The Autobiography of Mark Twain
The Autobiography of Mark Twain contains a litany of people who cheated him and losses on his investments near the end of his life.
Nothing ever happened to Mark Twain in a small way. His adventures were invariably fraught with drama. Success and failure for him were equally spectacular. And so he roared down the years, feuding with publishers, being a sucker for inventors, always learning wisdom at the point of ruin, and always relishing the absurd spectacle of humankind, which he regarded with a blend of vitriol and affection.
