Alistair Harper is a young, ambitious London gangster who plays a major role in three separate storylines of V for Vendetta. First, he is responsible for murdering Gordon, thereby triggering Evey’s attempt at revenge, and thus her imprisonment. Second, Harper is responsible for selling Rosemary Almond the gun that she uses to assassinate the Leader. Finally, Harper joins forces with Helen Heyer and plots to stage a military coup that will leave Helen’s husband, Conrad Heyer, the new Leader of England. Harper seems totally amoral, and has no qualms about betraying his friends and allies.
