I chose this as my next Mrs Bradley because the stone circle of the title is supposedly based on one I went past earlier this year, but having read the book, it's bloody not – Winterbourne Abbas may have crept closer to the Nine Stones since the forties, but I'm fairly sure they haven't been relocated to the valley from the hill up which the Dancing Druids stand. Still, they add a pleasing folk horror tinge to a case which mixes eerie locations – see also the house with the four dead trees – and an uncharacteristically action-packed investigation, all smugglers and mysterious kidnappings, like the Famous Five with the level of dismemberment and gunplay we might have expected from Nicolas Winding Refn, as against the comparatively restrained approach he actually employed. This is not the only unexpected direction; Mrs B's strapping sidekick Laura, engaged since the previous book, now demonstrates mild hesitation about getting her kit off at the least provocation, and even Mrs B herself at one point claims "I have a fatal habit of recapitulation due to having to lecture to people who won't read books but have been brought up on a diet of films and the wireless." All I can say is, she does a sterling job of not letting it get the better of her in the other ones I've read. But if the lineaments are more conventional than some of her outings (the crime takes place at the beginning of the book, for one thing, and is the sort of set-up – a lost cross-country runner mistaken for an expected accomplice – that's suitably atmospheric, but which one can imagine other sleuths, less strange than Lestrange, also tackling), the result never falls as flat as some of the restrained entries in the series, and certain details remain resolutely unexplained: what was it about the number nine? But, frankly, the main thing with any series detective story for me is that we get to see the regulars just being themselves, and this one has some delightful business for George the chauffeur, plus, well: '"Aunt Adela is very full of beans today," said Denis. "She feels she's up to mischief, and that, in my experience, always makes old ladies very cheerful."'
