The Cask of Amontillado sprang to mind for me, too. A lot of similarities and I think they were purposeful. I grew up in Vegas so I am very familiar with the area. SK did a great job of setting and place. The story is paced well - you never feel rushed or like it's being dragged out. Ghost story? Mayhap. I guess that's up to us.
I did pick up an unusual mistake. When the protagonist tunes into the radio, he tunes in to an impossibility. There is no WKXR in Vegas, nor could there ever be. Radio and TV station call letters west of the Mississippi River start with a K, not a W. A rare flub from Uncle Stevie.
