During the dissolution of the monasteries in the Tudor era, Matthew Shardlake is sent by Thomas Cromwell to investigate the death of a commissioner in a remote town of Scarnsea.

An eerie whodunnit adventure, set in 16th century England during the dissolution of the monasteries. Shardlake's sheltered life as a lawyer is turned upside down when Cromwell instructs him to investigate the murder of one of his commissioners at a monastery in the remote town of Scarnsea. The commissioner was gathering evidence to close the monastery and it is now imperative for Cromwell's own political survival that Shardlake both solves the murder and closes the monastery. He leaves Shardlake in no doubt that failure is not an option. Cromwell insists that he is accompanied by cocky, good-looking Jack Barak (Boyle) and Shardlake is left unsure whether Barak is an assistant, or Cromwell's spy. At Scarnsea, the duo are met with hostility, suspicion and paranoia by the monks who fear for their future and will seemingly stop at nothing to preserve their order.
