But you cannot make a plot work without another man, and he is usually a baritone, and he is called in the profession Fifth Business, because he is the odd man out. And you must have Fifth Business because he is the one who knows the secret of the hero's birth, or comes to the assistance of the heroine when she thinks all is lost, or keeps the hermitess in her cell, or may even be the cause of somebody's death. The prima donna and the tenor, the contralto and the basso, get all the best music and do all the spectacular things, but you cannot manage the plot without Fifth Business.
