"It begins innocently enough, with the death of a prostitute in Bedford Square, London. She isn’t the first ’flower girl’ to die and she won’t be the last, not now the killer had a taste for it.
The man, Nathaniel Seth, is one of the Brethren, a shadow society of occult dabblers and black magickers who hide away in the darkest parts of the city, in corners where they could not be seen by polite society. Little did Seth know that his own life was only hours from ending, his flesh to be taken as host for a daemonic entity clawed all the way out of hell’s pit in the centre of the hollow earth because Seth himself breached the Catamine Stair. Now things are afoot. Strange things. The lions of Trafalgar have fulfilled their prophecy, climbing down from the plinths around Lord Nelson’s column to defend the city. The daemon is out, stalking tender prey through the gaslit streets, meat markets, fish stalls and slaughter houses of Whitehall. He has a taste for women, though not ordinary women. These women are different. Special. They may look like whores but they have the blood of angels flowing in their veins. If he can kill enough of them, bathing in their innocent blood, then the daemonic Seth believes he can open the ancient Ald Gate--one of the seven great gates of London--the last gate to Eden, and go home, even if it means tearing London herself apart.
A group of steadfast men stand in the daemon’s way, led by Fabian Stark, a man himself doomed to die before even the first die is cast, and each of them cursed in their own way: Dorian Carruthers, Haddon McCreedy, Eugene Napier, Anthony Millington, and Brannigan Locke. The Grayfriar’s Gentleman’s Club."
