His Path of Darkness

A killer hides deep in the darkness… DI Rob Marshall is stuck in Gartcosh, leading the new Behavioural Sciences Unit – a staff of one and a third – where he’s executing a fruitless hunt, profiling every single murder in Scotland just in case they’re serial cases.

But when a young Peebles woman’s body is discovered in Neidpath Tunnel, disused since the sixties, Marshall is called in to consult on a case on his old home turf. Paired up with his replacement, a cop who’s disinterested in the work, Marshall must tread a line between helping and not jumping to conclusions.

As the scope of the case wides, can Marshall find a killer who may have led many down his path of darkness? Or is Marshall on his own road to destruction?

His Path of Darkness is the sixth book in the DI Rob Marshall series, starring a haunted detective who masks his trauma with biting humour. Perfect for fans of Ian Rankin, Stuart MacBride, JD Kirk and LJ Ross.
