"Your turn Harry," said Amelia.

Harry raised his wand, ready, but --

"Here!" shouted Professor Lupin suddenly, hurrying forward. Crack!

The legless spider had vanished. For a second, everyone looked wildly around to see where it was. Then they saw a silvery-white orb hanging in the air in front of Lupin, who said, "Riddikulus!" almosi lazily.

Crack!

"Forward, Neville, and finish him off!" said Lupin as the boggart landed on the floor as a cockroach. Crack! Snape was back. This time Neville charged forward looking determined.

"Riddikulus!" he shouted, and they had a split second's view of Snape in his lacy dress before Neville let out a great "Ha!" of laughter, and the boggart exploded, burst into a thousand tiny wisps of smoke, and was gone.

"Excellent!" cried Professor Lupin as the class broke into applause. "Excellent Neville. Well done, everyone.... Let me See... five points to Gryffindor for every person to tackle the boggart -- ten for Neville because he did it twice... and five each to Hermione and Harry and five points to Hufflepuff."

"But I didn't do anything," said Harry.

"You and Hermione answered my questions correctly at the start of the class, Harry," Lupin said lightly. "Very well, everyone, an excellent lesson. Homework, kindly read the chapter on boggarts and summarize it for me... to be handed in on Monday. That will be all."
