It?s a dreadful shock for Horrid Henry when Perfect Peter is born, and despite his best ? or worst ? efforts, he can?t manage to get rid of him. As Peter gets bigger, Henry gets crosser. But the day comes when Henry inadvertently finds himself saving Peter from a big fierce dog, and discovers that it?s rather nice to be a hero.
