The Aldens are spending the summer traveling on a houseboat! Throughout their journey, the children have the feeling that they’re being watched. Someone is watching them — and the thing that he wants is somewhere on their boat! He’ll stop at nothing to get it and it’s up to the Boxcar Children to figure out why!
The Boxcar Children Series was created by Gertrude Chandler Warner, a teacher, when she realized that there were few, if any, books for children that were both easy and fun to read. She drew on her own experiences in writing the mysteries. As a child, she had spent hours watching trains near her home, and often dreamed about what it would be like to live in a caboose or freight car. In each story, she chose a special setting and introduced unpredictable, unusual or eccentric characters, to help highlight the Aldens’ independence and resourcefulness. Miss Warner lived in Putnam, Massachusetts until her death in 1979.
