This is a complete 919 piece Ravensburger puzzle called Escape the Circle London. Once completed, you can solve a series of mysteries, although the very final answer is meant to be used with the answers from the other two puzzles in the series. It comes with everything except the bag the disc came in. The answer key is still sealed as I used the one on the website mentioned in the instructions. The box shows some signs of wear. Note: This is from a pet friendly home. I will have other puzzles listed as well, mostly used. I enjoy working on them in my free time, but need to downsize the amount of them I have ended up with a bit now. Please see pictures for more details and feel free to ask questions or make offers!
