This is a very nice short encounter: it's a systemless one-shot designed for a modern cryptid-hunting game. The PCs might think they're on the trail of a werewolf, but are they? This really benefits from its local colour, being based in specifically American modern, if not urban, legend. It leaves the truth about the cryptid open, so there's some potential for moral dilemmas and tragedy here. For such a brief product, it does everything it should: hence the five stars.
