Cavendish Flint is a Bulldog, stubborn in public and soft hearted in private, a proper comic boulder. There is a story going around that Cavendish Flint once heard a pair of goggles claiming to see another layer of reality answer back, briefly. Pups recognise Cavendish Flint from the back, which is a compliment in The Yard whether or not it sounds like one. Cavendish Flint chases the kind of small purpose that fits in a coat pocket and refuses to leave.
