A Potion for a Widow — 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 fair and what is foul that proves to be the remedy in times of trouble...

In 1354, Isaac's young protege, Yusuf, is about to leave for Sardinia, where uprisings against the King are at the boiling point. But then, the mild-mannered clerk Pasqual Robert falls victim to an attacker outside the gates of Girona. And with the deadly blade still lodged in Pasqual's back, all Isaac can do is make his passing as comfortable as possible. . .and bring his assassin to light.

Once Yusuf is on his way to join the King's court, Isaac is left to track down a killer. Upon further inspection, it appears Pasqual had good reason to keep so quiet--and with a past like his, good reason to look over his shoulder from time to time. Now, even with the help of His Excellency, Bishop Berenguer, it will take all of Isaac's wit--and his ability to see beyond the surface--if the truth is ever to be found...
