He crosses the front room, which he calls his study, and comes down the staircase. The stairs turn a corner; they are narrow and steep.

Comparing the two cities — the Berlin I knew in the early thirties and the Berlin I revisited in the early fifties — I have to admit that the latter is, in many respects, a far more exciting setting for a novel or a sequence of stories. Life in the Berlin of 1952 had an intensely dramatic doubleness. Here was a shadow-line cutting a city in half — a frontier between two worlds at war — across which people were actually being kidnapped, to disappear into prisons or graves. And yet this shadow-frontier was being freely crossed in the most humdrum manner every day, on foot, in buses, or in electric trains, by thousands of Berliners commuting back and forth between their work and their homes. Many men and women who lived in West Berlin were on the black list of the East German police; and, if the Russians had suddenly marched in, they couldn’t have hoped to escape. Yet, in this no man’s land between the worlds, you heard the usual talk about business and sport, the new car, the new apartment, the new lover.
