Big Ben – 1000 Piece Jigsaw Puzzle (Eurographics)

The light is going over Westminster and the sky behind the tower has turned pink and gold under the grey. Big Ben's clock face is already lit, the Houses of Parliament are washed in warm floodlight along the water, and the lamps have come on all the way across the bridge.

Stand on the far bank at this hour and the Thames goes quiet and silver while the city carries on above it!
