MS is good at describing bleak places, so when I finally visited Dartmoor many years after first reading the book, I recognised what I was looking at. And five stars for this one, because it's a cracking story, even if it does involve flying saucers (although frankly they are more believable than the apparent ability of the Lone Piners to undertake a 17 mile bike ride at the drop of a hat). An exciting climax even by Lone Pine standards, and Jon's choice of words after knocking out Green adds some unintentional humour for the modern reader.
