The Mouth of the Nile, 9th August, 1798: Admiral Nelson has sent Captain Nathan Peake on a desperate journey across the Middle East to convey a grim warning to British India. Bonaparte's army is poised to deliver a fatal blow to the source of Britain's wealth and power by marching overland to India. Arriving in Bombay, Nathan takes command of the East India Company's naval wing the Bombay Marine an under-armed and poorly crewed flotilla of sloops and gunboats. With these meagre resources he must stop the flow of French supplies to their Indian ally and protect the Company's trade from the pirates and privateers swarming in the Bay of Bengal. But when Nathan discovers the truth behind the East India Company's honourable facade he confronts some tough personal choices and a crisis of conscience even more threatening than the enemy.
