The Underpants of Chaos

Emil’s Review:

I like this book as each chapter is written from the different two characters, and I like the crazy things that happen to them when the shivers came.

Something BAD is happening at Little Strangehaven Primary. What are the peculiar SHIVERS that keep striking the school, bringing Strangeness in their wake -from uncontrollable ballroom dancing to an attack by military chickens?Spy-detective Agatha Topps is determined to find out. She's the only person who doesn't forget the Strangeness as soon as it's over.

At least, until new boy Lenny Tuchus turns up and remembers too. Their spy-detectoring leads them to the Book of Chaos, an ancient text which has been hidden away in the Room of Forbidden and Dangerous Books.
