The initial inspiration for Roman Bridge was the fact that rural Scotland is peppered with old stone bridges. Loads are called the Roman bridge but not many of them are. I like that, things seeming to be one thing and turning out to be something else. And I was trying to find a place to set a whole play in real time. An old bridge has lots going for it. Bridges are a place between places and are loaded with meaning and potential threat.

The writing attachment with NTS was a godsend. I was able to take long walks in the snow and empty my head of the bits and bobs of everyday nonsense. I got up really early and wrote in the dark and went out for a couple of hours at first light; trudging through the white trees around the frozen Clyde put the characters and the things they endure into a solid perspective. The end was never satisfying enough before the attachment – I think it is now. I hope the audience agrees!

Are their plans to mount a full production? I hope so. That’s for NTS to decide. The more people that make the effort to see the play will probably help to influence that decision …

I’ve always got ideas for a new play. I’m thinking about one that revolves around a planned bare-knuckle fight. A big cast. It might be called Square Go. But the funny thing is plays evolve as they are developed so it might end up being a monologue about cross-stitch and puff pastry.
