Late at night, the city looks different.
Lights flick in and out of focus on the horizon.
Street lamps cast an eerie glow around the silhouette of another person walking in front of you.
There is stillness everywhere, except along the roads where the city moves on.
Reflections, colourful long streaks, plunge into the Thames along the shore.
Faded pale backgrounds blur into spots hanging in the sky like fairy lights.
It is silent but for the distant music, shouts and laughter from a party boat floating by, sinking slowly under the bridge and into the night.
There are no stars in this part of London, but you can at least see the bright moon.
