A delightfully disgraceful romantic and often dangerous romp through the 18th century Georgian Age of Enlightenment by Adam Blake, the illegitimate son of Sir Francis Dashwood, Master of the Hellfire Club of the Monks of Medmenham Priory and Annie Blake an orphan from the Foundlings Hospital in London.

With the endorsement of King George III and the threat of war increasing between England and France over the independence of the American Colonies, Adam is reluctantly groomed as an agent of the Crown by the King's Spymaster Viscount Barrington and sent to America.

Charles Beaufort Duc De Montmerency, a French agent who has murdered Countess Caroline Adam's first love, has sworn to kill Adam after having been wounded by him and thwarted in his attempt to establish a spy network.

The security of Britain the fortunes of its army and the safety of its spies rest in Adam's hands, whilst he is torn between Lady Eleanor, a fellow spy, and Sophia Schwartz the self professed daughter of his deceased mentor. But all is not as it seems as intrigue and danger rush Adam towards an unexpected and deadly conclusion.
