"Get out of the way," snapped Ron, taking a swipe at Peeves this was a big mistake.

"STUDENTS OUT OF BED!" Peeves bellowed, "STUDENTS OUT OF BED DOWN THE CHARMS CORRIDOR"

Ducking under Peeves, they ran for their lives, right to the end of the corridor where they slammed into a door - and it was locked.

"This is it!" Ron moaned, as they pushed helplessly at the door, "We're done for! This is the end!" They could hear footsteps, Filch running as fast as he could toward Peeves's shouts.

"Oh, move over," Hermione snarled. She grabbed Harry's wand, tapped the lock, and whispered, 'Alohomora!"

The lock clicked and the door swung open - they piled through it, shut it quickly, and pressed their ears against it, listening.
