The rule of the Plantagenets saw an unbroken line of fourteen kings reign over 300 years, but while these kings are undeniably interesting, often it is their wives, the queens of the medieval period who command the attention, I'm talking of histories she wolves, Eleanor of Aquitaine, Isabella of France and Margaret of Anjou, and as such, I am thrilled to welcome back the woman who wrote the book and fronted the series dedicated to histories she wolves, Dr Helen Castor, who joins me to discuss these three remarkable queens.
