Murder hits a little too close to home for bakery owner Lexy Baker when a grim discovery is made in her homicide detective husband, Jack's, basement. With Jack as the main suspect, Lexy has to turn up the heat and find the real killer while still trying to whip up the perfect meringue cookie recipe for the Brook Ridge Falls Desserts Contest. Normally, she would enlist the aid of her amateur detective grandmother, Nans. Except ... Nans has a secret and is uncustomarily disinterested in investigating. Not to be daunted, Lexy turns to her iPad-toting posse of grandma sleuths who help her sift through the clues in an investigation that keeps dishing up the most unlikely suspects. When a surprising twist causes Lexy to suspect those closest to her, it makes her wonder if some things from the past aren't better left alone.
