Frodo handed the book to Sam.

"What is it?" asked Sam.

"The Walking Hobbit's Guide to Middle-Earth. It's a sort of magical book. It tells you everything you need to know about everything. That's its job."

Sam turned it over nervously in his hands.

"I like the cover," he said. "Don't Panic. It's the first helpful or intelligible thing anybody's said to me all day."

"I'll show you how it works," said Frodo.

Frodo murmured a few elven words into the open book.

Ring Wraiths. Here is what to do to get rid of a Ring Wraith: forget it. They are the most unpleasant creatures on Middle-Earth – not actually evil, but focussed, purposeful, determined and persistent. They wouldn't even lift a finger to save their own grandmother from a Watcher in the Water unless she was wearing the "one ring".

The best way to get a drink out of a Ring Wraith is to stick your finger down his throat, and the best way to irritate a Ring Wraith is to feed his grandmother to a Watcher in the Water.

On no account allow a Ring Wraith to read poetry to you.

Sam blinked at it. "What a strange book."
