If you're going to rewrite a story, this is how you do it! Much better than the disasters of last season, they took one of the more plodding and unimaginative stories (which some suspect Doyle didn't actually write, since there is very little "mystery" aspect to it) and made it an intriguing and entertaining story. The basic plot was fleshed out and augmented, and the plot twists that were added actually fit in to the story rather than confusing it. Well done!
