I really enjoyed this, I hadn't read the other parts so I've just caught up on the whole thing.

I'm not a fan of Lord of The Rings, but have read the first book and seen the films (yeah I know, not even sure why when I don't really enjoy any of it! ) so I knew the basic story but it worked anyhow even without really thinking about the crossover. I liked how you kept Jack and Ianto in character, it was a really clever way to use the LOTR plot but make it all very Torchwood.
Thanks for posting it all.
