Something scared Nuala Flaherty to death. When her body is found in the centre of a pentagram on a lonely moor, Rebecca is determined to find out what. Was she killed by supernatural means, or is there a more down-to-earth explanation?

Rebecca's investigation leads her to a mysterious cult and local drug dealings. But what she doesn't know is that crime matriarch Mo Burke still has her in her crosshairs. Mo wants payback for the death of her son, and after one failed attempt to hurt Rebecca, she is upping the ante. And this time, it could be lethal.
