Ritwik Ghosh, twenty-two and recently orphaned, finds the chance to start a new life when he arrives in England from Calcutta. But Oxford holds little of the salvation Ritwik is looking for. Instead, he moves to London, where he drops out of official existence into a shadowy hinterland of illegal immigrants. The story that Ritwik writes to stave off his loneliness begins to find ghostly echoes in his own life. And, as present and past of several lives collide, Ritwik's own goes into free fall.
