The fourth in the increasinlgy, misleadingly titled: "Trilogy of Errors". If you've bother to read the first three, this one will surely coax a titter out of you. But, if you haven't, don't fret. Harry is currently teaching at Hogwarts, which has completely Re-staffed as of the new year of 2007(odd plot point, eh?). If you want to read about what the Trio might be doing in a more cynical, deviant understanding, read this.
