Monster is seeking his revenge on Fortunato after he ventured upon insult and he will do anything to get it.
I vowed my revenge.
Fortunato really prided himself on his knowledge of wine and Montresor tells Fortunato about a pipe he has received.
Amontillado? A pipe? Impossible! And in the middle of a carnival.
But I've received a pipe.
Montresor convinces Fortunato to go to his vaults and find the Amontillado.
Let us go, nether less. The cold is merely nothing. Amontillado! You have been imposed upon
Montresor and Fortunato search the catacombs to find the Amontillado.
But let us proceed to the Amontillado.
Montresor chains Fortunato up and locks him behind the wall.
Pass your hands over the wall; you cannot help feeling the niter. Indeed, it is very damp. Once more let us implore you to return. No? Then I must positively leave you. But I must first render you all the little attention in my power
Montresor places the last brick and leaves Fortunato to die behind the wall
