This mediaeval murder mystery is set amongst the dramatic and stormy mountain landscapes of the Pyrénées and the ancient territory of Aragón. Meticulously researched - including maps - with rich detail of the setting and society, and the lyrics of the era, illustrating a satisfying tale that is full of twists and turns. There is even a trial by combat. The series will appeal to fans of Brother Cadfael, but Beatriz the protagonist is a young female troubadour (trobairitz) in the service of Philippa of Tolosa (Toulouse), a noblewoman about to enter an arranged marriage. In a world where women lack agency, the author has succeeded in giving our heroine a skilful and intelligent, yet convincing role. I was immersed in this novel and read eagerly to the conclusion.

‘As the drawbridge came down and I ventured in, I was not disappointed. I remember nothing of what happened in my everyday life until I came out at the end.’

‘Human chess played with lives and land.’
