Final answer:
Montresor hopes for peace for Fortunato's soul
Step-by-step explanation:
In the story "The Cask of Amontillado" by Edgar Allan Poe, Montresor says, "In pace requiescat" when he has finished sealing Fortunato inside the catacombs. The phrase, which means "May he rest in peace" in Latin, suggests that Montresor hopes for peace for Fortunato's soul.
