Harry and Freya Kipling buy an unremarkable painting at a car boot sale for the sake of its rather attractive frame. Cleaning it at home, they find something else beneath the surface - a landscape that may be a lost masterpiece from 1770, worth millions to the right buyer. But the wrong buyer has already found them. Detective Superintendent Roy Grace, meanwhile, is reopening a cold case: an art dealer, murdered and forgotten. The connection between the two, when it comes, is brilliantly plotted and lethal. James is working at the very top of his form.
