Read the following excerpt from The Jungle Book by Rudyard Kipling.

"He has no right!" Father Wolf began angrily. "By the Law of the Jungle he has no right to change his quarters without fair warning. He will frighten every head of game within ten miles; and I—I have to kill for two, these days."

"His mother did not call him Lungri [the Lame One] for nothing," said Mother Wolf, quietly. "He has been lame in one foot from his birth. That is why he has only killed cattle. Now the villagers of the Waingunga are angry with him, and he has come here to make our villagers angry. They will scour the jungle for him when he is far away, and we and our children must run when the grass is set alight. Indeed, we are very grateful to Shere Khan!"
