Modern terrorism meets medieval madness in jaw-dropping horror that will make the living envy the dead

As a member of the Counter Terrorist Unit, Sean Doyle thought he'd seen it all; every violent act, every depraved action man could perpetrate against man, but he is to discover that there are much worse things in this world than even he has encountered. Tracking a group of renegade terrorists from London to the Republic of Ireland to discover who is funding them and why, what he discovers threatens not only his life but his sanity too. The trail of terror leads not just across Britain, but to France as well, where the monstrous deeds of a murderer who died 400 years earlier still cast a dark and horrific shadow. In the grisly frames of a stained glass window taken from the home of this vile killer lay the secret sought by so many for so long: the secret of immortality. One man will stop at nothing to get it, and Sean Doyle is about to meet that man.
