The Stone of Madness

Henry Price and Pearly Black are the most brilliant alchemists of their generation, but as their unique metaphysical talents flourish, their friendship deteriorates into a bitter feud.

Following Black’s establishment of a shadowy organisation with dark, inscrutable goals, the men are firmly set on a collision course that culminates in Black’s death at the hands of his rival.

Ten years later, the theft of an obscure sixteenth-century manuscript hiding a powerful secret forewarns Price of a resurgence of Black’s former cultist allies, pitting an eclectic mix of alchemists, murderers, thieves, media tycoons, spies and academics against one another in a search that is seemingly being controlled from beyond the grave.
