Alexander Graham Bell, Master of Sound (The Treasure Chest #7)

Maisie and Felix meet a young Alexander Graham Bell (the inventor of the telephone) in Edinborough, Scotland, just as he leaves for a year with his grandfather, an elocutionist, in London. When the twins get separated from Alexander, they join the thousands of orphans in the streets of Victorian London. Maisie becomes an orange seller and Felix a chimney sweep as they search the foggy streets for Alexander...and each other. Back at home, they cope with the upcoming wedding of Great Uncle Thorne, who makes them leave Elm Medona and return to the upstairs servants quarters.

Includes great non-fiction content with biographies of Alexander Graham Bell and Charles Dickens and Ann Hood's Favorite Facts from her research!
