In "The Cask of Amontillado," to whom is Montresor telling this story?

There is some evidence
to suggest that
Montresor might be speaking to a priest. In the beginning, he addresses
someone
who, he says, "well know[s] the nature of [his] soul." A priest,
certainly, would be
one to whom Montresor might have made confession in the
past, and, in this way, such an auditor
would absolutely understand Montresor
and know him quite well.

Secondly,
Montresor does seem to
be confessing now. In the end, he says that the events of this story took

place "half of a century" ago. This means that he is now an old man. If he was in
his
mid-twenties when these events took place, he'd be in his mid-seventies
now. It is possible,
then, that he is making his final confession to a priest
before receiving his last rites. If he
has held onto this information for so
many years, it might have been weighing heavily on his
conscience, though he
only now confesses (when he's so near death) because he doesn't want to

suffer any consequences...
