Who is the narrator in Great Expectations by Charles Dickens?

This is the nickname for Bentley Drummle, which Jaggers had created. Drummle is probably called a spider because he lures unsuspecting prey into his web of jealousy, leaving the prey disoriented and upset (such as Pip). Had Pip seen Drummle before Estella's wedding, he probably would have had a devilish grin on his face just as much as a satisfied spider would.
