The sound of three men clambering over a wall and throwing their ‘looted’ bounty to the ground. A large plastic container of tomato ketchup lies thickly spread across the tarmac, like the scene of violent crime. A short break before the next sonic incursion, a car pulling into a parking space. The reassuring crunch of rubber on grit. The trilogy completed by the thunderous roar of an incoming international flight cutting through the dark air.
