This reminds me how relieved I was about the German tourist family who showed up in Rivers Of London: scared, because it's a bad situation, but still comparatively calm and friendly in a slightly befuddled way. I honestly didn't expect it in a comical British novel. (Then again, the Horrible German Tourist is of course its own cliche, and as far as I know, just as deserved as its counterpart, the Horrible British Tourist.)

Also, I don't know if you've ever watched Flashforward - a horrible mess of a series that tried to cash in on the Lost phenomenon - but they both had an Operetta-friendly Evil Alt-Nazi, and his determined, probably Guilt-Ridden prison warden. Their names were, I kid you not, Geier and Krieger.
