July 1556. Jack Blackjack spends the night at a Devon tavern, agrees to a game of dice - and ends up accused of murder. To make matters worse, the dead man was the leader of the all-powerful miners who rule the surrounding moors. But who would frame Jack for murder . . . and why? Jack realises that the only way to clear his name - and save his skin - is to unmask the real killer. But knowing nothing of the local ways and customs, how is he to even begin? As Jack's attempts to find answers stirs up a hornet's nest of warring factions within the town, events soon start to spiral out of control . . .
