The relic master : a novel
(Book)

1517. Dismas is a relic hunter who procures "authentic" religious relics for wealthy and influential clients, and is as honest as any relic dealer can be. When Dismas and his artist friend Dürer conspire to manufacture a shroud to sell to the unsuspecting noble, Dürer's reckless pride exposes Cardinal Albrecht's newly acquired shroud as a fake, the Cardinal puts Dismas and Dürer in the custody of four loutish mercenaries and sends them all to steal Christ's burial cloth-- the Shroud of Chambéry-- Europe's most celebrated relic.
