From out of the bog alongside the ancient track to the fenland village of Hexney, a line of deep freshly-made footprints runs, trodden into the dry surface of the abandoned droveway. Are these footprints, or hoofprints, or what? Triangular, eight or nine inches long, they're set in a line one in front of another. And, each night, the footprints are advancing steadily towards the village. When a young boy's body is found in the marsh, the superstitious villagers' ire is directed at a young stranger who'd taken his picture before he'd disappeared. Photographer Bronwen Powys finds an ally in the mysterious Dr. Alexander Caspian, who's been investigating the footprints—and before long they'll be fighting the dark forces of evil for their very lives and souls. An absolutely chilling tale of horror and redemption!
