Which two sentences contribute to the overall eerie mood of the adapted excerpt from "The Fall of the House of Usher" by Edgar Allan Poe?
In this mansion of gloom I now proposed to myself a stay of some weeks. Its proprietor, Roderick Usher, had been one of my closest friends in
boyhood. But many years had passed since our last meeting.
A letter, however, had lately reached me in a distant part of the country. A letter from him, which, in its wildly insistent nature, had allowed no other than
a personal reply.
The handwriting gave evidence of nervous agitation. The writer spoke of a kind of illness--of a disorder which oppressed him--and of an earnest desire
to see me.
As his best and indeed his only personal friend, with a view of attempting, by the cheerfulness of my society, to provide some relief from his malady.

2. As his best and indeed his only personal friend, with a view of attempting, by the cheerfulness of my society, to provide some relief from his malady.

These two sentences convey a sense of foreboding and forewarning, foreshadowing the eerie events that are to come in the story. The first sentence notes the nervous agitation evident in Usher's handwriting, which suggests some underlying anxiety or unease. The second sentence further highlights Usher's isolation and the sense of unease in his letter, as he pleads with the unnamed narrator to come and provide him with some relief. This combination of nervous agitation, isolation, and foreboding sets the tone for the eerie and unsettling events that will be revealed in the rest of the story.
