Sometime in the late 1990s, when I was staying in Dublin with my sister Marie Heaney and her husband Seamus, he was working on the introduction to a book called A Way of Life, Like Any Other, which I took to be a novel. I’d never heard of it, but the fact that Seamus was writing an introduction to this new edition seemed like an honour and signalled importance. First published in 1977, it had won both the Guardian Fiction Prize and the American PEN/Hemingway Award. How had I missed it?
