Join Patrick Geoghegan for this month's book show as he talks with the authors of some amazing new history books, including:

• Stephen Kelly's study of Charles Haughey's fractured relationship with Northern Ireland
• An account of the Irish who helped shape modern South America, by Tim Fanning
• Brendan Kelly's history of psychiatry in Ireland
• Mark William's exploration of Irish mythological gods and how they have been cast and recast in literature
• And Neil Faulkner's new history of the Russian Revolution, that sees 1917 as an explosion of democracy
