I crack one eye open and roll quickly to the side of the bed.

“Ben. Never. Ever. Get in my face in the morning, especially when I’m supposed to be seeing Susan there …”

“Sorry, you were moaning. Blimey you look bad.” ( Ben’s one of those annoying people who can get up in the morning ready to go. )

I hold my wand ahead of me, ducking low to go through yet another support beam opening. I can’t believe this was all made by Muggles. Well, to be fair, it wasn’t entirely Muggle-made. I mean if it had been, it would never have survived the Blitz. Sure, the major grunt-work was done by Muggles; toting cart after cart of yellow bricks, mole-like, into the dark chasms of the earth on some crazy roller coaster-like contraption, mortaring them together while fighting off the ever-present fear of cave-ins. But oddly enough, it was Gellert Grindelwald who cast the Support Charms on the tunnels during World War Two. Otherwise, London would have been a much different city.

( Now of course, don’t get me wrong. )
