As they reach their final destination Fortunato discovers a very disturbing thing. There is no Amontillado, but chains. Fortunado is to astonished to resist as Montressor clamps the chains onto Fortunato. It is too late.
"Ha! ha! ha! — he! he! he! — a very good joke, indeed — an excellent jest. We will have many a rich laugh about it at the palazzo — he! he! he! — over our wine — he! he! he!"
As the last bricks are laid by Montressor, Fortunado pleads to him of not doing this deed. It is too late to stop. Fortunado has gotten his final revenge. Fortunato's life will be gone in the catacomb.
