It's party time!
Halloween has come around and Mel, Greg, and Jackie have been invited to a Halloween party. Oh yeah, and Rachel tags along too (yup, she's back)! Everybody is having a great time when suddenly, one of the guests is killed right then and there, in front of everyone! Detective Shorts and some other officers in blue show up and start interrogating the guests, trying to figure out what the heck happened at the party. Mel herself stays out of it and lets the police do their job... HA! Did you actually fall for that? Because she totally did not do that, lol. Detective Shorts has pretty much resigned himself to getting Mel's help whether he likes it or not, so Mel goes off to investigate the murder her own way, with the help of her friends, of course. Drunk ghosts, evil twins (maybe?), and lost money... oh my!
