Kamil Rahman is a cook in a Brick Lane restaurant. But he used to be a detective back in Kolkata. And somehow trouble still knows how to find him. When a young woman Kamil knows is murdered the police are convinced her boyfriend is the culprit. Kamil isn't so sure and feels he has no choice but to start his own investigation. Meanwhile, his friend and restaurant manager, Anjoli, is troubled by a rise in the number of homeless deaths in their local area. The cases seem unrelated and as the duo dig deeper, discovering tentacles that stretch from Lahore to London, they find themselves in grave danger. Together they take on the indifference of the authorities to the homeless and the casual racism that pervades the investigation of killings of Muslims - all while a supremely intelligent murderer is manipulating events to stay several steps ahead of them.
