The border zone between history and fiction can be dangerous territory. When, if ever, is speculation acceptable? Is invention justified? Can fictionalising history advance the understanding of truth? Pre-eminent British historian Antony Beevor takes on local creative non-fiction writer Joanna Grochowicz and historical fiction novelist Rosetta Allan in a light-hearted consideration of the pros and cons of monkeying with the historical record. Chaired by Hannah August.
