Purgatori on the Nile! It's time for a game of crocodile-and-mouse in Africa with the coven of Purgatori's least favorite witches, and the river's going to run red with someone's blood. Purgi knows that killing her enemies isn't a problem -- it's what they're doing to her mind after they're dead that might very well destroy her.
Maybe there really is no way for her to win this fight. Maybe it's time to change the rules of the game.
