It was a bright cold day in April, and the clocks were striking thirteen.
|
|
Winston Smith, his chin nuzzled into his breast in an effort to escape the
|
|
vile wind, slipped quickly through the glass doors of Victory Mansions,
|
|
though not quickly enough to prevent a swirl of gritty dust from entering
|
|
along with him.
|
|
|
|
The hallway smelt of boiled cabbage and old rag mats. At one end of it a
|
|
coloured poster, too large for indoor display, had been tacked to the wall.
|
|
It depicted simply an enormous face, more than a metre wide: the face of a
|
|
man of about forty-five, with a heavy black moustache and ruggedly handsome
|
|
features. Winston made for the stairs. It was no use trying the lift. Even at
|
|
the best of times it was seldom working, and at present the electric current
|
|
was cut off during daylight hours. It was part of the economy drive in
|
|
preparation for Hate Week. The flat was seven flights up, and Winston, who
|
|
was thirty-nine and had a varicose ulcer above his right ankle, went slowly,
|
|
resting several times on the way. On each landing, opposite the lift-shaft,
|
|
the poster with the enormous face gazed from the wall. It was one of those
|
|
pictures which are so contrived that the eyes follow you about when you move.
|
|
BIG BROTHER IS WATCHING YOU, the caption beneath it ran.
