Thank you for the work you put into this post, and a chance to get a glimpse of a story I otherwise would never see. Still, this sounds better as an idea than in execution. The art is solid but a bit awkward. It's always hard to tell how writing is that has been translated into English (such a difficult thing to do... getting the gist of the original and making it seem natural in the new language). I once read a lengthy article comparing various translations of Jules Verne, and sadly realized that unless I learned French myself, I would never be able to fully appreciate a great writer.
Still, this is fascinating. One of the very first and greatest super-heroes meeting one of the most complex and interesting men in history, teaming up to do a pastiche of THE HOUND OF THE BASKERVILLES...! It makes me realizes how much there is in European comics that I've missed. Thanks again.
