Ruth is now driving between overhanging trees, the verges rich with cow parsley. In a moment, she knows, the trees will vanish as if by magic and the sea will be in front of her. She never tires of this moment, when the horizon suddenly stretches away into infinity, blue turning to white turning to gold. She drives faster and, when she reaches the caravan site that marks the start of her road home, she stops and gets out of the car, letting the sea breeze blow back her hair.

Ahead of her are the sand dunes, blown into fantastic shapes by the wind. The tide is out and the sea is barely visible, a line of blue against the grey sand. Seagulls call high above and the red sail of a windsurfer shimmers silently past.

Without warning, Ruth leans over and is violently sick.

Norwich Castle, a Victorian icing covering a rich medieval cake, is now a museum. Nelson has been there several times with his daughters. They used to love the dungeons, he remembers, and Laura had a soft spot for the teapot collection. He hasn’t been for years though and as he and his wife Michelle ascend the winding pathway, floodlit and decorated with heraldic banners, he fears the worst. His fears are justified when they are met by serving wenches. The invitation did not mention fancy dress but these girls are very definitely wenches, wearing low-cut, vaguely medieval dresses and sporting frilly caps on their heads. They are proffering trays of champagne and Nelson takes the fullest glass, a fact not wasted on Michelle.

‘Trust you to take the biggest,’ she says, accepting a glass of orange juice.
