The Aldens solve a mystery at the old Trap-Door Theater.
Gertrude Chandler Warner grew up in Putnam, Connecticut. She wrote The Boxcar Children because she had always dreamed about what it would be like to live in a caboose or a freight car-just as the Aldens do. When readers asked for more adventures, Warner wrote more books-a total of nineteen in all. After her death, other authors have continued to write stories about Henry, Jessie, Violet, and Benny Alden, and today The Boxcar Children® series has more than one hundred books.
