Heresy

"Well, the ingredients my dear.  Yours is the nearest English wood, once forest, to France.  Anne was educated at the French court.  France is the land of the great heresy.  Anne's home was Hever Castle, not far from here.  The Friary, there, right next door to your wood, was founded by Simon de Roches, a French Templar knight late back from the Holy Land, from where the great heresy most likely came."
