The kitchen barely has room for a fridge and a cooker but Ruth, despite the books, rarely cooks. Now she switches on the kettle and puts bread into the toaster, clicking on Radio 4 with a practised hand. Then she collects her lecture notes and sits at the table by the front window. Her favourite place. Beyond her front garden with its windblown grass and broken blue fence there is nothingness. Just miles and miles of marshland, spotted with stunted gorse bushes and criss-crossed with small, treacherous streams. Sometimes, at this time of year, you see great flocks of wild geese wheeling across the sky, their feathers turning pink in the rays of the rising sun.

But today, on this grey winter morning, there is not a living creature as far as the eye can see. Everything is pale and washed out, grey-green merging to grey-white as the marsh meets the sky. Far off is the sea, a line of darker grey, seagulls riding in on the waves. It is utterly desolate and Ruth has absolutely no idea why she loves it so much.

She eats her toast and drinks her tea (she prefers coffee but is saving herself for a proper espresso at the university).

As she does so, she leafs through her lecture notes, originally typewritten but now scribbled over with a palimpsest of additional notes in different coloured pens. 'Gender and Prehistoric Technology', 'Excavating Artefacts', 'Life and Death in the Mesolithic', 'The Role of Animal Bone in Excavations'. Although it is only early November, the Christmas term will soon be over and this will be her last week of lectures. Briefly, she conjures up the faces of her students: earnest, hard-working, slightly dull. She only teaches postgraduates these days and rather misses the casual, hungover good humour of the undergraduates. Her students are so keen, waylaying her after lectures to talk about Lindow Man and Boxgrove Man and whether women really would have played a significant role in prehistoric society. Look around you, she wants to shout, we don't always play a significant role in this society. Why do you think a gang of grunting hunter-gatherers would have been any more enlightened than we?
