Idle speculation, of course, but occasionally I’ve fantasized that the great historian Richard Cobb and I chanced to be sitting together on a tram in Toulouse in 1946, when I was 4 and he was in his late twenties and just about to be demobbed. He’d have been on his way to visit a young woman he’d met at the British Fortnight organized in the city by the British Council. I’d have been riding the tram for the thrill of it, in the care of its conductress, who was a lodger in my maternal grandparents’ boarding-house behind Place du Capitole, as were my mother, sister, newly born brother and I, dispatched from England for a few months while my father, no longer able to support us properly, looked for a permanent teaching post.
