Detective Superintendent Tom Harper senses trouble ahead when the prime minister plans a visit. Can he keep law and order on the streets while also uncovering the truth behind a missing child?

Leeds, September 1908. There’s going to be a riot. Detective Superintendent Tom Harper can feel it. Herbert Asquith, the prime minster, is due to speak in the city. The suffragettes and the unemployed men will be out in the streets in protest. It’s Harper’s responsibility to keep order. Can he do it?

Harper has also received an anonymous letter claiming that a young boy called Andrew Sharp was stolen from his family fourteen years before. The file is worryingly thin. It ought to have been bulging. A missing child should have been headline news. Why was Andrew’s disappearance ignored? Determined to uncover the truth about Andrew Sharp and bring the boy some justice, Harper is drawn deep into the dark underworld of child-snatching, corruption and murder as Leeds becomes a molten, rioting city.
