I've been thinking over a plot idea since October and it finally seems to be coming together. However, I'm wondering if my plot can handle what I have coming for it. Here's a little background: Foster Kitch is fresh out of Boston University with a degree in Journalism. After a father and two older brothers than devoted their lives to football, Foster has decided to follow his own dreams, but still feels the need to prove himself. A company has agreed to sign him on, big time, if he can get a story worthy of the front page. Foster decides to follow a string of murders spanning more than two-hundred years, believed to be cult activity, and never solved (but always remaining open, as a new murder happens approximately once a month). He moves to New Orleans, LA, where the murders are currently taking place. Every muder in New Orleans has taken place in Audubon Park, so Foster rents a house just outside the park so he can be close to any developing news. Across the street from his rental house lives a mid-twenties girl named Emily Roux. Foster, new to the city, befriends Emily. She helps him do research, tells him everything she knows about the city, and generally is there for him to vent to or talk to when he needs a shoulder. Now, my main problem...Emily is the killer. She is one of the last living (*currently unnamed creatures*) that is initiated into this immortal world of killing humans to sustain life. Emily was initiated by her Mother and Grandmother, who were also some of these (*currently unnamed creatures*). They obviously appear human, act human, eat, sleep, etc., but they also kill. Emily moves around every 20 or so years to avoid suspiscion. Her mother is dead; her Grandmother is not. Do you think it will be possible to make a main character turn out to be the bad guy that my other main character is chasing? On top of all this, I have already decided on how these "creatures" can be killed. They can only be truly killed by someone they love and trust. So if Emily falls in love with Foster, and he figures out what she is...he could kill her. But I want to avoid all of the cliches.
