Claudia and the Mystery in the Painting — Ann M. Martin

America's favorite baby-sitters are detectives, too!

Claudia is helping Rebecca Madden prepare to sell her grandmother's house. Grandmother Madden was a famous artist, and finding more of her valuable paintings would help Rebecca and her family a lot. But everybody says it's impossible: Grandmother Madden destroyed all of her paintings before she died.

Claudia thinks everybody is wrong -- no artist would destroy her life's work. But if she's going to prove her theory, Claudia will have to work fast. Everything in the house will be sold in less than a week!
