Loyalty - S2.E1

In the first of a two-part story, the badly burned body of a disabled man turns up in a remote part of Manchester and a few days later another corpse is discovered. The detectives start to realise the victims were not just murdered, but tortured too. They make an arrest, but it becomes clear their investigation has just scratched the surface. Meanwhile, Janet throws her husband out and Rachel's estranged brother turns up on her doorstep. With Lisa Riley and Pippa Haywood.
