A collab story written by CanterlotGuardian and P3RROHAMBRE.

Derpy Hooves is the local mail-mare of Ponyville, a sister, and a pony that loves her town. When crime begins to rear its ugly head in Ponyville, Derpy of course notices and wants it to be stopped, but what do you do when no one will listen? When no one is willing to take action?

You take matters into your own hooves.

Taking on the persona of Mare-Do-Well, Derpy will fight crime and stop those who threaten her beloved town.
But what starts as petty crime, Derpy will soon realize that there is something much bigger and more dangerous than she could imagine.
Can she stop this threat? Or will she fail and doom not just Ponyville, but all of Equestria?

Only one way to find out…
