Who's murdering the ministers of Mass. Bay? Four are dead and Cotton Mather thinks he's going to be the next victim. It's up to Mather's cousins Hetty and Creasy to catch the craven killer of Colonial Clergermen. Is it the Royal Governor or his Secretary who threaten to make the Boston colonists into slaves? Is it old Gammar Pisspot, arrested as a witch? Or is it the mad Quaker Gabriel who prophecies the death of the Dissenters? Or has the West Indies servant Zillah bewitched them all? With the help of Hetty's pet pig Priscilla, the cousins battle political oppression, mob mayhem, and voodoo violence to unmask the murderer.
