Extracts from the Usborne Young Readers Edition of The Phantom of the Opera, which features Carlotta eating chocolates in bed, Count Raoul, water that magically bursts into flames, and Madame G. Not Madame Giry, just simply Madame G (in da opera house).
And poor Phantom only takes Christine under the opera house because he only wants a wife and a family…and he signs his notes “P”, not “O.G.” - these are both signed “P”, who the hell is he? (Still goes, I guess.)
I found this book at the Opera Garnier gift shop on my trip to France. I almost bought it, but I ended up buying a paperback version of the original Leroux novel (in French. I think my spoken French is a little better than my reading of French.)
