Grade Level: 2 and up Benny's curiosity, while staying in a fishing village, leads to capturing a swindler. In Schoolhouse Mystery, Benny is challenged by his friend Max to visit a dull, boring fishing town and find something, anything, in the way of adventure there. The Alden children and their grandfather do just that, with a little help. Between making friends and teaching at the local schoolhouse, the children notice a suspicious man who is hailed by the people in the town as something of a hero, offering money and gifts in exchange for very old things they believe are junk. The Aldens set out to find out what he's up to and who he is before he - and they - leave town!
