It is in Paris during France's pre-revolutionary Ancien Régime when gambler, socialite and renowned swordsman Napier Gerrard enjoys a life of luxury and leisure. However, his comfortable lifestyle is blighted by the troubled memory of a double murder when, as a teenager, he lived in England with his father, a fencing master to a Royal Duke. Worse still, he was falsely accused of the crimes and only escaped with his life by fleeing back to his native France.
Napier, knowing that he will never obtain peace of mind until he has done what he considers to be the right thing by his father's memory, makes the momentous decision to return to England in search of his father's resting place. He is aware that, with a large bounty on his head, he could expect betrayal at any time.
Once in England, fate intervenes to keep Napier in danger as a series of events come together to set him on a course that will test his swordsmanship and survival instincts to their very limits.
