I understood and twisted his warm fingers into mine. After five months of marriage I could recognize the ridges and wrinkles in his skin. ‘At least we’re on the same side of it.’

‘Yes. That’s something.’ He sighed. ‘I do have friends over there, though.’

I looked over at the guards, wondering what they were thinking as they stared back at us. It must all have seemed very different to them. Perspective changes things. ‘I expect you’ll see them again. They might be on the other side right now, looking this way.’

‘Perhaps.’

A man approached the schoolboys, offering photographs of the Wall to be used as postcards. ‘Strange things to send,’ I said.

‘Presumably you give them to people you don’t like.’ I smiled.

The school party stopped in front of a hoarding showing the country split in half, with ten occupied babies’ cots on the other side, and nine on ours alongside an empty one bearing the slogan YOUR CHILD. STRENGTH IN NUMBERS! The boys’ teacher reached into his briefcase, took out another copy of the red book, in which the First Secretary had set out our nation’s course, and began to read out a passage.

Nick nodded in his direction with a sceptical smirk. ‘Does he think it’s all going to work so beautifully?’ he said.

I glanced around to make sure we couldn’t be overheard. ‘Well it’s worth trying, isn’t it? Surely if the state makes certain everyone is fed and has a job, nine tenths of all the fights and arguments we have with each other will be gone.’ And really it did make sense – God knows there were difficult aspects to our new life, but the argument seemed entirely logical, and rehearsing it in my mind made me hopeful for the future.

‘Overnight. In a puff of smoke.’ He tried to suppress a smile.

‘Oh, you’re a horrid man.’ I poked him in the ribs. ‘So what’s your big idea, then?’

‘I’m glad you asked,’ he said. ‘A gliding wing.’

‘A gliding wing?’

‘That’s it. We build it on the roof in the dead of night, wait until the wind picks up, then soar over the Wall like a couple of birds. Down a pink gin and slip into the best hotel we can find for an hour.’ He did some calculations in his head. ‘Make it ninety minutes.’

‘You need a cold shower.’ But my hand slipped around his waist.

‘Maybe I do.’ A soldier crossed from one side of the watch tower to the other, scanning the crowd with his binoculars. ‘Awful job,’ Nick said.

‘People surprise you. What they can do.’

‘That’s true. That’s always true.’ Above us a flock of black birds drifted so high that they became specks of dust. ‘Shall we go?’

I nodded. ‘Yes, let’s.’
