Elvis Purrsley Has Left the Building

Welcome to Yesteryear, the small tourist town where every day is still 1950 or 1960-something. Poodle skirts are in, the sounds of Elvis Presley and The Supremes fill the air, everyone is kind, and bad things never happen... or at least that's what the brochure says.

I wasn't looking for trouble when I returned to Yesteryear for my great-aunt's funeral, but I certainly came to the right place.
My first surprise was that I'd inherited Aunt Della's beloved cat, Elvis Purrsley.
My second surprise was that she left Yesteryear to the cat... but only if her murder is solved within thirty days, which brings me to the third surprise: Aunt Della was murdered, or at least that's what she claimed in the video she left behind.
Most of the family thinks Della was crazy to believe the psychic who foretold her death, not to mention leaving the town she founded and most of her estate to a cat and threatening to sell off the town if her murderer wasn't caught before the month was out, but then someone tried to kill again...
If no one else is going to take the case seriously, it's up to me and Elvis Purrsley to find the murderer and save the town.
