I was half way through my MA thesis, or so I thought, when the teacher asked: “Margaret, what is your plumbline?” I had no idea – a) what my plumbline was, or b) what a plumbline was.
I knew I wanted to write about the torn relationship I had with my father who’d died in 1976 in a veterans’ hospital. But what was the narrative arc, apart from a chronological journey to recover our relationship?
What was my plumbline?
One weekend I attended a workshop on ‘Plot’. They explained that plot is different to story. Plot is why something happens. To paraphrase E.M. Forster: story is, “The king died. Then the queen died.” But plot is, ‘The King died. The queen died of a broken heart.” This happened because that happened.
How did plotting help my story?
I ‘d written about seeing “Jack’s Daughters”, a 1980s’ play about five children and their out-of-control ex-POW father. When I revisited this scene I found a plot, or a plot-point. I was not alone in having a serviceman father who suffered PTSD (not called that at the time). As a consequence I was spurred on to find others of my peers who’d had similar child-father relationships.
I could better see my plumbline, or my ‘throughline’ as it is also known. This gave a sense of urgency to my journey of discovery, driving it forward. Or – I’d found just a touch of what Dylan Thomas calls, “The force that through the green fuse drives the flower”. I’d found one small part of the story.

Thanks Margaret for explaining. I’d never heard of a ‘plumbline’ before!

Ha ha. I hadn’t either. It’s what drives the narrative or the TV series, or movie etc.
