He also has written a foreword to the reissue of the books 'The Living Stones' and 'The Crying Of The Wind' by Ithell Colquhoun originally published in 1957 and 1955 respectively. He's long evidenced an interest in the Neolithic/Bronze Age. I've not read the latter but the former, which deals exclusively with Cornwall, is well worth anyone's time. They're published by Peter Owen Publishers in paperback, £9.99.
