Musing upon the art of biography, Virginia Woolf bemoaned the constraints that facts imposed on imagination. It is the most ‘restricted’ of all arts, she wrote, limited by ‘friends, letters and documents’. Yet these very restrictions can inspire creativity. Good biographers don’t just accumulate facts; they give us, in Woolf’s words, ‘the creative fact; the fertile fact; the fact that suggests and engenders’. Biography, done well, Woolf concluded, does ‘more to stimulate the imagination than any poet or novelist save the greatest’. By this definition, Julia Laite is indeed a superb biographer.
