Book excerpt: Admiral of the Fleet Lord 'Jacky' Fisher (1841-1920) was one of the greatest naval reformers in history. He was also a colossal figure to contemporaries, both loved and loathed, a man of exceptional charm, presence and charisma. Since the late 1940s, Jan Morris has been haunted by his face - with its startling combination of 'the suave, the sneering and the self-amused.' This evocation is both biography and a love letter, a perfect expression of her passionate interest in mavericks and outsiders, in travel, ships and the glorious pageantry of the British Empire in its prime.
