Dominic Pattison's life is one of level contentment: his marriage has proved happy and durable; his business, too, is successful. And then Sam Williams, a builder and ex-squaddie, claims to be his son. Yet is Sam who he says he is? After almost thirty years, Dominic can remember little of the affair with Sam's mother. His instinct is to recoil from this aggressive and volatile stranger, who could, with just a few words, take his life apart. But Sam refuses to be dismissed. With its deft switches of sympathy between menaced 'father' and rebuffed 'son' and its exploration of the intricacies of memory, this will resonate long with its readers.
