The Introduction to the Penguin Classics edition of Pudd'nhead Wilson gives voice to the widespread perception that the novel is in some ways a stunted classic—a book that fails to carry through its own profound and intriguing themes to their logical conclusion; preferring instead to accept the cheap victory of becoming a merely mechanical—if satisfying and gripping—detective story.
But if true, this is precisely part of the genius and power of the novel: because one of its great themes is precisely the stunting of personality under the force of social convention—something Twain himself knew intimately.
