Goodreads asked Shane Harrison:

What mystery in your own life could be a plot for a book?

Shane Harrison It’s a scenario that every writer, or would-be writer, must consider. What mystery, or event, in your life could be a plot for a book? Like most writers, I have culled from personal experience. Some do it more than others. There’s always the danger of falling into that less admired genre: a writer writing about a writer writing. But that is just the autobiographical watermark that haunts every page.

Is such writing the equivalent of the self portrait, with the author gazing at their own reflection? Or even a string of reflections stretching back in time. It’s a bit like those infinity mirror set ups. Flann O’Brien’s fictional philosopher, De Selby, proposed that each reflection was like a snapshot in time. He claimed that he could, with a telescope, make out a distant reflection of himself as a child, but couldn’t see further owing to the limitations of the telescope and the curvature of the earth.

I see Sally Rooney, having scored two bestsellers with musings on her own life, writes a third bestseller about a writer who has written two bestsellers. I’m something of the opposite. I may have written two novels but very few have read them. Perhaps that’s the mystery I should write about.

I have been writing non-fiction for most of the last few years. It gives me the chance to complete, or begin the jigsaw, or even glimpse the illustration on the box. But every so often I’m compelled to make something up. Will it be the resolution of some great mystery from my past? Who can tell? I certainly won’t.
