Hi there, I'm Sherlock Bones.

Who is Sherlock Bones, you ask? Well, I don't like to brag, but my trusty side-kick Watts says I'm the greatest detective in our whole museum.

Don't you, Watts?

Watts . . . ?

Sherlock Bones and his sidekick, a stuffed parrot named Watts, live in a natural history museum. So when the precious Royal Blue Diamond goes missing, they are first on the case. What they don't expect is Grace, a silly, new-to-the-scene raccoon who keeps getting in the way. Even worse, Bones and Watts learn that if the diamond isn't recovered, the museum could (GASP!) close! Can they find the diamond before they're forced to find another home?
