The American claimant [sound recording] / by Mark Twain.

Enhanced descriptions from Syndetics:

Young Lord Berkeley has discovered that his family's title and wealth was obtained illegitimately, generations ago. He announces to his his father, the Earl of Rossmore, that he intends to travel to America, there to cede the Earldom to the rightful heir, along with all of its wealth, titles, and privilege, and to begin his life over again--"begin it right--begin it on the level of mere manhood, unassisted by factitious aids, and succeed or fail by pure merit or the want of it," he tells his father. As it happens, "The Rightful Earl" is an imaginative and enterprising attorney/inventor/office-seeker known as Colonel Mulberry Sellers. While less familiar to Mark Twain fans than Tom Sawyer, Connecticut Yankee, or Huckleberry Finn, The American Claimant is a delightful tale, told with Mark Twain's trademark American humor, his biting social satire, and his well-drawn characters.
