Hair, Hair, Everywhere

Someone's been digging up Mrs. Ruston's tomatoes. She thinks it's Noelle's dog, Rover, and unless Noelle can find the real thief, Rover's in big trouble.

It's the hairiest case yet for Mr. Merlin's Third-Grade Detectives. Hair in Mrs. Ruston's tomato patch, hair in Amber Lee's hamburger -- can Noelle and Todd comb through the evidence and solve the mystery?

The Third-Grade Detectives are looking forward to their field trip to a local art museum, where a priceless fifteenth-century statue of Joan of Arc is on loan from a Paris museum. But when they arrive, they discover that the statue has been stolen
The police quickly find the statue -- smashed into pieces and thrown in a Dumpster. Why would someone steal the statue only to destroy it? It looks like a new case for the Third-Grade Detectives -- even if the museum director doesn't seem to want their help.

Eight-year-old Jack and his younger sister Annie find a magic tree house, which whisks them back to an ancient time zone where they see live dinosaurs.
