Silas Marner (1861) is Eliot's classic tale of an outsider.
A weaver who comes to live & work alone in the Midlands
...Detective Hanlon is addicted to violence. She likes the rush, the danger, the losing control...
When Hanlon is suspended
...An old man is walking alone late at night when he is threatened on the street by 3 armed thugs who attempt to mug him. They die. The police are baffled, & decide it must be the symptom of a drugs war. There then follow more 'unexplained' deaths & accidents, all of which fox the police & lack any obvious evidence to lead them to an arrest.
