Autumn 1930. As the nights draw in, Jacob Flint attends a séance. He's intending to investigate fraudulent mediums – but then a ghost appears with a message from the spirit world: 'Felix Reilly murdered me.'
The same evening, Rachel Savernake takes on an intriguing case. Ulick Quayle was investigating the three-hundred-year old story of The Witch of Blackstone, burned at the stake for her supposed murder of the local Lord. Now Ulick's body has been found on bleak and eerie Blackstone Moor, his corpse ripped to pieces.
Some of the villagers believe the Witch of Blackstone has returned from the dead. The police suspect an escaped inmate from a nearby asylum. But Ulick's sister is convinced that the culprit is someone much closer to home – and she's employed Rachel to investigate.
As Rachel starts to unravel a bizarre crime with its roots in the deep past, her friend and sometime lover Jacob is on a similar trail of murder and witchcraft. And both are leading to the ancient stone castle of Blackstone Tower...
Blacktone Fell explores the shadowy borderlands between spiritual and scientific; between sanity and madness; between sin and virtue. This is a mystery involving clerics, historians, scientists... and people who believe that Blackstone is a place controlled by dark and demonic forces, which might just take human form.
