A Polluted Font: The Chronicles of Hugh de Singleton, Surgeon, Book 16

When Hugh and Kate's new-born son is taken to the church to be baptized, they are astounded to find that the locked font is completely dry. The possibility of a leak is quickly ruled out, and just as Hugh is beginning to wonder if there may be a sinister explanation for the stolen holy water, Fr Robert is found lying motionless by the rood screen in a pool of blood... Meanwhile, parliament has passed a poll tax, stipulating everyone above the age of 14 is to be taxed equally. Folk are soon scrambling to find the money to pay and, inevitably, unscrupulous elements in society see an opportunity to feed off people's desperation and make some cash... But what connection can there possibly between this and events at Bampton?
