London, 1938. In the suburbs of the city, an ordinary young housewife has become the eye in a storm of chaos. In Alma Fielding's modest home, china flies off the shelves, eggs fly through the air; stolen jewellery appears on her fingers, white mice crawl out of her handbag, beetles appear from under her gloves; in the middle of a car journey, a terrapin materialises on her lap. Nandor Fodor - a Jewish-Hungarian refugee and chief ghost hunter for the International Institute for Psychical Research - reads of the case, and hastens to the scene of the haunting. But when Fodor starts his scrupulous investigation, he discovers that the case is even stranger than it seems. By unravelling Alma's peculiar history, he finds a different and darker type of haunting: trauma, alienation, loss - and the foreshadowing of a nation's worst fears.
