A Cathedral of Demons
(2026)(The third book in the Griffin Woodbury Supernatural Detective series)
A novel by Joe Talon
A dark supernatural thriller of revenge magic, demon summoning, and a ritual to trap heaven itself.
Beneath the spires of Truro Cathedral, something evil is waiting to be unleashed.
When a ritual killing draws DoPI operative Griffin Woodbury to Truro, it looks like another para-event until the pattern emerges. Four children, all born at the same moment. Three already taken. The last is in hiding.
The trail leads back decades.
Dr. Elena Grove was fifteen when the Church took her daughter. Five years later, they told her the child was dead. Now, after a lifetime of cold, calculated rage, she’s ready to answer that loss with something far worse than vengeance.
She’s building a ritual beneath the cathedral, one designed to summon demons and force Heaven itself to intervene.
And when the angels come, she plans to trap them.
As a possessed killer stalks the investigation and the veil begins to tear, Griffin is pulled deeper into a conflict that blurs the line between faith and weaponised belief. With time running out and the final child in her grasp, Grove’s endgame becomes terrifyingly clear.
This time, it’s not just about the dead.
It’s about what comes for the living and the reckoning waiting for the Church of England.
A Cathedral of Demons is Book 3 in the Griffin Woodbury Supernatural Detective series, perfect for readers who love Jim Butcher, Helen Harper, and dark, high-stakes supernatural thrillers.
This book contains themes around baby loss and forced adoption that may be unsuitable for some readers
