A Mysterious Cabin

The cabin was completely hidden among the trees, so you would never notice it from a distance. Mark was utterly shocked and suddenly had so many questions about the structure. Construction is not allowed on the property, so the cabin was clearly illegally built. But who built it? And why would he build it there? One thing comes to mind. The person either wanted to distance themselves from the world or escape the law. But which was it? Mark had no idea who could possibly use the mysterious cabin and for what.
