Were the Gallery’s treasures gifts or loans? Was Lord Beaverbrook careless or devious? Jacques Poitras sifts through the personal correspondence, takes stock of the witnesses and testimony at the 2006 arbitration hearings, and interviews the combatants of a bitter legal battle that rocked the art world on both sides of the Atlantic. Deftly connecting the pieces of this historic jigsaw puzzle, he tells a fascinating tale peopled with an arresting cast of characters — from the self-proclaimed “master propagandist” to the present-day heirs of the Beaverbrook legacy.
