In the autumn of 1483, Roger goes on an errand of mercy to Hereford, where he gets caught up in the Duke of Buckingham's rebellion against the new king, Richard III.

Taking refuge in Tintern Abbey, Roger learns of an ancient hiding-place linked to events of over a century and a half ago. But on his return to Bristol, a murder and a series of house robberies lead him to the eventual discovery of the fabulous treasure stolen from the abbey on the night he was there.

It also means danger, not only for himself, but a member of his family.
