I would classify this series as a Medieval murder mystery/historical fiction. The story takes place in the early 1300's in the moors near Devon, England. The book is slow and rambles at times, but also provides a look into medieval history, the stannaries or tin camps, and the legal system that prevailed. There are vivid descriptions of the people, their culture, food, drink, the moors, class distinctions, attitudes, etc. One of the main characters is the moors themselves. There are a plethora of suspects that need to be questioned about their alibis. What prevented me from giving four stars is that the only avenue to finding the murderer is by interrogating everyone; and in doing so, clues or unanswered questions are raised and our sleuths continually need to revisit a suspect to do more questioning. There are also lots of repetition of speculation on who and how the murder happened as well as many descriptions of facial expressions and demeaners. This slows down the story and is redundant.
Some history to understand the story: A king needs money to rule. One way to get it is to own all the tin mining land on the moors and tax the miners. But the king also gave the miners extensive privileges and benefits in mining his tin. Some of the privileges included digging anywhere even on other landowners property, they could divert rivers and streams when needed, having their own laws and parliament, and villeins or serfs could run away from their masters and flee to the moors where they set themselves up as tin miners and then were under the king's protection. Thus the landowner had no legal claim on the return of his villein. If not for the legality, the villein would be brutally punished when caught.
Our intrepid sleuthing duo is Simon Puttock, the bailiff of Lydford Castle and his tag-along partner Sir Baldwin Furnshill, the Master of Furnshill Manor and a former Knight Templar. They make a good crime solving team because Simon is good at interrogating suspects and Baldwin is good at reading clues. They are summoned to the moors by Sir William Beauscyr to adjudicate a situation involving Beauscyr's villein, Peter Bruther, who has run away and become a miner which makes him instantly free. Simon tries to convince Sir William that there is nothing he can do because Peter Bruther is now under the protection of the king. There has been a history of clashes between the "tinners" and the other landowners and Sir William is not convinced that he has no legal claim to his villein.
Later, Peter Bruther is found hanged in Wistman's Wood. Baldwin deduces that Bruther was strangled somewhere else and transported and hung from a tree in the woods - that's cold-blooded murder! Simon and Baldwin must return to the moors and unravel the truth before violence erupts between the miners and the landowners. Then, when they are at a stand still in the investigation; the two men at arms, Samuel Hankyn and Ronald Taverner, who discovered the body of Bruther are also murdered under cover of a attention distracting fire started in Sir William's barns. Why? Our duo continue questioning and seek out discrepancies, falsehoods, observations and by intuition and "ah-ha" moments are lead to the truth and the murderer. In the meantime Sir Robert Beauscyr is kidnapped by the miners because the mine leader thinks he is the murderer of Bruther, tempers flair, and a small battle ensues to get him back. Why is Thomas Smyth, the wealthy tinner, so bent on getting justice for Bruther's murder?
Suspects include: Sir William Beauscyr who is humiliated by the loss of his villein; his bickering sons, Sir Robert who will inherit the estate and visiting John Beauscyr, a knight in training accompanied by his master, Sir Ralph of Warton; Thomas Smyth, the leader of the miners who also runs a protection racket on the side that, if funded, will prevent his men from coming on a landowners property and mining for tin thus destroying the land; Adam Coyt, a nearby landowner who dislikes miners, etc.
There were several twists and turns in the some-what convoluted but well written plot. There is lots of interesting history. I also like the amusing exchanges and personal conversations between Simon and Baldwin. A recommended series.
