Hilary Wainwright, poet and intellectual, returns after the war to a blasted and impoverished France in order to trace a child lost five years before. The novel asks: is the child really his? And does he want him? These are questions you can take to be as metaphorical as you wish: the novel works perfectly well as straight narrative. It's extraordinarily gripping: it has the page-turning compulsion of a thriller while at the same time being written with perfect clarity and precision.
