Edge of Darkness

Yorkshire policeman Ron Craven sees his daughter Emma gunned down in front of him. His grief leads him to investigate and he learns of her activities as a radical environmental activist.

The police close in on their prime suspect for Emmas murder but Craven, now aware of her activities, is convinced that his colleagues are on the wrong track.

Craven and Jedburgh follow the GAIAs route into Northmoor nuclear plant, but others are determined to stop them.
