Chapter ten: Hallowe'en
The shouting and the echoes seemed to be driving the troll berserk. It roared again and started towards Ron, who was nearest and had no way to escape.
Harry then did something that was both very brave and very stupid: he took a great running jump and managed to fasten his arms around the troll’s neck from behind. The troll couldn’t feel Harry hanging there, but even a troll will notice if you stick a long bit of wood up its nose, and Harry’s wand had still been in his hand when he’d jumped - it had gone straight up one of the troll’s nostrils.
Howling with pain, the troll twisted and flailed its club, with Harry clinging on for dear life; any second, the troll was going to rip him off or catch him with a terrible blow with the club.
Hermione had sunk to the floor in fright; Ron pulled out his own wand - not knowing what he was going to do he heard himself cry the first spell that came into his head: ‘Wingardium Leviosa!’
The club flew suddenly out of the troll’s hand, rose high, high up into the air, turned slowly over - and dropped, with a sickening crack, on to its owner’s head. The troll swayed on the spot and then fell flat on its face, with a thud that made the whole room tremble.
"You always this quiet?"
