A Fourtris Story: Spies

Hi I'm Beatrice Prior but I am usually called Tris. I am apart of the FBI and now in an undercover mission. My mother was killed when I was young. Still, no one has found the murderer. I know he's still alive because he knows where I am and says he's coming after me. The captain has moved me to become a spy. My father and brother are still alive but I fear is in great danger. I don't know what to do, protect family or actually do my job. I have no idea who are my friends and who are my enemies. But for now, they are all traitors.
