The Poisoned Chalice — Bernard Knight

December, 1194. The well-born ladies of Exeter are not having a good week. First, Christina Rifford, the daughter of a rich merchant, is raped. Then, just months before her marriage, Lady Adele de Courcy is found dead in one of the poorest areas of the city.

The common factor is Godfrey Fitzosbern, the local silversmith. But despite Crowner John's suspicions and the vengeful accusations of the families of the two women, it is John's duty to protect Godfrey until he can find definite proof of his guilt.

Aided by his mistress, Nesta, and hindered by his social-climbing wife, Matilda, and her power-hungry brother, Sheriff Richard de Revelle, John slowly begins to put the pieces together.

Then a final, brutal act of violence brings a new twist to the investigation .. .
