Having returning a hero from Russia after recovering the stolen Norfolk Emerald and winning the hearts of Countess Bruce and the Empress, he is raised to be a Knight Companion of the Bath by King George.

Despite his growing notoriety and the hope that he'll be left to lead a quiet life, he once again finds himself with Viscount Barrington the King's Spymaster and the King, who is showing distressing signs of madness. He is told news of the Illuminati, a secret organisation formed recently in Bavaria, who are infiltrating influential British and French society to foment revolution as part of a New World Order.

King George insists that Adam is the man to stop them.

So once more propelled unwillingly into what will be the darkest and most dangerous adventure so far, Adam becomes a Member of Parliament, where he encounters the lovely Sarah, is enrolled into the Illuminati and follows its leader and Adam's new love Lady Penelope Alexander to France.

Joining forces with the French Secretary of State for War and the Lieutenant of the Paris Police against the growing Republican movement, Adam uncovers traitors in the family of King Louis where he finds new love with the wife of a Duke and has to use his martial skills to impress the Queen, fight a duel and confront the Illuminati Rex.

Will the Blake luck be with him and the friends and lovers he's made as he joins the French Musketeers, ignores the orders of Viscount Barrington to return to England and continues to hunt down the Illuminati.
