Woods at the beginning of winter. Cold air. The residue of sunset visible between trees. Lights on in the power station, early night in the medieval quarries. Time in arcs like that, invisible layers of time along the side of the hill, time lacing the branches together, in among the leafmould like a hard frost. Three grey lurchers! Running down the muddy hill! Holly. Your own breath. The sense that you still function. The sense of an ending and of someone keeping pace with you not far off.
