The Devil Wears Tartan came to life because of something I read about Chinese history. The article I was reading led to another link, which led to another, and like magic, the plot was born.
Marshall Ross and Davina McLaren are both flawed characters (love flawed people) who have made mistakes and paid dearly for them. They are forced together by circumstances, but Fate, instead of being capricious in this instance, rewarded each of them with the other. Marshall found in Davina a woman who could believe in him, and Davina found in Marshall a challenge, and someone who deserved both her loyalty and her love.
