Clare and David Astor are sketching a view of far Spanish hills.

Tom hasn't been told that mum might be leaving him alone with grandma some evenings to go out and see a man called Chris, and that those hills might be the view from his bedroom for years to come.

The hills shimmer off to the left. The sea is mainly out of view to the right as we skirt the untended backs of Carrara and Viareggio.
