Prompt
"Create an image of a Cold War-era London cityscape at dusk, with a subtle hint of espionage and secrecy. In the foreground, a vintage telephone and a torn piece of paper with cryptic notes are visible, symbolizing the mole hunt in British intelligence. The style should be reminiscent of a 1970s-era gritty, realistic illustration, with muted colors and bold lines. The image should evoke a sense of tension and paranoia, capturing the essence of John le Carré's classic spy novel, 'Tinker Tailor Soldier Spy'."
