For the record, my actual theory isn't aquawerewolves, I think it's that the Wolfs are the inner circle of some kind of sun worshipping Lovecrafty cult that needs to provide sweet foreign blood to appease the mini cthulhu in the lake every solstice. Not a solid theory, I'll admit...
Just for my own amusement, I'd like to know what each of you thought was going on. I don't think any of you will actually get it (because you straight-up didn't have enough to go on at that stage), but I was firing Red Herrings at you like a tennis ball launcher, so I'd be intrigued to know what you picked up on. I'm actually really, really sorry (in all senses of the word) that we didn't get far enough into this for the actual mystery to become at least a little bit exposed.
When we start anew, will it be a new mystery entirely or along the same sort of spooky paranoia manor lines?
That would be up to the new GM, natch. Some things totally work about the manor setting - the GM has an environment that they can totally control which completely justifies the isolating a group of characters. On the other hand, there are lots of things that have to be worked around that arbitrary starting point which limits - or indeed, inspires - what you can and can't do. For what it's worth, the golden age of murder mystery writing took place long before mobile phones, and they're the first things you need to justify not working if isolating the cast from the real world is a necessary part of the plot.
In the unlikely but not implausible event that I'll be running another one (at least, any time soon), obviously all of the stuff I had in store for Wolf is now unusable (by me), because here's a GDoc ruining it all for everybody.
It's entirely possible that I've watched too much Jonathan Creek lately, because I actually wrote that GDoc like an actual fucking denouement. If none of you has seen Jonathan Creek, it's a quirky British mystery show where a self-effacing, socially-awkward deviser of magic tricks for a famous magician reluctantly works out mysteries using principles of how magic tricks work. It's less interested in whodunnit and more in howdunnit. Definitely recommend.
