then
whatever as long as it is supernatural and has don in it

and no i don't mean crossovers with that tv show by the name supernatural though if it falls more heavily on the /numb3rs/ side then i'll give it a try

thanks
