what is the tone of chapter 8.explain

Chapter 8 serves the dual function of continuing the entanglement of Marner's and Raveloe's affairs, shown in the general interest in the investigation, and of reintroducing us to the doings of the Casses, who have been absent from the novel for quite a while. It is also, like Chapter 4 for Dunstan, a portrait of Godfrey's character at a moment of crisis. The tone is hence dark and dysfunctional much like the Cass family.
