The heroine of A Murdered Peace is a young widow in medieval York whose circumstances are complex enough that readers unfamiliar with the two previous mysteries in this series may find the story hard to follow. To support herself, Kate Clifford runs a guesthouse. She also rents a room by the night to noblemen who need a discreet trysting place with their mistresses. Another of her properties has become a religious house for beguines led by her mother. At home, Kate is responsible for three children who are her wards.
The story begins in the aftermath of the Epiphany Uprising, a rebellion against King Henry IV during the winter of 1399-1400 by men who hoped to restore Richard II to the throne. The rebellion was quickly squashed, its ringleaders beheaded, and Richard imprisoned in Pontefract Castle, where he would die in February 1400.
Kate's cook has disappeared, distressing her and her wards. Then, even more distressingly, an old friend of hers, Lady Margery, arrives seeking a hiding place because her husband has been killed by a mob for taking part in the uprising. If found, Lady Margery too may be killed as a traitor, and Kate may be in danger for sheltering her. The household's peril is deepened when a spice seller in the city is murdered and Kate's cook is accused of the crime.
The complicated backstory does finally become clear enough, even for readers not previously introduced to it, for the tension over the apparently unrelated plights of the cook and Lady Margery to grow absorbing. And what about the attraction between Kate and the knight Sir Elric, who may or may not be trustworthy? Readers who enjoyed the previous Kate Clifford mysteries will want to read A Murdered Peace; those who haven't read them would do better to start at the beginning with The Service of the Dead instead of diving into the series with the third installment.
