‘Well, I can come every day if you want, Mrs Elm?’

‘Louise, please call me Louise. And don’t you have work to do?’

Nora smiled. Even though it had only been twenty-four hours since she had asked Neil to put up her poster in String Theory, she was already inundated with people wanting lessons. ‘I teach piano lessons. And I help out at the homeless shelter every other Tuesday. But I will always have an hour . . . And to be honest, I have no one to play chess with either.’

A tired smile spread across Mrs Elm’s face. ‘Well, that would be lovely.’ She stared out of the little window in her room and Nora followed her gaze. There was a human and a dog Nora recognised. It was Dylan, walking Sally the bullmastiff. The nervous one with the cigarette burns who had taken a shine to her. She wondered, vaguely, if her landlord would allow her to get a dog. He’d allowed a cat, after all. But she’d have to wait until she’d caught up with the rent.

‘It can be lonely,’ Mrs Elm said. ‘Being here. Just sitting. I felt like the game was up. Like a lonely king on a board. You see, I don’t know how you remember me, but outside of school I wasn’t always the—’ She hesitated. ‘I’ve let people down. I haven’t always been easy. I’ve done things I regret. I was a bad wife. Not always a good mother, either. People have given up a little on me, and I don’t entirely blame them.’

‘Well, you were kind to me, Mrs . . . Louise. When I had a hard time at school, you always knew what to say.’

Mrs Elm steadied her breath. ‘Thank you, Nora.’

‘And you’re not alone on the board now. A pawn has come and joined you.’

‘You were never a pawn.’

She made her move. A bishop sweeping into a strong position. A slight smile tugged at the corners of her mouth.

‘You’re going to win this,’ Nora observed.

Mrs Elm’s eyes sparkled with sudden life. ‘Well, that’s the beauty, isn’t it? You just never know how it ends.’

And Nora smiled as she stared at all the pieces she still had left in play, thinking about her next move.
