Title: Silver Service
Pairing & Rating: Methos/Amanda, Duncan/Amanda, implied Methos/Rebecca/Amanda, R for sexual content.
Why this must be read: This is an older story, and I can't say too much about it because it would ruin the twist at the end - this is my M. Night Shyamalan moment when it comes to fic. What I love was how it started as a romantic gift fic and then... boy, did it take a wrong turn at Albuquerque! And the end, the twist, it was terrific fun to be able to pull the rug out at the end and surprise the reader. This is still one of my favourites.
