re-watching the first guy ritchie sherlock holmes because someone posted a meme edit of a scene, and I remember enough of the "here's how he did it" from near the end to start to see how you could in theory work it out live. I think there's actually enough information to do it in places, which is rare. even in sherlock holmes originally, the books are frequently the "this information we never gave you is the answer" about the mysteries, which I hate.
