Anthony Quinn - Border Angels [Kindle azw3]

On the Irish border, Inspector Celcius Daly investigates human trafficking and a scorched corpse
The border between Northern Ireland and the Republic is a rugged place: cold, windswept, and dark. For the girls brought here from Eastern Europe, it may as well be a war zone. Put to work in a farmhouse brothel near Dunmore, the women are forced into a living hell. One night, a pimp takes one of them for a ride. She is just planning her escape when the car explodes. The next morning, there is nothing left but the pimp's charred body and the woman's footprints in the snow.
As his forensics specialists turn their attention to the burned corpse, Police Inspector Celcius Daly obsesses over the footprints. Where exactly did the woman come from, and where did she go? It is the sort of question asked only in the borderlands--between North and South, between life and death.
