I arrived at the house, after walking through those silent and deserted streets, in which the few who stood seemed occupied on some dark official business, and in which party slogans and symbols disfigured every building. The staircase of the apartment building was also deserted. Everywhere the same expectant silence hung in the air, as when an air raid has been announced, and the town hides from its imminent destruction. Outside the apartment, however, I encountered two policemen, who seized me as I rang the bell and demanded my papers. Dr Tomin came out, and an altercation ensued, during which I was pushed down the stairs. But the argument continued and I was able to push my way up again, past the guards and into the apartment. I found a room full of people, and the same expectant silence. I realized that there really was going to be an air raid, and that the air raid was me. In that room was a battered remnant of Prague's intelligentsia - old professors in their shabby waistcoats; long-haired poets; fresh-faced students who had been denied admission to university for their parents' political 'crimes'; priests and religious in plain clothes; novelists and theologians; a would-be rabbi; and even a psychoanalyst. And in all of them I saw the same marks of suffering, tempered by hope; and the same eager desire for the sign that someone cared enough to help them. They all belonged, I discovered, to the same profession: that of stoker. Some stoked boilers in hospitals; others in apartment blocks; one stoked at a railway station, another in a school. Some stoked where there were no boilers to stoke, and these imaginary boilers came to be, for me, a fitting symbol of the communist economy.
