HE'S A DETECTIVE. SHE'S A WITCH.

FOUR ARTEFACTS, ONE RITUAL. POWER ALWAYS COMES WITH A PRICE.

In the quiet village of Thornhope, peace never lasts long.

When a series of strange artefact thefts sweeps through Lancaster, Detective Inspector John Spencer thinks it's another case of greed and opportunity. But when the clues start to trace back to Thornhope's old families-and one particularly dangerous book- there's only one person he truly needs.

Edith Postlethwaite has seen enough dark magic to last a lifetime, but when the thefts begin to form a pattern-four artefacts, four names, one impossible ritual-she realises the danger isn't buried in the past. It's waking up.

As John and Edith dig deeper, they uncover a circle of students who've stolen far more than relics. What they've taken could tear open a doorway between worlds-and once it opens, nothing human will be able to close it.

Together with Kate, Dan, and the world's most opinionated goat, John and Edith must unravel the truth before the ritual is complete.

Because some doors are locked for a reason.

And some thieves don't know when to stop stealing.
