Harry Potter And The Methods Of Rationality

Chapter 49: Prior Information

A boy waits at a small clearing at the edge of the non-forbidden forest, beside a dirt trail that runs back to the gates of Hogwarts in one direction, and off into the distance in another. There is a carriage nearby, and the boy is standing well away from it, looking at it, his eyes seldom wavering from its direction.

In the distance, a figure is approaching along the dirt path: A man wearing professorial robes, trudging slowly with his shoulders slumped low, his formal shoes kicking up small clouds of dust as he walks.

Half a minute later, the boy darts another quick glance before returning to his surveillance; and this glimpse shows that the man's shoulders have straightened, his face unslackened, and that his shoes are now walking lightly across the dirt, leaving not a trace of dust in the air behind.

"Hello, Professor Quirrell," Harry said without letting his eyes move again from the direction of their carriage.

"Salutations," said the calm voice of Professor Quirrell. "You seem to be keeping your distance, Mr. Potter. I don't suppose you see something odd about our conveyance?"

"Odd?" Harry echoed. "Why no, I can't say I see anything odd. There seem to be even numbers of everything. Four seats, four wheels, two huge skeletal winged horses..."

A skin-wrapped skull turned to look at him and flashed teeth, solid and white in that black cavernous mouth, as though to indicate that it was just about as fond of him as he was of it. The other black leathery horse-skeleton tossed its head like it was whickering, but there was no sound.

"They are Thestrals, and they have always drawn the carriage," Professor Quirrell said, sounding quite undisturbed as he climbed into the front bench of the carriage, sitting down as far to the right as possible. "They are visible only to those who have seen death and comprehended it, a useful defense against most animal predators. Hm. I suppose that the first time you went in front of the Dementor, your worst memory proved to be the night of your encounter with He-Who-Must-Not-Be-Named?"

Harry nodded grimly. It was the right guess, even if for the wrong reasons. Those who have seen Death...

"Did you recall anything of interest, thereby?"

"Yes," Harry said, "I did," only that and nothing more, for he was not ready as yet to make accusations.

The Defense Professor smiled one of his dry smiles, and beckoned with an impatient finger.

Harry closed the distance and climbed into the carriage, wincing. The sense of doom had grown significantly stronger after the day of the Dementor, even though it had been slowly weakening before then. The greatest distance that the carriage allowed him from Professor Quirrell no longer seemed like nearly far enough.

Then the skeletal horses trotted forward and the carriage started in motion, taking them toward the outer bounds of Hogwarts. As it did, Professor Quirrell slumped back down into zombie-mode, and the sense of doom retreated, though it still hovered at the edge of Harry's perceptions, unignorable...

The forest scrolled by as the carriage rolled along, the trees moving past at a speed that seemed positively glacial by comparison to broomsticks or even cars. There was something oddly relaxing, Harry thought, about traveling that slowly. It had certainly relaxed the Defense Professor, who was slumped over with a small stream of drool coming out of his slack mouth and puddling on his robes.
