I love this book, this novel, about the historical Macbeth, Thorfinn of Orkney. Dunnett's lively mind and comprehensive research provide a dense, demanding, rewarding reading experience. I've read and reread this book so many times that I enjoy dipping into it anywhere, which almost always draws me into rereading from the very first page. I always falter at finding the right words to describe this novel of action and intellect, force and cunning, passion and compassion. History as life, as a dynamic force or field, and thinking --mindfulness, thought undivorced from physicality and action--are the two house-pillars upon which this word-hall is built. The book is intelligent, often gorgeous, often brutal. Thorfinn is a Viking, after all.
Anyway, here's just one paragraph, selected almost at random, that I feel catches Dunnett's lively, observant, worldly style in a few sentences. Here, the people of Orkney are awaiting word of the war in Norway and they gather on the strand as the first ship with news approaches. Dorothy Dunnett's day-job, as it were, was as a portrait painter, and I think you can see some of that artistry even here in a minor paragraph from page 62.
"Instead of a clean half-moon of blue pebbles, the beach was thick as a bere-field with heads: the cloth-bound heads of married women and the shining cloak-fall of hair of young girls, as well as the cloth and leather caps, the untrimmed hair and beards of the farmers, and the smooth chins and snake-moustaches of those who had travelled and fought and fancied a foreign style would make them sound wittier. The roar of talk, as the longship's prow, sixty feet high, cut towards them, grew to a storm, pushing back the kindly sound, the surfing lap of the waves."
