In the first ever Lives in a Landscape, the Ancient and Honourable Society of Ratters leave London clubland behind and head for Yorkshire to experience the excitement of a real rat-hunt, masterminded by ex-miner Brian Oliver. But when he invites them back to his council semi, it's not quite what they're expecting. Alan Dein has presented the programme since 2008 - before then, most editions were audio montages without a presenter. Producer: Laurence Grissell
