Phil Gumshoe has a pretty laid back life, holding the steady job as Ponyville's only private investigator while researching and practicing magic and arcane lore. However, when two ponies are killed in what only seems to be an accident, he finds that he's bitten off far more than he can chew, as both the investigator of a murder committed by a powerful entity and the only hope of two fillies whose lives have been changed forever.
