Sophie and Grace are best friends who have made a game of spying on their neighbors. But when they stake out the home of notoriously phony middle school guidance counselor Dr. Charlotte Agford, they stumble across a terrifying scene.
Or do they? What the girls thought was a bloody murder scene was merely the carnage from Agford’s preparations for her famous pickled beets. Still, her sugary sweet facade and trademark dead-eyed smile convince Sophie and Grace that something doesn't quite add up about Dr. Agford—and they're determined to get to the bottom of things.
But as the girls crack secret codes and mastermind dangerous missions, their friendship begins to buckle under the strain of the investigation. Even if they uncover the truth about Dr. Agford, will their friendship survive?
