Liverpool Street at night is a darkling place; it darkles. Out of the dimness the red and yellow illuminated signs of the JAZZ BUFFET AND BAR, of CIGARETTES AND SWEETS assert themselves. In the dimness and against the fluorescent lights over the ticket barriers travellers manifest themselves halfway between chiaroscuro and silhouette. There is a general echoing of rattling and rumbling, there is a dark and stertorous clamour. The Harwich train will leave at 19.40 from Platform 9.
