Blogger speaks about reaching summit of Shard

It took a few minutes of lingering before the walkway was clear of people - we grabbed onto the scaffolding pipes and swung off the bridge.

Hanging on the freezing pipes, we pulled ourselves on top of the walkway and laid down out of view, waiting for a reaction in case anyone had seen or heard us. It didn't seem so.

Staying low, we then descended the other side of the scaffolding, right behind the security hut where we could see the guard watching TV, not the cameras.

Quickly, we scampered across the yard and found the central stair case, again pausing to see if there was any reaction from the yard, phones ringing or doors opening. It was silent.

We were so high, I couldn't see anything moving at street level. No buses, no cars, just rows of lights and train lines that looked like converging river systems, a giant urban circuit board.
