Calvin was in his room, reading comic books with Hobbes when his mom knocked on his door "Calvin?"
"Come in, mom" Calvin replied, still focusing on his book.
Mom entered the room "I have something to tell you. Tonight me and your father are going to New York City to see The Lion King with your aunt Melanie."
"Oh boy!" said Calvin as he bounced off the bed and ran into his closet. He burst back out wearing an "I Heart New York" shirt, a pair of sunglasses, some jeans, his dress shoes, and a necklace with a faux gold dollar sign on it while he was holding his iPod that was playing "Empire State of Mind" by Jay-Z.
"No, no!" snapped mom, who instantly snatched the iPod and turned it off "You're not going. Rosalyn is coming to look after you when we're gone."
Calvin's eyes grew wide. He ran back to his closet and shut himself inside "Don't open the door until you get back!"
Two hours later, Rosalyn came.
"Oh, good, you're here, Rosalyn." said Mom as she opened the door "Calvin's in his room. Help yourself to anything in the fridge. We'll be back by morning."
Rosalyn's eyes were bright green. Her nails were unusually long "Don't worry" she said "I'll take good care of Calvin. Enjoy your trip. Mom and Dad left out the door. Rosalyn instantly shut it closed and jumped onto the couch. She turned on the TV and flipped it to the movie channel "Welcome back to our horror movie marathon. Up next: It Came from the Basement!"
Calvin and Hobbes creped down the stairs and tried to watch the movie without getting caught. Suddenly, Rosalyn turned around and caught them "YOU!" she yelled "Get back in your bed!"
The force of the scream sent poor Calvin and Hobbes scrambling for Calvin's room. The ran inside and shut the door closed behind them "What the heck is up with Rosalyn?" asked Hobbes "She's never like this!"
"I know. You don't think…"
"Think what?"
"You don't think a demon possessed her?"
"Demons? You believe in that stuff?"
"No, but I read this book at the library about monsters and stuff, and it said that a demon can possess the soul of an evil spirit and have them carry out their evil whims!"
"OK. Now how do we find out if Rosalyn's really possessed?"
"We search for clues" said Calvin.
"Oh boy! Snooping!"
