India, in the mid-nineteenth century, was virtually run by a British commercial concern, the Honourable East India Company, whose directors would pay tribute to one Indian ruler and then depose another in their efforts to maintain their balance sheet of power and profit. But great changes were already casting shadows across the land, and when a stupid order was given to Indian troops to use cartridges greased with cow fat and pig lard (one animal sacred to the Hindus and the other abhorrent to Moslems) there was mutiny. The lives of millions were changed for ever including Arabella MacDonald, daughter of an English regular officer, and Richard Lang, an idealistic nineteen-year-old who began 1857 as a boy and ended it a man.
