The television cameras switched quickly between scenes. Three minutes silence in the House of Commons, three minutes silence in Parliament Square, three minutes silence at the BBC. MP's, pedestrians and television staff, stood shock still in remembrance.

Then the picture flicked to the London Stock Exchange. Closest to the camera, a trader, standing like the others but with his head cocked at an odd angle. Remembering the dead? Praying for bereaved families? No. His head was skewed towards a computer monitor, his eyes fixed on the flickering financial information. Keen not to lose a single dollar for the dead.
