Northumberland traffic cop Sal Delaney must keep her head in the game to solve a complex murder with dark motives in this pulse-pounding, gritty police procedural by Sunday Times bestselling author David Mark.

'Mark is a superbly gifted writer' Booklist Starred Review

You can be so fascinated by demons and the afterlife that you don't notice the monsters all around you.

Northumberland. Collision Investigation Officer Sal Delaney is at a road traffic accident scene near the infamous Bael Hill Farm - locally labelled the Murder House - when a body is discovered at the lot.

It turns out local hermit Rollo Savage took his own life, but something doesn't add up. At first glance he seems to have hanged himself, but other evidence hints at murder.

Rollo's past earned him a lot of enemies, but who would hurt the kind old man after all these years? Soon Sal is caught up in another twisted and dark case, one which shockingly seems to involve people she holds dear . . .

For fans of David Mark's critically acclaimed DS McAvoy Mysteries as well as readers of Val McDermid, Ian Rankin, Denise Mina and Peter Robinson.
