It was an evening late in November. The fog that during the afternoon had been lying like a crouching beast between the closely built houses had now risen. It was as though it had waited till nightfall for its prey, and then departed, leaving a sense of sulkiness in the atmosphere that weighed persistently on the spirits. A slight drizzling rain was wetting the pavements. It clung in a mist to the glass panes of the street lamps, dimming the glow of the light within. In the windows of all the houses the electric lights were burning. You could see clerks, male and female, bent up over their desks beneath them. Some worked steadily, never looking up from their occupations; others gazed with expressionless faces out into the street. Occasionally the figure of a man would move out of the apparent darkness of the room beyond. The light would fan in patches on his face. You could see his lips moving as he spoke to the occupant of the desk; you might even trace the faint animation as it crept into the face of the person thus addressed.
