I have just checked Amazon and Google, but it doesn't look as if there is an English translation :/. I don't know how famous an author Muschg is (he's Swiss), or when books get translated, but in any case Der Rote Ritter would hardly have been a bestseller. It's too bad - I think you would have liked it.

Ach, the screenname thing... I should have been cleverer than to pick something obscure and medieval! But then I never thought I'd get friends who would actually know me by that name...
You can always call me by my real name, of course - that's the one of the lady in this icon, and a lot easier :).
