M le Maire's favourite Queen, Eleanor of Aquitaine has been having her story told on 4 Extra lately.
Three series of Eleanor Rising by Shaun McKenna are available on BBC Sounds. I'm working through series one at the moment.
Rose Basista plays E of A. I've not heard of her before but will look out for her in the future and Joel McCormack,who was in Wolf Hall and I'm sure loads of radio stuffs, as I recognise his voice*, as The Dauphin/Louis VII. Stalwart of Radio 4 drama, Carl Prekopp is the not-to-be-trusted Abbot Pruger.
*Just worked it out. He was in Home Front (an intermittent serial drama about the First World War), playing Victor Lumley.
