An important discovery puts Roger the Chapman's life in danger . . . - In the autumn of 1483, Roger goes on an errand of mercy to Hereford, where he is caught up in the Duke of Buckingham's rebellion against the new king, Richard III. Roger takes refuge in Tintern Abbey, but on his return to Bristol, a murder and a series of house robberies lead him to the eventual discovery of the treasure stolen from the abbey on the night he was there. It also means great danger, not only for himself, but a member of his family.
