Mickie McKinney: Boy Detective, The Case of the Absent Answers

Mickie McKinney is Maple Ridge Middle School's one and only private detective. (Not that anyone else wants the job). So when the new girl is accused of stealing the history test answers, Mickie is the only one who suspects there might be someone else behind the crime. With the help of an orange smudge, the school's mad scientist, and wisdom of his late father, Mickie is willing to follow the clues and unmask the true culprit...except the new girl doesn't want his help.
