Sir John de Reville
He is the king’s Coroner, Crowner Jack or “Black” Jack as he is known is seen, at best, as a questionable figure in the neighbourhood. Only rousing himself out of Exeter when there is an “un-natural” death in the neighbourhood, most view him as a bit ghoulish.
In actuality, he is that rarest of rare, an honest and intelligent bureaucrat attempting to perform his unpleasant task with limited resources.
He, Sir John Corbett, and Aelred, are old military comrades.
