daughter inching over the top of the stairs, pulling electrical leads that were about to bring the kettle or iron down on top of her, delving into the rubbish. She husked records from their sleeves and shredded letters in their envelopes with the speed of a harvesting peasant. She aimed herself at bottles of bleach or hot cups of tea, trundling across rooms like a slow but deadly missile and changing course only if someone actually went and stood between her and her target. Suddenly our life was like a drama in which a bomb is being disabled against the clock.
