Secrets at the Chocolate Mansion by Leslie Margolis

3.0

Maggie's friend Sonya's mother just opened a fabulous old-fashioned soda shop called Sonya's Sweets, but when Maggie and her friends show up for the grand opening, everything is going wrong. Someone switched the salt and the sugar in the pie, the big stain glass window is broken, and an ominous note is found among the shards of glass. When orders go missing and the power goes out, it appears that someone is sabotaging the business. Can Maggie figure out what is going on before it is too late?

This is the third book in the Maggie Brooklyn series. I have not read the first two, but it looks like a fun mystery series. recommended for grades 4-7.
