I ram the dishcloth in the overflowing bin and look under the sink for a new one. There is no new one. Of course, there is no new one, Kate, you haven't been here to buy a new one. Retrieve old dishcloth from the bin and soak it in hot water with a dot of bleach. All I need to do now is put Emily's wings and halo out for the morning.

Have just turned off the lights and am starting up the stairs when I have a bad thought. If Paula sees the Sainsbury's cartons in the bin, she will spread news of my Great Mince Pie forgery on the nanny grapevine. Oh, hell. Retrieving the cartons from the bin, I wrap them inside yesterday's paper and carry the bundle at arm's length out through the front door. Looking right and left to make sure I am unobserved, I slip them into the big black sack in front of the house. Finally, with the evidence of my guilt disposed of, I follow my husband up to bed.

Through the landing window and the December fog, a crescent moon is reclining in its deck chair over London. Even the moon gets to put its feet up once a month. Man in the Moon, of course. If it was a Woman in the Moon, she'd never sit down. Well, would she?

I take my time brushing my teeth. A count of twenty for each molar. If I stay in the bathroom long enough, Richard will fall asleep and will not try to have sex with me. If we don't have sex, I can skip a shower in the morning. If I skip the shower, I will have time to start on the e-mails that have built up while I've been away and maybe even get some presents bought on the way to work. Only ten shopping days to Christmas, and I am in possession of precisely nine gifts, which leaves twelve to get plus stocking fillers for the children. And still no delivery from KwikToy, the rapid on-line present service.

"Kate, are you coming to bed?" Rich calls from the bedroom.

His voice sounds slurry with sleep. Good.

"I have something I need to talk to you about. Kate?"

"In a minute," I say. "Just going up to make sure they're OK."

I climb the flight of stairs to the next landing. The carpet is so badly frayed up here that the lip of each step looks like the dead grass you find under a marquee five days after a wedding. Someone's going to have an accident one of these days. At the top, I catch my breath and silently curse these tall thin London houses. Standing in the stillness outside the children's doors, I can hear their different styles of sleeping--his piglet snufflings, her princess sighs.

When I can't sleep and, believe me, I would dream of sleep if my mind weren't too full of other stuff for dreams, I like to creep into Ben's room and sit on the blue chair and just watch him. My baby looks as though he has hurled himself at unconsciousness, like a very small man trying to leap aboard an accelerating bus. Tonight, he's sprawled the length of the cot on his front, arms extended, tiny fingers curled round an invisible pole. Nestled to his cheek is the disgusting kangaroo that he worships--a shelf full of the finest stuffed animals an anxious parent can buy, and what does he choose to love? A cross-eyed marsupial from Woolworth's remainder bin. Ben can't tell us when he's tired yet, so he simply says Roo instead. He can't sleep without Roo because Roo to him means sleep.

It's the first time I've seen my son in four days. Four days, three nights. First there was the trip to Stockholm to spend some face time with a jumpy new client, then Rod Task called from the office and told me to get my ass over to New York and hold the hand of an old client who needed reassuring that the new client wasn't taking up too much of my time.

Benjamin never holds my absences against me. Too little still. He always greets me with helpless delight like a fan windmilling arms at a Hollywood premiere. Not his sister, though. Emily is five years old and full of jealous wisdom. Mummy's return is always the cue for an intricate sequence of snubs and punishments.
