The geometry of holding hands

Isabel Dalhousie applies her moral philosopher's mind to wrongdoings in Edinburgh, and will have to call upon her powers of deduction and her unflappable moral code to unravel another mystery in the new novel from the bestselling author of The No. 1 Ladies' Detective Agency series.

In Edinburgh, rumours and gossip abound. But Isabel knows that such things can't be taken at face value. Still, the latest whispers hint at mysterious goings-on, and who but Isabel can be trusted to get to the bottom of them? At the same time, she must deal with the demands of her two small children, her husband and her rather tempestuous niece, Cat, whose latest romantic entanglement comes - to no one's surprise - with complications. Even with so much going on, Isabel, through the application of good sense, logic and ethics, will, as ever, triumph.
