What A Nunderful World. Nun of Your Business Mysteries, #5

Hello! It's me again, Trixie Lavender and my best demon friend the stoic but adorable Coop. Things have been going pretty great for us these days. Inkerbelle's Tattoos is doing well financially. Our clientele is growing by the day, and we're about to purchase the guest house we've been living in from our dear friend Knuckles. Finally, we'll have the roots we've so desperately yearned for. Now, if only we could figure out how to get rid of the troublesome demon inside me...
We've also been focusing on Coop and her efforts to live her best life. As a newb to Earth, she's on a quest to experience as much as she possibly can and that includes her latest passion, makeup. While attending an event for Coop's favorite beauty guru and online superstar Glitzy Mitzy, we watch in horror as she dies right before our very eyes. Naturally, we suspect foul play, but with no clues, and the police not calling Mitzy's death a murder, we have little to go on.
But does that stop me? Nah. So you know what that means-it's time to break out our best spyware and solve this murder!
