This book is a great book, full of exciting plot twists and surprises. Ever wanted to read a good mystery? Well, this is the book.
Main Idea
The main idea of this book is that teamwork can get you out of many messes. An example of when this plays true is when, in the beginning of the book, (SPOILERS) in chapter 3, Joe falls into rushing water, and Frank and Chet have to work together to save him. This shows teamwork because Joe is still alive by the end of the book, and if Frank and Chet hadn't worked together, then he would've surely drowned. (END SPOILERS)
Another example of this teamwork is when (SPOILERS), starting on page 119, Frank wakes up, and there's a fire raging through the cabin they are sleeping in. Frank wakes the other two boys up, and they all get blankets, cover themselves with them, and run out of the cabin. When the building finished burning down (there was no use of calling the Fire Department, as they wouldn't have gotten there in time) ashes are't hot, they go in, and work together to find clues. This also shows teamwork because if Frank didn't wake them up, they didn't help each other get out, or if they didn't collaborate to find clues, the former two would mean that most likely, they would die in the raging infernos, and the latter one would mean that likely, they would never figure out who tried to end their lives. (END SPOILERS)
Both of these examples show teamwork and collaboration, as you can see. Therefore, the main idea
of this book is that teamwork can get you out of the worst situations.
