Twilight is sent to Ponyville (for the first time) to investigate strange disappearances of the townsfolk. Unknown to her, but known to us, the town's favorite pink mare is behind it all. After meeting Applejack, Rainbow Dash, Rarity, and Fluttershy, as well as the murderer herself, Twilight tries to piece the evidence together. With her own life on the line, Twilight must work quickly to solve the case. Will she do it in time? Maybe. Maybe not. But, if she does... will the others even believe her? Things get even more difficult when Twilight falls in love with the pink mare...
