Toby had hardly broken a sweat by the time he reached the end of the first part of the challenge and grabbed hold of the crenelated wall at the top of the figures. He slipped through the gap in the wall and turned around, making sure the GoPro on his chest was pointing forwards. He leaned over and waved at his own phone. He didn’t want to waste any more time and so he turned back around and looked up at the rose window.

The rose window itself was the easiest part to climb; it was practically a ladder once you got past the long slim windows into the actual rose. He got to the top of the structure in no time. He made sure to look down, so that he could get a shot of the ornate window directly beneath him with the camera strapped to his head. He wondered how many viewers he had now. No sirens yet.

At the top of the window he had a couple of tricky manoeuvres to do before he could get over the second ledge onto the small balcony. Once they had been executed, he grabbed the thin ledge and pulled himself up, and then hoisted himself over the wall. One last push before he could get onto the roof. He could go to the side and climb up that way, but it wasn’t as interesting for his followers and so he continued on his path straight upwards. He was feeling a little tired – probably the cider; next time one can would be enough. He didn’t know why he had been so nervous in the first place; this was a doddle.

He climbed up the final window and grabbed hold of the feet of the statue standing at the top of it. He didn’t know who it was of, probably St Peter. Neither history nor religious studies were his subjects at school, so he hadn’t paid attention on the various school trips they had made to the building over the years.

He got his hand around the spike at the centre of the top of the roof and pulled himself up. He didn’t give himself time to rest; he wanted his followers to see the view and so he spun around and looked out over the city. His phone was a tiny blip on the ground from where he was standing, but he waved nonetheless. He would splice the footage together later and put it to music. This was going to look awesome; he couldn’t wait to watch it back.

He looked behind him at the lopsided crossed roof and then to the North Tower. He had to go up there; it was the highest point after all. The roof was battered and difficult to navigate, the central beam covered in an ornate metal design, presumably specifically to stop these kinds of shenanigans. From the centre of the roof he couldn’t see his phone any more, but he wasn’t particularly worried about anyone stealing it. He made his way across the central beam towards the North Tower and started to climb.
