"This way," said Harry, pointing down a stone passageway, which was the only way forward.

All they could hear apart from their footsteps was the gentle drip of water trickling down the walls. The passageway sloped downward, and Harry was reminded of Gringotts. With an unpleasant jolt of the heart, he remembered the dragons said to be guarding vaults in the wizards' bank. If they met a dragon, a fully-grown dragon — Norbert had been bad enough...

"Can you hear something?" Ron whispered.

Harry listened. A soft rustling and clinking seemed to be coming from up ahead.

"Do you think it's a ghost?"

"I don't know... sounds like wings to me."

"There's light ahead — I can see something moving."

They reached the end of the passageway and saw before them a brilliantly lit chamber, its ceiling arching high above them. It was full of small, jewel-bright birds, fluttering and tumbling all around the room. On the opposite side of the chamber was a heavy wooden door.

"Do you think they'll attack us if we cross the room?" said Ron.

"Probably," said Harry. "They don't look very vicious, but I suppose if they all swooped down at once... well, there's no other choice... I'll run."

He took a deep breath, covered his face with his arms, and sprinted across the room. He expected to feel sharp beaks and claws tearing at him any second, but nothing happened. He reached the door untouched. He pulled the handle, but it was locked.
