When Maddie Springer—shoe designer turned amateur sleuth—tags along with her mother to the Antiques Extravaganza road show, the last thing she expects to have to do is pull her mom off of a celebrity appraiser after he calls her prized antique hatpin a phony. But things go from harried to homicide when the same appraiser is found dead—killed by Mom's hatpin! Now not even Maddie's husband, LAPD Detective Jack Ramirez, can save Mom as the force's two most bumbling detectives are assigned to the case.

As if Maddie doesn't have enough on her plate, her best friends, Dana and Marco, enlist her help to plan the most over-the-top Hollywood surprise party for Dana's fiancé (who has a little surprise of his own), Maddie's twin toddlers are always up to no good, and the only thing that can calm her mom down is aura cleansing from her favorite psychic. Whether they help or hurt, Maddie's friends assist her in wading through a slew of murder suspects—none of whom are telling the truth and all of whom have ample motive. Was it the frigid business partner? The clown-collecting fan-turned-stalker? The auction house owner with a grudge? Or was the appraiser's real business something much more sinister than his TV personality let on? Maddie and her eccentric gang of unlikely sleuths are under the gun to find out before the real killer strikes again and Mom takes the fall!
