A bloody pig’s head nailed to a wall… Investigate journalist Emma Hunter is in the thick of another cold case featuring a game of truth or dare in a dark forest by a Dorset army base 15 years ago that went horribly wrong. Four girls went in, only three came out. A Wiccan map splattered with red ink… Wreathed in mist and memory, the barracks offered no remains of any kind, just a hole in the perimeter fence and years of unanswered questions. An ancient ritual drenched in death… But when Emma teams up with fellow firebrand reporter Rachel and whip-smart cold case expert Jack, she soon discovers it wasn’t a game at all as a grand and sinister pattern begins to unfurl around them.
