The Photograph has sold over 10,000 copies in hardback. In paperback Spiderweb and Heatwave have sold over 43,000 and over 47,000 copies respectively. Searching through a little-used cupboard at home, Glyn Peters chances upon a photograph he has never seen before. Taken in high summer, many years earlier, it shows his wife, Kath, holding hands with another man. Glyn's work as a historian should have inured him to unexpected findings and reversals, but he is ill-prepared for this radical shift in perception. His mind fills with questions. Who was the man? Who took the photograph? Where was it taken? When? Had Kath planned for him to find out all along? As Glyn begins to search for answers, he, and those around him, find the certainties of the past and present slip away, and the picture of the beautiful woman they all thought they knew distort.
