"In a nutshell." he began, taking a deep breath, "some joker–some extraordinarily talented joker–says he’s going to frag up every computer system on the planet and gives every indication that he’s more than capable of fulfilling such a threat. He leaves an icon, a calling card, which is the most famous fraud in Christianity. He names himself after the greatest genius in the world’s history. I’m asked to find out all I can and maybe find him. I no sooner start making attempts to do so than an awful lot of people start getting very interested in that. One of them sends our party guest last night. One of them tracks Geraint and ends up dead at the hands of jesuits. At first I didn’t know what the image meant, the face of a black woman, but now it looks as if some very weird occult or religious stuff is involved. And that’s what Serrin’s helping me with. And, oh, we have seven days before our joker pulls his party piece–the systems crash and the world grinds to a halt. Okay?"
