When Charles Dickens wrote the opening of A Tale of Two Cities, he could have been talking about London during one week in July 2005.
On Saturday, 2 July London hosted the Live 8 concert and a few days later on Wednesday, 6 July, the capital was declared the host city for the 2012 Olympic Games.
With world leaders gathering for a crucial G8 Summit in Scotland, the eyes of the world seemed to be on Britain and on London.
This is why many Londoners would have woken up on the morning of July 7, 2005 with a real sense of optimism.
It was the height of summer and Britain was at the epicentre of a global campaign to eradicate poverty; the successful Olympic bid would bring with it regeneration, jobs and prestige.
Then, in a terrifying hour towards the end of the morning commute, all those dreams of a better world were suddenly replaced by an incendiary nightmare.
