The Case of the Lost Key
Detective Leo had a massive problem. His shiny brass key was missing, and the school library door was locked! He knew he had to find it before class started. Leo began his investigation in the quiet hallway. He checked inside his heavy leather backpack, but he only found a broken yellow pencil and an old map. Next, he sprinted to his classroom and searched under his wooden desk. Still no key. Leo decided to check the outdoor garden behind the gymnasium. Under a giant oak tree, he spotted a small iron box hidden in the green bushes. He walked over, brushed away the dirt, and slowly opened the lid. Inside the box, the key was shining brightly in the warm sunlight! Leo smiled; the great mystery was finally solved.
