Elliot Weiner is a historian with a passion for Morris dancing and Warren Harding, 'the shallowest President in history'. After Weiner receives a research grant to write a book on Harding's tumultuous life, he gets wind of a trunkful of the twenty-ninth president's billets-doux, rumoured to be guarded by his ancient mistress on her declining Hollywood Hills estate. There's no depth to which he won't stoop, no moral boundary he won't traverse and no preposterous scheme he won't machinate to get at them.
