Write about a character who appears to be the good guy, when he or she is really the bad guy all along. No one realized until it’s too late for them. Who is brave enough to fight off this bad character? Will it be the character that everyone thought was the real bad guy but was actually the good guy? Or will it be a character who is known as a coward up until now? How does he or she prove his or herself to everyone? What happens that causes the bad guy to slip up? How does his or her bad schemes come to an end? How many have died before the mystery was solved? And what was the bad guy’s motive(s)? What caused them to become the psychopathic killer he or she turned into?
