An Antidote for Avarice — Caroline Roe

In medieval Spain, the blind Jewish physician Isaac of Girona is revered for his skill as a healer. But it's Isaac's uncanny sense for what is flair and what is foul that proves to be the remedy in times of trouble...

Girona, Spain, 1354. His Excellency the Bishop Berenguer has been summoned to Tarragona to attend a Bishop's Council. Complaining of illness and out of favor with both the King of Aragon and the Archbishop of Tarragona, His Excellency is reluctant to make the journey and insists his personal physician accompany him. Isaac also dreads the long trip since his wife is along to try a bit of matchmaking for his most reluctant daughter. But their troubles have only just begun. Messengers from the Pope keep turning up dead--and Isaac finds himself embroiled in court intrigue and murder on the road to Tarragona.
