The twelfth instalment in the Merrily Watkins series: When a man's body is discovered near the picturesque town of Hay-on-Wye, his death appears to be 'unnatural' in every sense. Merrily Watkins is drafted in to investigate.

An unnatural body, a town steeped in black magic, and maddening isolation--has paranormal advisor Merrily Watkins finally met her match?

A man's body is found below a waterfall. It looks like suicide or an accidental drowning--until DI Frannie Bliss enters the dead man's home. What he finds there sends him to Merrily Watkins, the Diocese of Hereford's official advisor on the paranormal. It's been nearly 40 years since Hay was declared an independent state by its self-styled king--a development seen at the time as a joke, a publicity scam. But behind this pastiche a dark design was taking shape, creating a hidden history of murder and ritual-magic, the relics of which are only now becoming horribly visible. It's a situation that will take Merrily Watkins--alone for the first time in years--to the edge of madness.
