It struck him that the man’s whole life was playing a part, and that he felt it to be dangerous to drop his assumed personality even for a moment. O’Brien took the decanter by the neck and filled up the glasses with a dark-red liquid. It aroused in Winston dim memories of something seen long ago on a wall or a hoarding—a vast bottle composed of electric lights which seemed to move up and down and pour its contents into a glass. Seen from the top the stuff looked almost black, but in the decanter it gleamed like a ruby. It had a sour-sweet smell. He saw Julia pick up her glass and sniff at it with frank curiosity.
