A spooky and darkly comic adventure set in Cornwall - Famous Five with a twist. Orla thought she was in for a relaxing family holiday, but when she finds a mysterious glowing necklace in the woods, it turns out there is a slight possibility she may have uncovered an ancient curse. After meeting a coven of old ladies, it becomes clear that Orla's arrival in Poldevel is no longer a coincidence.

She's the only one who can solve this mystery, and she'll need help from the only other member of the family with good instincts - Dave the dog.
