Uncle Daniel Bobbsey, who was Mr. Bobbsey's brother, and his wife, Aunt Sarah, lived in the country at Meadow Brook Farm. They had a ten year old son, named Harry, and he and Bert were great chums whenever they were together. The Bobbsey twins often went to the country, and also to the seashore, where their Uncle William and Aunt Emily, as well as their cousin Dorothy, lived, at a place called Ocean Cliff. You may read of the fun the twins had at these places in the country and seashore books. Bert, Nan, Flossie and Freddie also had fun at school, and when they went to Snow Lodge they had what were, to them, a wonderful series of adventures, and solved a strange mystery.
