In the third book of the Capital Mysteries—an early chapter book mystery series featuring fun facts and famous sites from Washington, D.C.— KC and her friend Marshall explore the Smithsonian, the most famous museum in the world. The money to build it was given to Washington, D.C., over a hundred years ago, but now one man is claiming that money should be his. KC and Marshall think they can prove Mr. Fisher is a big liar. But if they are wrong, the Smithsonian will belong to him! Each book highlights one of the famous museums, buildings, or monuments from the Washington area. Parents, teachers, and librarians agree that these highly collectible chapter books are perfect for emerging readers and any kid who loves mysteries!
