On a bitter winter evening in 1356 Matthew Bartholomew & Brother Michael arrive in Lincoln
- Michael to accept an honour from the cathedral & Bartholomew to look for the woman he wants to marry. It is not long before they learn that the friary in which they are staying is not the safe haven they imagine
- one guest has already been murdered. It soon emerges that the dead man was holding the Hugh Chalice a Lincoln relic with a curiously bloody history. Bartholomew & Michael are soon drawn into a web of murder lies & suspicion in a city where neither knows who can be trusted.
