In her review of Monopolising the Master, Anne Diebel briefly mentioned my father, Michael Swan. In a 1955 piece for the London Magazine, he’d quoted liberally – and without permission – from James’s letters to the sculptor Hendrik Andersen. The letters were astonishingly candid and indiscreet, and loaded with exclamation marks. It’s also astonishing that the London Magazine and Harper's Bazaar, which reprinted the piece, weren’t sued by the estate.
