Commissioned Investigators Atticus and Lucie Fox are summoned to an estate in remote Northumberland where a series of bizarre, grisly deaths appear to centre on the delusions of a madman who lives alone on the edge of the moors. Close-by are the remains of a long-vanished castle where local legends say King Arthur still lies in an enchanted sleep, waiting to be awoken at a time of great need. The killings have all been committed using Arthurian artefacts and the locals swear that they have seen a ghostly knight in armour roaming the moors. But how can that be? This is 1890 and King Arthur died over thirteen-hundred years before.
