When they'd finished with the magazine, it was time for show-and-tell. Mark was a collector even back then, and had got his hands on something special. He took it out of his shoulder bag, looking quickly about to make sure no-one was watching, then laid his find reverentially on the table before them. Henry and Charles looked dubiously at the cardboard box full of tatty, handwritten pages.

"All right," said Walker. "What is it this time? And it had better not be about Roswell again. I am sick to death of Roswell. If anything had really happened there, we'd know about it by now."

"You just wait," Mark said darkly. "I'll get you proof yet. I know someone who knows someone who claims one guy actually filmed the autopsy on the aliens... Of course, this is the same man who claims we'll be landing men on the moon in two years, so ..."

"What have you found, Mark?" Charles said patiently. "And what good does it do us?"

"Is it something we can blackmail people with?" Walker said wistfully. "I've always wanted to be able to blackmail someone."

Mark grinned wolfishly, one hand pressed possessively on the pile of papers, as though afraid someone might sneak up and steal them. "This, my friends, is the real thing. The mother lode. An unpublished manuscript by the one and only Aleister Crowley-the Magus, the Great Beast, the Most Evil Man in the World. If you believe the newspapers, which mostly I don't. But Crowley was the real thing, for a time at least, and there have always been those who said his best, or more properly his worst, stuff was never published. This manuscript was apparently put on the market some years back, when Crowley was desperately short of money, but no-one was interested. He was out of favour among the conjuring classes, and the papers were bored with him. Eventually a copy of this manuscript turned up at the International Times, and a sub-editor there passed it on to me, in return for a complete set of Mars Attacks! cards. Unlike most of the fools whose hands the manuscript passed through, I actually read it from end to end, and I am here to tell you, my friends ... this is the answer to all our prayers. A direct means to our much desired end."

"God, you love the sound of your own voice, " said Henry. "What is it, Mark? Not just another grimoire, I hope."

Mark was still grinning widely. "One chapter in this manuscript describes a particularly powerful spell, or Working, that Crowley began but never dared finish. And let us not forget, Crowley dared a lot. He started the Working, to summon and bind to his will a most powerful Being, but abandoned the ritual after catching a glimpse of just what it was he was attempting to summon. Beautiful, terrible, he wrote ... and that was all. He ran away from his splendid home on the bank of a Scottish loch, and never returned."
