The novel begins as the narrator (later identified as Huckleberry Finn) states that we may know of him from another book, The Adventures of Tom Sawyer , written by “Mr. Mark Twain.” Huck quickly asserts that it “ain’t no matter” if we haven’t heard of him. According to Huck, Twain mostly told the truth in the previous tale, with some “stretchers” thrown in, although everyone except Tom’s Aunt Polly, the Widow Douglas, and maybe a few other girls tells lies once in a while.
We learn that Tom Sawyer ended with Tom and Huckleberry finding a stash of gold some robbers had hidden in a cave. The boys received $6,000 apiece, which the local judge, Judge Thatcher, put into a trust The money in the bank now accrues a dollar a day from interest. Then, the Widow Douglas adopted and tried to “sivilize” Huck. Huck couldn’t stand it, so he threw on his old rags and ran away. He has since returned because Tom Sawyer told him he could join his new band of robbers if he would return to the Widow “and be respectable.”
