Well, just the fact that the characters are all dressed up for a masquerade party, already adds to the eerie mood. But what really seals the coffin is when Montressor lures Fortunato into the catacombs, and then ties him up. You really get the whole creepo-vibe, when Montressor starts to seal up the "tomb". Hope this helps you a lot.

Ending the adjectives with -ed is not needed, so those answers are out. As for the numbers, the rule is usually that numbers one through nine are spelled out whereas number 10 and up are written in numbers. That said, you do not hyphenate the number with the word, so four-letter word would be correct.
