One Sunday recently while staying in London, I took a stroll in the gardens of Temple, the insular clod of quads and offices between the Strand and the Embankment. It's kind of a luxury rent-controlled ghetto for lawyers and barristers, and there is a beautiful tailors, a fine chapel, established by the Knights Templar (from which the compound takes its name), a twee cottage designed by Sir Christopher Wren and a rose garden; which I never promised you.

My mate John and I were wandering there together, he expertly proselytising on the architecture and the history of the place, me pretending to be Rumpole of the Bailey (quietly in my mind), when we spied in the distant garden a hunched and frail figure, in a raincoat, scarf about her head, watering the roses under the breezy supervision of a masticating copper. "What's going on there, mate?" John asked a nearby chippy loading his white van. "Maggie Thatcher," he said. "Comes here every week to water them flowers." The three of us watched as the gentle horticultural ritual was feebly enacted, then regarded the Iron Lady being helped into the back of a car and trundling off. In this moment she inspired only curiosity, a pale phantom, dumbly filling her day. None present eyed her meanly or spoke with vitriol and it wasn't until an hour later that I dreamt up an Ealing comedy-style caper in which two inept crooks kidnap Thatcher from the garden but are unable to cope with the demands of dealing with her, and finally give her back. This reverie only occurred when the car was out of view. In her diminished presence I stared like an amateur astronomer unable to describe my awe at this distant phenomenon.

When I was a kid, Thatcher was the headmistress of our country. Her voice, a bellicose yawn, somehow both boring and boring – I could ignore the content but the intent drilled its way in. She became leader of the Conservatives the year I was born and prime minister when I was four. She remained in power till I was 15. I am, it's safe to say, one of Thatcher's children. How then do I feel on the day of this matriarchal mourning?
