My BBC Radio 4 play is dead. Not my fault, not the BBC’s fault, and I can’t ever tell you why. It’s dead and by chance it died on precisely the 1,000th day since I began researching it.

There is no upside, there is no bright side. It is devastating to me and I see no chance of anything positive coming from the situation.

The same reasons that mean I can’t tell you why mean I also can’t ever explain this: it was the best thing I have written to date. Writers are supposed to dig deep and I went archaeological on this one, but I also had to go sideways. Nothing, not one single thing, about this play is remotely like anything I’ve written or tried to write before.

I mean the bones of it, the structure. I wouldn’t have even guessed that you could tell a story in this way, which is very likely a failure of my imagination. The story dictated it, the story drove it in this direction and in this form. I’m minded of Gromit laying track as the train races on, and so many times it all felt as frantic as that.

There were mornings when I’d wake up either sweating or shaking because the play was in me and it was that important. The chief reason I wrote it was to see whether it was physically possible to write it, and whether I was capable of doing it.

It was and I was, and I am proud of it. I’m conscious that my pride is just rather pointless.

I’ve said and thought before that nothing you write is wasted. That idea is being rather tested now, but still I do see that I’m a better writer for having written this. That isn’t enough. But it’s something.
