“You have heard me say many times, Watson, that when the impossible has been eliminated, what remains, however unlikely it may seem, is the truth. But what happens when the impossible cannot be eliminated?”

London, 1895. 

While investigating a case of potential identity theft, Sherlock Holmes finds himself in the middle of a war between the Egyptian Fremasonry and the Hermetic Order of the Golden Dawn for the possession of the ultimate grimoire, the Al Azif, the Book of Dead Names, the infamous Necronomicon itself... 

The Queen of Alboné and her entourage are going to Honoi in a diplomatic mission. Yáxtor Brandan, empirical adept at the Queen’s service, will be among them. But he is not the Yáxtor Brandan he used to be. He has recovered the stolen memories from his past and he is beginning to assimilate them.

Little by little, people and places that until now had no meaning for Yáxtor are becoming more and more familiar and the empirical adept finds himself in the middle of an unexpected exploration of his past. Old forgotten faces from his youth walk his mind halls and begin to give new shape to what he is and what he can become.

The People's Covenant and God's Hammer have raged a Cold War that has lasted for over twenty years. A war without armies, where battles are fought in the dark and information is the most dangerous weapon.

In this world —which sometimes seems the Middle Ages, sometimes the Renaissance and sometimes the Nineteenth Century— lives Yáxtor Brandan, empirical adept at the service of the Queen of Alboné. A relentless, amoral and unscrupulous character, Yáxtor fights to recover his own past as he tries to prevent a new player in the espionage game to end the world, as he knows it.
