I have just finished reading Excalibur the third book in your Arthur trilogy. The narrator for all three books was Derfel and when Arthur set sail to Brittany Derfel states that Arthur was never heard of again. Okay but what about Derfel and Ceinwyn? How did Derfel end up in a monastery? I know he was oathed to the bishop, the mouse lord. And Igraine what of her? Is there another book with Derfel?  I so enjoyed the Atrhur books and of course the Saxon Tales with Uhtred.
