No good deed goes unpunished, as television star Marla Dane learns the hard way. The recently fired TV detective, trying to figure out her next move at her sister's Minnesota condo, reluctantly agrees to sub as Water Girl at a weekend pickleball match. Which makes her the first suspect of many when the team captain turns up dead.
Eloise Wallace, owner of a local PR company, will never receive the title Boss of the Year. She's dragged her staff, her old college roommate, and even her ex-husband and ex-employees onto her pickleball team. No wonder their success on the court is so sad. They all have reasons for wanting her dead, and Marla and former cop Rex Alcorn are enlisted to figure out who poisoned her.
As Marla's sister Kitty distracts them with a new obsession, pie baking, Marla and Rex find their suspects crusty and evasive. The victim excelled at making everyone around her miserable, so what did the killer have to gain by staying in her life — or ensuring her death? The answer may be more toxic than either of them bargained for.
