No sooner than the very next day after we heard from Percy, it came out that Umbridge had been appointed Hogwarts" first ever High Inquisitor. Like the other Muggleborns, I had a hard time keeping from giggling as I remembered the famous Monty Python sketch, and I'm sure I heard, more than once: "No one expects the Hogwarts Inquisition!" under someone's breath. However, this was a new, ominous development. Apparently a "High Inquisitor" was roughly the same sort of thing as a "political commissar" in the old Warsaw Pact armed forces---in other words, a person whose primary loyalty was to the Ministry who could, if need be, override Dumbledore's authority. I wonder if Fudge ever read about the Communists? If so, using one of their old dodges was a sneaky move, since most magical folk would sooner be caught reading Pervert Monthly than anything to do with Muggles. Yet another weakness to exploit.
