What two conditions must Montresor fulfill for satisfactory revenge of The Cask Of The Amontillado?
In "The Cask of Amontillado", Montresor must not only punish Fortunato, but punish him "with impunity". Furthermore, he had to let Fortunato know that he was the one who "got him". The idea of a drive-by shooting would never have appealed to Montresor. He wants to kill Fortunato, make sure Fortunato knows it is Montresor who did him in, and never get caught himself. Walling Fortunato up in the catacombs under his property is an ingenuis way to do it and apparently, Montresor never gets caught. At the end of the story, Montresor states that the bones guarding Fortunato's tomb have not been disturbed by any mortal in more than fifty years. In pace Requiescat.
