Being a candymare is a safe, easy lifestyle...usually.

But when Bon Bon starts getting threatening letters from a stalker, her wife, Lyra Heartstrings, contacts Phillip Finder to try to identify the stalker. Aided by Flash Sentry, Phillip comes to suspect that Bon Bon's letters may be connected to a series of high-risk burglaries in Ponyville recently.

Constructive criticism appreciated.
