In his efforts to redress the "thousand injuries" that he feels Fortunato has committed against him, Montresor lays a careful plan to ensure that his retribution is performed with "impunity":
- He ensures that Fortunato will not be missed by planning his revenge at the time of the "carnival," which is the celebration of Mardi Gras, the day before Lent. People are in masques and costumes and celebrating with libation, so the absence of Fortunato is one that will not easily be observed.
- Montresor tempts Fortunato's excessive pride by telling him, "As you are engaged, I am on my way to Luchresi. If any one has a critical turn, it is he. He will tell me--" In jealousy, Fortunato replies, "Luchresi cannot tell Amontillado frm Sherry."
- Montresor manipulates Fortunato, urging him not to enter the catacombs because he has a cough and the niter is damaging to the health, knowing full well that the man's pride compels him to enter. Frequently, too, Montresor acts as though he is concerned fot the man's health: "...we will go back;you will be ill, and I cannot be responsible. Besides, there is Luchresi-----"
