Isaac sends Yusuf off with a band of men going to join the king, led by Oliver de Centelles, who promises to keep Yusuf safe. While the band is traveling, they come across a young waif, who claims to be a young boy, but they later discover is a young girl, and a young girl of good breeding, they later learn. She claims her family is dead and has no knowledge of where any relatives may be. Oliver is quite taken with her and becomes determined to help her locate her family.

Back in Barcelona, Isaac and his daughter Raquel encounter a man near death on the back of his horse as they see Yusuf and his band off. The man is not from around there and appears to be quite acquainted with Oliver, though he dies before Isaac or the Bishop are able to ascertain his true identity and who might have killed him. Among his papers, Isaac discovers heartfelt letters written by a woman who certainly must be the man's wife.

While it looks as though they may never learn who killed the man and why, Isaac feels bound to attempt to locate the woman who wrote these letters. Little does he imagine that his search will cross with Oliver and his band and will lead them into mortal danger as they uncover not only the murderer, but an evil man whose hatred and greed has been harboring many years, waiting to be unleashed.

A Potion for a Widow continues a strong series set in fourteenth century Spain. In this episode, Isaac does not play as major a role as he normally does, letting Yusuf and his new companions carry the story. An admirable character to take Isaac's place as a main character, Oliver is very likable, tough with his men when necessary, yet he has a good deal of compassion that he is not afraid to show. Yusuf has learned well at Isaac's feet and is growing into a strong young man. Isaac's daughter continues to play a strong supporting role as her father's companion and is beginning to take steps to independence as she pines for her Daniel who is a sea and scheduled to be back before the high holy days.

The setting and atmosphere are both exceedingly authentic, yet not so overwhelming as to lose the interest of those not well acquainted with the era. The mystery, not terribly difficult to solve, takes a back seat to the several love stories unfolding. The subplot is very enchanting as long lost loves, including families, are reunited and new loves and bonds are forged. The young characters take center stage and carry off their stories very well.
