In the Spring of 1857, with India on the brink of a violent and bloody mutiny, Krishnapur is a remote town on the vast North Indian plain. For the British there, life is orderly and genteel. Then the sepoys at the nearest military cantonment rise in revolt and the British community retreats with shock into the Residency. They prepare to fight for their lives with what weapons they can muster. As food and ammunition grow short, the Residency, its defences battered by shot and shell and eroded by the rains, becomes ever more vulnerable.
