Sorry, I don't understand the first answer. I have Waugh as the novelist in Clue 3 and AE Coppard goes with Hips and Haws. The Golden Cockerel is a publisher. Where did it originate (village in Oxfordshire).
Just got the answer. Look at the battle that took place in 1469. Travel ESE of here to a 16th century building and google this place to reveal the answer.
