On the North-West frontier of India stood the little fort of Darlinger. It had been erected two years previous to the opening of this story, and was occupied by three companies of a Punjaubi regiment under the command of Major Ackworth. It was intended to act as a check to the incursions of the fierce tribes across the frontier. One of these raids had recently been made, and the major was about to start with two and a half companies and two field-guns to punish the invaders. He was a strict officer but not unpopular, being very particular about the comfort and well-being of those under his command; in other respects, however, he was a silent and reserved man. He had lost his wife a year before, and this had completely broken him down; the only being he seemed now to care for was his daughter Nita. Nita's mother had intended to return to England with her daughter just before death put an end to the plan.
