Where is this fanfic you speak of?! Oh, and there's a section in ff.net now, very few fics though, one I especially like.

I never had a problem with the narrative to be honest, since from the beginning I've always expected it to be a full-blown mystery game. I love how nuanced the characters here are (heck, not just Ellen and Keats but even the minor ones if you've done their quests) along with their developments (which I appreciated for its subtlety).
