Telling David’s story in this splintered fashion, woven into a much wider one, is, of course, true to how it feels to experience another’s life from the sidelines. It is as though John is working his way backwards to make sense of the extraordinary thing that had been under his nose but at the time had simply passed him by. “I had no perception he was to become one of the greatest artists of the 21st century. He quietly kept his own counsel about his life plan.”... Are there points to criticise? Perhaps the recounting of each sibling’s achievements drifts toward the Christmas round robin, and the bits about grandparents aren’t hugely enlightening. But it would be silly to quibble about these moments, because the essential treatment is so enormously appealing: good-natured, bluntly told, skimmed with Yorkshire humour.
