The queer witchy fantasy murder mystery series concludes in one last mystery for Mallory, Cornelia and Diana, as they have to solve their biggest, and most important case of all - who killed Theodore. Perfect for fans of supernatural mysteries and cosy crime by authors such as Ben Aaranovitch, Josiah Bancroft and Tammie Painter.
It’s three days until Samhain, and the Undetectables are going to die. No longer taking magical cases (not that anyone would hire them), they’ve well and truly given up the ghost.
Meanwhile, Theodore (the relinquished ghost in question) is on the run. Wanted in connection with the Undetectables’ last case, he’s hiding in the last place anyone would think to look, keeping secrets (badly) and forming unlikely alliances (slightly less badly).
When a copycat killer emerges and history appears to be repeating itself, the Undetectables are called up for one last case. Mallory, Diana and Cornelia find themselves in a final race against the clock – but this time, the whole of Occulture is at stake.

Why can’t I buy a preorder with any other item?
We work to process orders as soon as they’re placed so that you get your delivery as quickly as possible in one go.
Preorders are not immediately dispatched as they are delivered upon the respective release date. This means there will be a wait between placing your order and receiving your order.
If you need to add more items to your basket, we recommend placing a separate order for this. We will send out all the items in your order in one delivery and preorder items will always arrive just after their respective release date.
Can I cancel/amend my preorder once it’s placed?
If you’ve purchased a preorder title but noticed a mistake on your order, please contact our online team at customercare@bookstation.ie and we will try to fix this for you before the book is released and dispatched.
Once your order is shipped and physically in transit, we can no longer offer any amendments to your order.

Can I cancel/amend my order once it’s placed?
Once your order is placed we work as quickly as possible to dispatch your order to you so we cannot promise this is always possible.
