Rob and Bellamy pick up a man claiming to be a local farmer who presumably perished in a London air raid in the 1940s. As no body was ever found, he claims to have lost his memory and soon causes a stir when he tries to pick up where he left off with his wife, who has remarried and is now trapped in a loveless marriage with a seriously-ill abusive man, who seems to know more about the circumstances behind his rival's disappearance than he is letting on. Meanwhile, Lord Ashfordly's behaviour takes a strange turn after he eats some of Peggy's peculiar batch of mushrooms, whilst Younger asks Rosie for driving lesson when Miller books him on an official police driving course, but she is horrified when their "romance" comes the talk of the village.
