Another FicSwap entry, which I thought I'd posted already. Ah, well. I can't find the original brief, so I can't credit anybody, but if you know who it was I'll edit to include. It was something along the lines of 'A Swiss holiday goes very wrong'.
I also don't actually know anything about the inside of CERN, so I'm kinda... making it up as I go along, 'kay?
