There's a new craze sweeping Foghorn Elementary: A trading card game called Butt Blast, and the player with the stinkiest deck wins!

But when everyone's most precious cards start vanishing from under their noses, it doesn't take a master detective wannabe like Billy to realize there's a thief on the prowl.

And a mystery to solve!

For as long as Billy Farthing can remember, he's always wanted to be a private detective. Or maybe a cop. Possibly both. The only problem is that the sleepy town of Foghorn isn't exactly crawling with crime... It's hard to keep your dreams of being a detective alive when nobody even bothers locking their doors at night.

So when an honest-to-goodness mystery springs up right in Billy's elementary school, it's an opportunity too good to miss! But can Billy, a boy whose only skills are his explosive farts and his penchant for getting into trouble, crack the case? Or will the culprit vanish like a fart in the wind?

The first fart had only been a warning shot...

Billy vs. The Butt Blast Bandit is a mystery for readers who like their villains vile, their heroes odorous, and their farts pungent.
