A demand from Death itself is quite the way to hook an adventure and yet again one that I appreciate for doing something outside the box. There's even a ticking clock! This is pretty complete and ready to run as is, maybe even without having read it before which is always awesome in my book.
This is the kind of scenario writing that does plenty with very little wordcount and could easily inspire a meaty session of roleplay given all the stuff that's going on in the location.
Very well done!
