In the city that never sleeps, Dr. Piper's search for the perfect wedding dress turns into the search for the perfect murderer. When famous diva Veronica Forks drops dead after eating a bag of Ken's Killer Kale Chips, suspicion falls on former-mafioso-turned-surfer-dude Ken. According to Piper's PI flashcards, Ken has the motive (she witnessed a tiff between him and Veronica), the means (the kale chips), and the opportunity (he was at the expo). But Piper's sure the surfer-dude can't be a killer and, as any good PI knows, the flashcards aren't always right. Plus Brownie, Piper's pet pot-bellied pig, is addicted to Ken's Killer Kale Chips, and if Ken's arrested, Brownie will never snack again! So Piper takes it upon herself to root out the murderer who's adding "killer seasoning" to kale chips before he strikes again.
