Tom Stone, skinnyish, fortyish, English, is madly in love with his wife Ann, an Australian in self-imposed exile in London. Pushing forty and expecting their first child, they buy their first, semi-derelict house in Hackney. They believe this is their settled future, despite Tom’s stalling career and their spiralling money troubles. But Ann becomes convinced she’s being shadowed by a local homeless man whose presence seems like a terrible omen.
As her pregnancy progresses she spends hours cleaning and reorganising the house, and sits up all night talking with a new feverish passion. As their child grows, so too does Tom’s sense of an impending, nameless threat. Their home appears beset with vermin, smells and strange noises. On the verge of losing the house, Tom makes a decision that he hopes will save their lives.
