"Gertrude Chandler Warner discovered when she was teaching that many readers who like an exciting story could find no books that were both easy and fun to read. She decided to try to meet this need, and her first book, , quickly proved she had succeeded. Miss Warner drew on her own experiences to write the mystery. As a child she spent hours watching trains go by on the tracks opposite her family home. She often dreamed about what it would be like to set up housekeeping in a caboose or freight car--the situation the Alden children find themselves in. When Miss Warner received requests for more adventures involving Henry, Jessie, Violet, and Benny Alden, she began additional stories. In each, she chose a special setting and introduced unusual or eccentric characters who liked the unpredictable.
