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.

Joe Talon is an author used to walking in a place where you're never quite certain if the world is full of rainbows or shadows. Real life holds little interest. Having grown up on Exmoor, Joe has been fascinated by the mysterious and spooky places that dwell in the dark woodlands and quiet combes. In Joe's first series, the world is a little sideways from ours. It is full of shapes moving on the edge of our vision when they shouldn’t and cold spots in warm places. For Joe, there is always the question, 'what would I do if'? When writing crime, Joe tangles with gangsters and dealers, murderers and thieves, all in the small town of Glastonbury. A place known for its otherness. Joe's Cornish adventures once more explore the supernatural blending with real world events. If you would like to know more, do come and join the Taloneers. You can easily find Joe in the usual haunts of writers, (I'm not allowed to give you my digital address). There are all kinds of mysteries and fun to be had. What spare time Joe has is spent with seven dogs, lots of walks, chaotic gardening, and exploring the strange worlds just the other side of what we think we know to be real. Who needs real life when there are books!
