THE SCHOOlHOUSE MYSTERY (THE BOXCARCHILDREN #10) by Gertrude Chandler Warner, brings back memories. In the 1990's, this was a "Battle of the Books" choices and one of the favorites in my classroom of first, second and third graders. I kept my copy and reread it. This is the story of well-to-do Grandfather Alden and his four grandchildren, Henry, Jessie, Violet and Benny. They find and solve mysteries where ever they go. Benny's friend, Max, challenges them to vacation in a small remote New England fishing village, Port Elizabeth, where nothing exciting happens. They take the challenge and off they go. A strange man, Mr. Fred Willet, an antique dealer, is due to arrive in the village for a second summer. This for them, this is a red flag when they listen to the poor villagers happily relate how Mr. Willet gives them money and beautiful things in exchange for old worn out keepsakes. Upon befriending several village children with little schooling, the Alden children walk to the top of the hill to ask rich, old Miss Gray for the schoolhouse keys so they can teach the children in the mornings. The sardine factory calls them to work in the afternoons. Acting as detectives, the Aldens discover that Mr. Willet is taking precious books from the Gray Library and hiding them, as well as the villagers' old coins and antique goods behind the library's bookshelves. Upon being caught the villain faces jail time and the Alden children are the village saviors. This is an intriguing story that holds the reader's interest. The colorful cover and black and white drawings throughout the book, add to the storyline for young readers (ages 6-9). For me, the story shows its age--a 1965 copyright. I'm not sure the depiction of the poor, uneducated village people who are at the mercy of a swindler and saved by the rich, would work today. All in all, though, it is a well written children's mystery and I did enjoy rereading it.
