So I had to go to Zurich again for a few days. My mother wished to see me. And because of my nerves about it, I’d felt so unwell over the whole long weekend that I suffered from severe constipation. On top of this, I should say that I’d written a novel a quarter century ago which I’d titled, for some reason I regrettably no longer recall, Faserland. It ends in Zurich, out in the middle of the lake, so to speak, somewhat traumatically.

That chapter of my life came back to me for the first time in years when, in Zurich as I said, down on Bahnhofstrasse, I purchased a dark brown, rather chunky wool sweater at a little stall hammered together from wooden beams, not far from Paradeplatz. It was already evening, I’d taken some valerian, and the effect of the pills and the despair of the Swiss autumn and the twenty-five preceding years weighed, leaden beyond measure, on my mood.
