A dark past casts a deep shadow.

Evan Warlow is back in the saddle as a DCI, though he isn’t yet sure he deserves to be, and there are others who share his doubts.

When a brutal attack on two mountain bikers in the vast solitude of the Brechfa forest leaves one dead and the other badly injured, the hunt is on for the killer. And though the evidence points firmly in one direction, an open and shut case soon becomes murky and unclear.

It’s not the first time bad things have happened in these woods. Things that some have tried desperately to forget. But for the killer, it’s more a matter of unfinished business. 

Unless Evan and the team can outwit a vengeful and clever murderer, someone else is going to die.
