I spent the better part of this evening trying to track down a Due South story (RayK/Fraser). I don't remember the title or author. No that would be to easy. I do remember the story. It's post end of the series. Fraser and Ray are back in Chicago and Ray is reconnecting with his life prior to the undercover work. An old friend of his transfer in and they are assigned to work together. Fraser can't stand her. He is totally jealous. I think Ray and Fraser are in a relationship at the time or are starting one.
Driving me nuts. Nuts!!!! I should go to bed. I have to go to work tomorrow.
ETA: The story is
