The vile triple curse was as old as Evil itself. Spawned in the dark and magical past, nurtured by hate through the centuries, it burst now from the contorted lips of Fergus Trayle, Hermit of Black Loch, thwarted in lust. And it spelled doom for Sir Alistair Rathlaw, the man who had thwarted him, and all of hi Clan.

Only THE GUARDIANS, committed to their never-ending war against the malignant forces of The Supernatural, could aid Sir Alistair in his desperate plight. From The Hermit's foetid hut, secret divinations would lead them to modern Glasgow, where suave, sophisticated Cosmo Trayle pursued his satanic brother's hideous aims. But not all THE GUARDIANS' knowledge and power might avail them in that last terrible moment - when an unspeakable Black Sabbath rite threatened exotic torture and death to the last heir of the noble House of Rathlaw.
