Search for hidden compartments in tools

Well you start to get down on your hands and knees and start to look for things out of the ordinary. Then you realize you never really been to prison before you only seen them on pictures or things like that sometimes movies but they're not accurate. (I gave a heavy sigh to your option.) You start to look and after 5 minutes of searching the whole room he knows to handle the same could be unscrewed so you start to unscrew it. When it was fully unscrewed you found a key shoved into it but you don't want to stop there from your searching. You start looking for things that could be helpful like a flashlight or a gun. After 25 minutes of searching you found a flashlight under the pillow on her bed. You start to go to the bookcase and throw book after book on the floor after two and a half hours you found a book that would not move.
