Summary
"The Aldens are making the journey to their Aunt Jane's house for an overnight bicycle trip. On their first night, though, the children are caught in a rainstorm. They have to take shelter in an old, abandoned house. There, a most unusual mystery--a lost dog--finds them! Can the boxcar children figure out the mystery of where the dog belongs?"--P. [4] of cover.
