London, 1938. Alma Fielding, an ordinary young woman, begins to experience supernatural events in her suburban home. Nandor Fodor - a Jewish-Hungarian refugee and chief ghost hunter for the International Institute for Psychical research - begins to investigate. In doing so he discovers a different and darker type of haunting: trauma, alienation, loss - and the foreshadowing of a nation's worst fears. Shortlisted for Baillie Gifford Prize 2020.
