It is pitch black by the time Ruth drives home, edging her car carefully along New Road. There are ditches on both sides of the road and the merest twitch on the wheel can send you plunging ignominiously downwards. This has happened to Ruth once before and she is not keen to repeat the experience.

Her headlights illuminate the raised tarmac of the road; the land drops away on either side so that she seems to be driving into nothingness. Nothing but the road ahead and the sky above. Where the earth meets the sky. She shivers and turns on the car radio. Radio 4, soothing, civilised and slightly smug, fills the car. 'And now for the News Quiz…'

Ruth parks outside her broken blue fence and pulls her rucksack out of the boot. The weekenders' house is in darkness but the warden has a light on upstairs. She assumes he goes to bed early so as to be up for the dawn chorus. Flint appears on her doorstep mewing piteously for admittance even though he has his own cat-flap and has, in fact, been snoozing inside all day. Remembering she hasn't yet seen Sparky, Ruth feels a pang of anxiety as she opens the door. But Sparky, a small black cat with a white nose, is sleeping safely on the sofa. Ruth calls her but she stays put, flexing her claws and shutting her eyes. Sparky is a reserved character, quite unlike Flint who is now weaving ecstatically around Ruth's legs.

'Stop it, you stupid cat.'

She drops her rucksack on the table and puts down food for the cats. Her answer phone light is flashing. She has a feeling that it won't be good news and when she presses PLAY she is right. Her mother's voice, aggrieved and slightly breathless, fills the room.

'… whether you're coming for Christmas. Really, Ruth, you could be a bit more considerate. I heard from Simon weeks ago. I assume you'll be coming because I can't imagine you'll want to spend Christmas on your own in that awful…'
