I was silly enough to pay the full Amontillado price without consulting you in the matter.You were not to be found, and I was fearful of losing a bargain. And I my doubts and must satisfy them.... My friend, no. It is not the engagement, but the severe cold with which I perceive you are afflicted. The vaults are insufferably damp. They are encrusted with nitre.
My dear Fortunato, you are luckily met. How remarkably well you are looking today. But I have received a pipe of what passes for Amontillado, and I have my doubts.
How? Amontillado, A pipe? Impossible! And in the middle of the carnival! Amontillado! Come, let us go. To your vaults
Come. We will go back; your health is precious. You are rich, respected, admired, beloved; you are happy, as once I was. You are a man to be missed. For me it is no matter. We will go back; you will be ill, and I cannot be responsible. Besides, there is Luchresi —. Drink.
Nitre. How long have you had that cough?
It is farther on, but observe the white web-work which gleams from these cavern walls.
It is nothing. -Enough, the cough's a mere nothing; it will not kill me. I shall not die of a cough.
The pipe! Nitre?
THE CASK OF AMONTILLADO
Pass your hand, over the wall; you cannot help feeling the nitre. Indeed, it is very damp. Once more let me implore you to return. No? Then I must positively leave you. But I must first render you all the little attentions in my power.
When Montresor meets Fortunato, he explains the situation to the reader.
Fortunato gets trapped.
No answer still. I thrust a torch through the remaining aperture and let it fall within. There came forth in return only a jingling of the bells. My heart grew sick; it was the dampness of the catacombs that made it so. I hastened to make an end of my labour. I forced the last stone into its position; I plastered it up. Against the new masonry I re-erected the old rampart of bones. For the half of a century no mortal has disturbed them. In pace requiescat!
Montresor chains fortunato to the wall of catacombs.
True, the Amontillado.
Montresor used and mortar to wall Fortunato into the niche while Fortunato is in pain. & leaves fortunato to die.
Montresor never gets caught but he tells the story of how he killed him.
