Gr 1-3 In this installment in the series, Milo and Jazz, with the help of their pen pal, private eye Dash Marlowe, discover why everything seems to be going wrong at the 4th of July fair. Weird things happen left and right, like the Hottest Chili Pepper contest entries disappearing. Is it sabotage or just a series of unfortunate accidents? The story is simple, and children will enjoy solving the mystery. Black-and-white spot art appears frequently throughout, creating a text that will not intimidate children just starting to read chapter books. A good choice where the earlier titles are popular.
