Montresor leads Fortunato to where the recess in the wall is. Suspense if very high in this area as Montresor told Fortunato this is where the Amontillado is. This is the final level of suspense in the story before Fortunato is left doomed.
Montresor chains Fortunato to the recess and he is trapped there. Montresor states, "Throwing the links about his waist, it was but the work of a few seconds to secure it."(Poe,71). This is significant because it is when the suspense is released and the final act of the revenge is started.
Montresor continues to build his wall. Montresor tells us that, "succession of loud and shrill screams, bursting suddenly from the throat of the chained form."(Poe, 77). Fortunato has finally sober and realizes the situation he is in. This is significant because it shows the feelings of Fortunato and he regrets what he has done.
Montresor finishes his wall and makes sure Fortunato is dead by calling to him and throwing the torch inside the recess. This is significant because the deed has been done, yet still Montresor feels hardly any guilt for what he has done.
