Numb3rs Fanfic Finders

I've been wondering whether there were any historical AUs set during WWII, for example with Charlie working as code breaker, or Larry as part of the Manhattan project, or Don as soldier... Any scenario set during WWII, though in case the story cast Charlie or Don not as part of the Allied forces but as Jewish Holocaust victims or the like, it would have to be well researched to not squick me by using concentration camps as main story setting in distorted ways or for cheap melodrama effects. I'm not into incest fic, but otherwise I'm not particular about pairings.
