Tom Hart Dyke's book about his kidnap and the idea to create a world garden at his ancestral home Lullingstone Castle is 'The Cloud Garden'. Lullingstone Castle has just opened for the summer season. Gary Enstone, as House Steward and conservator at Bateman's in East Sussex explains how dust, water, and 10,000 visitors a year can play havoc with historic properties if not meticulously tended, and why he likes to taste the dust. Bateman's is open all year round.

Antonia Bolingbroke-Kent says the biggest challenge on her two thousand mile motor-bike ride through Vietnam, Laos and Cambodia was going it alone.

JP Devlin meets Abba super-fan, Jason Tuazon-McCheyne from Melbourne, and Jimmy Osmond, chooses his Inheritance Tracks - Moon River by Andy Williams and 'He Ain't Heavy He's My Brother' by The Osmonds, reflecting how close he is both to his siblings and his four children.
