Question for those of you who've read THE COUNT OF MONTE CRISTO, I think my Kindle version might be missing some pages. In the chapter where Albert & Franz are talking with the countess in her box at the opera, with no mention of Albert, Franz suddenly takes the countess home before the show is over then returns to his hotel where Albert says, "You're back early." Is that author error or do I have a faulty book?
