Dark Diamond

Dark Diamond follows Lord Shayista Khan, who governed Bengal in 1685 as Mughal Viceroy under the emperor Aurangzeb, a position of great authority. Under his administration the province grew into a major centre of trade and culture, which made it a target for many rivals. Khan must contend with Maratha fighters, rajas from Arakan, Hindu landholders, zealous mullahs, a sinister Pir with occult powers, and the East India Company.

Alongside these political dangers, Khan has to lift a curse connected to the Kalinoor, a dark diamond said to be the sister of the Kohinoor, which now belongs to the British Crown.
