Von Igelfeld is the world's leading scholar on Portuguese irregular verbs, having written a majestic, nearly 1,200-page book on the subject. As one review says, "There is nothing more to be said on this subject. Nothing." But in other matters, von Igelfeld is not nearly so skilled. Whether haplessly playing tennis against an equally dreadful opponent, or committing his friends to swordfighting duels without their knowledge, von Igelfeld is somewhat naive in the ways of the world. Yet that does not stop him from having a go at life, and the results are always humorous.
