Quincy and Danny go to the tack and, while there, see a horse go wild in the stables. The horse kills one of the jockeys but, after completing his autopsy, Quincy thinks that it wasn't an accident! That someone murdered the man and tried to make it look as if the horse killed him. The problem Quincy has though is to actually prove his theory, and not even the purchasing of some horse hooves and the unusual step of autopsying a horse can help him. Though Asten has fits about the cost of both these steps to find the truth!
