Gravel's explosive monthly series continues! The ancient Sigsand Manuscript, now in the hands of the Minor Seven, is far too powerful to be possessed by Britain's great Occult Detectives. At least, that's Combat Magician William Gravel's opinion, as he continues his quest to collect all six pieces of the supernatural text from his former associates. But the next man on Gravel's hit-list has found him first, and on the dark and fog-shrouded highland moors, a surprising confrontation will take place with an outcome that Gravel could never have anticipated. Sykes, the oldest of the Minor Seven, is one of the few still alive who personally knew the Sigsand's previous owner, Thomas Carnacki. But will Gravel survive long enough to hear the finale of one of Carnacki's most astounding cases or will the black hellhounds that accompany Sykes end Gravel's quest at its midpoint?
