Shelby & Watts

"Violet the bear has awoken early from her hibernation, but she doesn't know why. She's called on Shelby & Watts to solve the case before her son, Theodore, is roused from his hibernation, too. With Shelby's deductive skills and Watts's scientific know-how, they'll leave no stone unturned or question unanswered"--Back cover.

"Meet Shelby & Watts! Shelby loves a good mystery. And her best friend, Watts, is never without his encyclopedia. When Shelby gets a letter from Fred the hermit crab claiming that all the shells are missing from the beach, she and Watts are just the duo to help him. With Shelby's deductive skills and Watts's scientific knowledge, there's no case the two of them can't solve--one environmental mystery at a time!"--From the publisher's web site.
