The Full and Unpleasant Account of a Tortoise Most Vile and the Awful Business in the Basement

What's worse than a houseguest who never leaves?

One who's plotting evil in your basement.

Thaddeus J. Crepuscule may be small, charming, and fond of tweed, but Dot knows he's dangerous. The question is, can she outsmart him before he gets what he came for?

As strange inventions whirr to life and sinister plans unfold, Dot must rely on her courage (and an oddly motionless companion) to uncover the truth.

All will be revealed in this most unpleasant account, where bravery, mischief, and absurdity collide in the battle against a menace no bigger than a loaf of bread.
