Rupert Harry Miller is a designer and author. His autobiography, Life of a Salesman, tells how he honed his salesmanship skills in Eastern Europe in the 1990s. The story of his colourful antics is clouded by the death of Rupert's brother, Julian, who suffered from haemophilia and died after developing Aids from the contaminated blood he received as part of his treatment. Life of a Salesman is published by Spiffing Covers.

Adam Cohen is a Canadian singer and songwriter. His fifth album, We Go Home, was recorded in several locations including the Greek Island of Hydra, where he spent most of his childhood, and Montreal, the city of his birth. Adam is the son of Leonard Cohen, celebrated for songs such as Hallelujah, Bird on the Wire and Suzanne. We Go Home is released on Cooking Vinyl. Adam is touring Europe.

Sir Tim Smit is a Dutch-born British businessman who, with John Nelson, rediscovered and then restored the Lost Gardens of Heligan in Cornwall. The gardens had slipped into decline after the estate's workers had left to fight in the First World War. Sir Tim is also co-founder of the Eden Project, an environmental tourist attraction. The Lost Gardens of Heligan celebrates the 25th anniversary of its rediscovery with a photographic exhibition of The Lost Images and a walk through the garden.
