When is the Mood Determined in The Cask of Amontillado?

I read this story last school year.The mood is more of an eerie mood.

The mood is one of suspense, because the character Montresor has determined to murder Fortunato. Montresor invites Fortunato to his home to taste an fine wine, an Amontillado. Montresor is exceedingly polite and friendly to Fortunato, although the reader knows Montresor intends to murder Fortunato. The suspense is as to how and when the murder will occur.

The mood of The Cask of Amontillado would be either suspense, or just sort of a mystery.
