'Eighteen months before his 70th birthday, Christopher Lambert drew a blue line across the map of Europe. Seventy one walking days and over 1000 miles later, with a small rucksack, the most important contents of which were a water bottle and a spare pair of socks, he arrived in Rome. In his pocket he carried a sketch-book and some coloured pencils. The book he subsequently published, 'Taking a line for a walk', faithfully reproduces the the journal he kept.'
