Tom Sawyer and Huck Finn are saved from a crippling bout of spring fever when Aunt Sally writes and asks them to come to visit the family in Arkansas. As they set out on the steamboat downriver, though, Tom and Huck find themselves in yet another whirlwind adventure tracking down criminals and stolen diamonds, all to save the life of their beloved Uncle Silas.
The final Tom and Huck novella that Mark Twain completed before his death, "Tom Sawyer, Detective" is a fast-paced mystery, full of the wry humor and wit for which Twain is noted.
