Hell's Gate (DCI Bennett)

A domestic dog attack on a child leads to a complex case - the macabre discovery of indiscernible body parts amongst bin bags littering a road on the outskirts of town. Meanwhile, a team of criminals spreads its tentacles across the sordid underworld of people trafficking, dog fighting, prostitution and murder. Is there a link between these cases, and can DCI Bennett catch a twisted killer before he strikes again?
