A crime wave is gripping the sleepy town of Apple-Morepone. Then "Rainbow" Dash of the City Watch meets a batpony (adopted) named Carrot. The town will never be the same. (An homage to the City Watch of Terry Pratchett's Discworld novels!)
Nightmare Moon's about to return and Equestria needs a savior, but don't worry: Celestia's got everything under control. Just as long as Twilight goes to Ponyville on time, and not to Moondancer's party instead--but why would she ever do that?
There are three things that ponies love more than anything else and which will inevitably end up killing them if not enjoyed in moderation: baked goods, sunny days, and the magic of Harmony. This story is about all of these but mostly the last.
