1) H.P. Lovecraft, completely over the edge author and well-known madman.
2) Steven King famous modern-day dark writer.
3) Edger Allen Poe noted literary author and depressive.
4) Hamlet, Shakespeares classic and gory tale featuring necromancy and the death of almost the complete cast of characters by its end.
5) Ruddigore, Gilbert and Sullivans light opera, featuring paintings of Evil Ancestors whom come to life and communicate with the living, fortelling doom.
6) Our Town by Thorton Wilder, a classic play in which is set mostly in the town graveyard as the now deceased communicate to us descriptions of their lives.
Of the 6, neither. I woud suggest John Bunyan if you’re looking for some edifying fiction/allegory.
Re: your other comment on the tracts - there’s nothing “heavy handed” or “biased” about telling people where they stand in God’s eyes. God’s own word is quite clear on the subject of the destiny of those who are not in Christ.
