I really enjoyed reading this book because it was really suspenseful finding out who the culprit was. The neighborhood was suffering great pain when someone decides to see all the valuable items of the characters, such as the baseball cards. The third grade class, teacher and police collaborated to find the culprit. The teacher gives them hints. The protagonist decodes them, but doesn't quite understand the correlation between the culprit and the hints. However,as the story goes on the hints get clearer and clearer.This book taught me many lessons as well. The lessons are to work together with each other effectively and efficiently, think logically and never be discouraged. These skills are essential in school and in society. However, at times, I seem to be lacking these skills. At times, I would not be a cooperative partner, a straight thinker or an optimistic person. This book taught me the essence of the skills. If I possess all three skills, I will be a better, more successful and happier student and individual.
