Dorothy and Solomon live in a new housing estate on the outskirts of an English village. She’s recently bought her bungalow; he’s recently become the night watchman. He is black, an immigrant. She is white, a recently retired music teacher. They are both solitary, reticent outsiders. When they move tenuously toward each other and their paths briefly cross, neither of them can know that it will be the last true human contact either will have.
