Seven Gifts of Madness

Investigators Atticus and Lucie Fox are summoned to an estate in remote Northumberland where a series of bizarre, grisly deaths appear to center 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.
