A Bloody Field by Shrewsbury

From Edith Pargeter, who also wrote as Ellis Peters, A BLOODY FIELD BY SHREWSBURY is a vivid medieval tale of Henry IV's kingdom in crisis. 'Chivalry, treachery, conflict of loyalties... The clash of wills is as stirring as the clash of steel' Observer It is 1399. Henry Bolingbroke, unjustly banished and deprived of his inheritance by Richard II, returns to claim his rights and deposes the king to become Henry IV of England. He is aided by the powerful lords of Northumberland, especially by his friend, Harry Percy, nicknamed Hotspur. But the triumph of his accession quickly turns sour in the face of ever-growing crises in his new kingdom, and Wales is the most pressing and troublesome of these. For although Henry's son and heir, Prince Hal, is the nominal Prince of Wales, the Welsh have a prince of their own blood in Owen Glendower, and they are swift to rally to his rebellious call to arms. The three Henries all wish to see the House of Lancaster succeed, but their partnership contains the seeds of its own destruction. The memory of past crimes and growing doubts and divisions cause a dangerous rift. The king also has powerful enemies who are all too willing to take advantage of this and tension mounts as the three men are drawn inexplicably to a bloody collision some two miles from Shrewsbury...
