Christmas Book - The Stinky Christmas Mystery

There's a stinky, smelly stench about...

It's all around the house.

It's outside in the street, It's even at the beach.

The smell's so stinky it's making Ellie and Elijah turn green.

No matter how hard they wave their hands or grip their noses the smell won't go away.

Will Ellie and Elijah be able to sniff their way to solve the smelly mystery or will they be left in a big stink?
