Intrigue and imminent danger await the young men brave enough to join "The Great Game," the political conflict between Britain and Russian Empire. Captain David Ingle is one the bravest, as he saves a Fort in India from attack, disguised as a Muslim holy man. Returning to Calcutta, David is congratulated by the viceroy for service to his country, but warned that the Russian agents he thwarted now threaten his life. More importantly his grandfather, the Marquis of Inglestone, has died and the family title and estate are now his. But he returns to a dilapidated estate, because the old man hid the family treasure.
