Master Hugh won the Black Prince's favour when he helped to ease the Prince's illness. Now, in the autumn of 1372, the prince is suffering a relapse and sends to Bampton for Master Hugh to attend him. While at dinner in Kennington Palace, Sir Giles, the knight who escorted Hugh to London, is stricken and dies. Poison! Sir Giles is not popular, and there are many who would gladly see the fellow done away with... except for Prince Edward. The Black Prince feels a debt to the slain man because of his heroic behaviour at the Battle of Crecy, where the knight stood firm with the prince when the fight seemed of uncertain outcome. Despite caring little for Sir Giles, Master Hugh must once again place himself in jeopardy and seek to uncover the perpetrator of the crime...

When Bampton's coroner, Hubert Shillside, does not return from a trip to Oxford, Master Hugh de Singleton is called. Concerned for his old friend, Hugh takes to the road to investigate. Travel is safer than in times hence but, out of sight of prying eyes; it is still unwise to travel alone... Hugh finds a body, stabbed and left to rot, but it is not the body he was expecting to find. Indeed, reports of pillage, attacks, and chaos on the roads out of Oxford suddenly seem rampant. Hugh must ascertain whether the incidents are random, or whether something darker is afoot. The guilty cannot afford to be caught, but what lengths will they go to cover their tracks, and will Hugh escape unscathed?

Master Hugh is asked to provide a sleeping potion for Sir Henry Burley, a friend and guest of Lord Gilbert at Bampton Castle. Sir Henry, (with his wife, a daughter by a first wife, two knights, two squires, and assorted servants), has outstayed his welcome at Bampton Castle. The next morning after Master Hugh provides the potion, Sir Henry is found dead, eyes open, in his bed. Master Hugh, the target of the wife's wrath, is asked by Lord Gilbert to determine the cause of death ...

I had never seen Master John Wyclif so afflicted. He was rarely found at such a loss when in disputation with other masters. He told me later, when I had returned them to him, that it was as onerous to plunder a bachelor scholar's books as it would be to steal another man's wife. I had, at the time, no way to assess the accuracy of that opinion, for I had no wife and few books ...' So begins another delightful and intriguing tale from the life of Hugh de Singleton, surgeon in the medieval village of Bampton, near Oxford, and bailiff of Bampton Castle at the behest of Lord Gilbert Talbot. Hugh sets his cap at the delightful Kate, who proves equally resourceful in the search for the missing books. Some very determined adversaries are out to stop him, permanently if necessary - but are they motivated by greed or a more personal animosity? Then the corpse of a poor scholar, who had tried to sell one of the books, is found in the river: but he had not simply drowned ...

Master Hugh, Kate, and their children attend the Midsummer's Eve fire. Next morning early Hugh hears the passing bell ring from the Church of St. Beornwald, and moments later is summoned. Tenants collecting the ashes to spread upon their fields have found burned bones. Master Hugh learns of several men of Bampton and nearby villages who have gone missing recently. Most are soon found, some alive, some dead. Master Hugh eventually learns that the bones are those of a bailiff from a nearby manor. Someone has slain him and placed his body in the fire to destroy evidence of murder. Bailiffs are not popular men; they dictate labour service, collect rents, and enforce other obligations. Has this bailiff died at the hand of some angry tenant? Hugh soon discovers this is not the case. There is quite another reason for murder ...
