Harry Potter hanky-panky. Close readers of the fourth novel, Harry Potter and the Goblet of Fire, noticed a plot discrepancy…or was it a deliberate twist? Speculation abounded, until the mistake (as it turned out to be) was corrected, clumsily and with no public announcement, in subsequent printings. Fans criticize inordinate deadline pressures and inadequate prepublication editing, and wonder whether J.K. Rowling was involved in the inept correction at all. [My son and I had gotten a first printing of Goblet on the day of its release too, but we never noticed the error.]
