Books with title The Mystery of the Stolen Dinosaur Bones: The Boxcar Children Mysteries, Book 139

Henry, Jessie, Violet, and Benny used to live alone in a boxcar. Now they have a home with their grandfather, and they're fixing up their boxcar so they can ride it in the big Greenfield Founder's Day parade. There's just one problem: Someone has stolen the boxcar... with their dog Watch in it! If only they can find the missing boxcar, it will lead them to Watch. Can the Boxcar Children solve their most important mystery ever?

The four Aldens like visiting the large old museum owned by their grandfather's friend. But then Jessie sees a huge, scary shadow moving in the room where the dinosaur skeletons are on display. And bones from the enormous Tyrannosaurus rex disappear. They must find the missing bones and solve the mystery before an exhibit is scheduled to open - or there might not be a dinosaur exhibit at all!

The Boxcar Children have entered the Ruby Hollow Gem Mine’s annual gem-hunting competition. With a little instruction and the right gear, the Aldens have everything they need to become real rock hounds! They have a natural talent for rock-finding, and it’s not long before Jessie makes a fabulous find. But before she can enter her ruby in the competition, it disappears! Could there be a thief at the mine? Now, instead of digging for rocks, the Aldens are digging for clues. Who wants to win the contest so much that they would steal from the Aldens? The children don’t know, but they’re determined to find out!

The Boxcar Children have a chance to be in a real play - The Wizard of Oz! Jessie is chosen for the Cowardly Lion. Benny will play a munchkin. Even Watch has a part and all the Aldens are helping with the show. Then mysterious things begin to happen. Someone makes a threatening phone call and a costume is destroyed. Maybe the show won’t go on - unless the Boxcar Children can solve the mystery before opening night!
