Mr. Cornwell, I know that Ivar the boneless was a real and successful viking leader, and one story I have heard about him was that he suffered some sort of disability were he was unable to walk on his own and had to be carried around on an upturned war shield. I was wondering if you used this in any way when you were describing his son Ivar Ivarson”s condition when Uhtred and King Guthred first met him after his defeat at the hands of the Scots in your novel Lords of the North? humbly, Jared Hess
