Medium-Part One Of Two

My name is Matthew and I'm in the strangest love triangle ever. You see I'm a medium and I talk to the dead. My girlfriend passed away and to see her again I learnt to use the power I have. Now there's a beautiful girl who helps people like I do and who is now part of a team of us. This team hunts down the bad and helps the good ghosts but there's a killer out there and a beast who could both be me.
