A body in the forest. An ancient pagan ritual. A baffling mystery.

On Halloween night, the body of a young woman is discovered buried in a shallow grave in the Dragon Forest, a popular local beauty spot. The only clue to her identity is the number 37 tattooed on the sole of her foot.

Detective Norman’s new boss, Acting Superintendent Evans, is convinced the murder is connected to a group of pagans who were performing a secret ritual in the forest that night.

Norman’s not so sure. The one thing he does know is that he’d make much faster progress without the insufferable Evans breathing down his neck.

Something is off about this case. Norman knows he’s missing something important — but he can’t seem to see the wood for the trees.

Then the discovery of a second body in the woods turns everything on its head.
